What is under Santorini that makes it so dangerous? (it's not just earthquakes)

- New earthquake video here:
• Why are there fault li...
Santorini has been experiencing many earthquakes, resulting in evacuations...but the earthquakes aren't the only possible issue in Santorini. Santorini has a destructive volcanic history and has lots in common with "ring of fire" volcanoes elsewhere on Earth. This video shows what's under Santorini to produce its volcanic behavior. Parts of the Mediterranean are actually just as dynamic as the Pacific Ring of Fire, even though we don't always think of them that way!
As this event is increasingly clearly a seismic one, the most relevant part of this video is the stretched continental crust! The stretching is ongoing, and the stress contributes to earthquakes in the region. Use this video as a basic overview of why this region of Earth is very active and has the potential to experience dynamic events.
Finally one of the Geo Channels got it right, the earthquakes are all directly in the Zone, where the molten Rock,Gases comes up, to feed the Santorini volcano and Kolumbo Volcano.
Does not mean that something needs to happen but the quakes mean, that there is a lot of movement under these Volcanos, they need to find out, how much more Material is coming up, in the chambers and how fast.
I was on Santorini a little over two years ago and when you are on the beach, it’s not sand you walk out into the water and you’re standing on a giant undulating rock that’s what it feels like there’s no sand. It’s just a rock and it makes you very aware that you are on the edgeof a volcano.
To find that out they should ask AI how to do it
GeoModels, thank you! I see soooo many playing this off as just plates, I don’t believe it. There’s way more to this than what they’re saying!….
@@lissyflur1907 So you don't know GeologyHub.
Hi from Athens. Just to help understand the situation, the current seismic activity isn't located in the volcano of the island, but has shifted further North East, between Santorini and Amorgos, where is located another underwater volcano.
So, we’re potentially getting a double eruption?
@@FarfettilLejl No, there hasnt been seismic activity at the caldera of Santorini. All of them are happening a bit to the North East of Santorini. If you look at the map, it's between Santorini and the two Northern islands that these activities are taking place.
@@zedsian right but a potential eruption of the other volcano (Kolumbo) could trigger an eruption of Thēra/Santorini, no?
Kolumbo wright?
Sorry, but that doesn't fit the narrative of western media agencies, and the hundreds of hours of B-roll footage of Oia and the Caldera that they can't wait to use!
jk, appreciate your input!
Hi from Greece dude, nice explanation here but. The Greek seismologists are not afraid for the Santorini Caldera but the underwater volcano called COLOMBUS witch is located about 7 miles north east of the island of Santorini witch is right under the point of the map where all the earthquakes located. Columbus is far more bigger volcano, its caldera measured to be 1 1/2 km wide in 500 meters depth. in the area are also located 2-5 faults from 20 to 40 km long (the main one near the island called Amorgos witch in 1956 give us an earthquake of 7.5 ....
would you expected a major tsunami as the result of an eruption affecting both Greek and Turkish territories, including their mainlands?
@@MrWotcher this is exc what happened in the earthquake of 1956. Not mainland but for sure the shores of both country's. 1956 caused a tsunami of 2-3 meter high effecting all the surrounding islands.
@@MrWotcher Yes, but we don't expect any eruption, and not a major tsunami, even if a major Earthquake were to happen.
What do the Greek seismologists say about its effects? Do they think Columbo will affect Santorini, Amorgos, or some of the other islands? I'm headed there in September this year, so this is a real concern.
I wish there was a follow-up video given this information
Excellent graphical presentation! I married a Greek girl 22 years ago... the first island I ferried to was Santorini in 2003. Sailing into the caldera is a sight to be seen at least once in your life. Bucket list worthy. We returned many times over the years, Milos, Serifos, Skiathos and most often to our beloved Naxos since 2005. The swarm is pretty impressive with so many M3 and M4 tremors, sometimes six or more per hour. Amorgos had a M7.7 in 1956 which generated a tsunami. The swarm is not far from there, geographically speaking. Should be interesting in the coming days. Hoping the best for Santorini.
In between 1947 and 1957 there were four M7 earthquakes in Greece, with no large scale casualties.
The 1956 earthquake in Amorgos island generated a tsunami over 25 meters.
OK, now I am jealous!
Oh David,i feel sorry for you ! Greek womans are tough like hell 😂
@@Mfoukos haha! Good one. :)
@@DaveTinNY 😅
I wish I’d had a teacher like you at school. Thank you for your really interesting lesson.
A great way for us to understand what is going on! Here they don't explain. Thank you, greetings from Greece!
well it seems like the activity is related to stretching the crust as I draw instead of volcanic activity. we will hope this is true! it is a dynamic area.
I had read about it this morning and was wondering if this was one of those "extreme disasters" in the making. If I lived there and had a couple hundred earthquakes in 48 hours, I would be packed and gone and as far inland as I could get away from it. I hope it stays safe for everyone to get off of the island. Thanks for explaining it!
💯
most of the people left the island
Analysts here say its not in the couple of hundreds range. Its in the thousands range. It was 6k up until yesterday. Duuuuuude
If the volcano on Santorini Island in Greece erupts, it could affect Greece, Turkey, and other countries in the region.
Affected countries
Greece: The island of Santorini is located in Greece. The Greek government declared a state of high alert after a series of earthquakes in February 2025.
Turkey: A Turkish professor warned that the coastal cities of Turkey could be severely affected by an eruption. Ash from the eruption could reach Turkey by wind and ocean currents.
Other countries in the region: The eruption could also affect other countries in the Aegean region.
Potential consequences
Droughts: A volcanic eruption could lead to a drastic increase in droughts.
Ash clouds: Ash clouds from the eruption could rise as high as seven kilometers, which could disrupt flights and cause engine failure.
Tsunamis: The eruption could generate tsunamis.
Landslides: The eruption could cause landslides, especially in coastal areas.
@@eladentopistevo Was like the first day I read the report and it said a couple of hundred. I knew it was a lot more now. Not a dude 😁
Thank you for this non-dramatic and simple explanation of the facts. It is appreciated.
Also, your paint visuals are very helpful!
You are a great teacher! Subscribed back when you were explaining the North Carolina flooding disaster and I’ve learned quite a bit just listening to you 👍
Yes me too! Thanks so much, I lived in WNC and those videos you made were fantastic
Greek here from Athens: everyone's afraid because in 1956 in July, a few days before a 7.8 magnitude earthquake happened, multiple smaller quakes happened. And it caused a 30m high tsunami.
That gives context. Thank you.
😮oh no. That sounds terrible. Thank u for that info.
Very informative, thanx for the update
Eos is very close,Santorini is quiet Spooky.Didnt spend a, great deal of time there.Crete was a great place to get around to explore.
😳😳😳
Never thought I would actually understand. It really just takes a great teacher. Thank you!
Very informative!
Thank you for being you and being here teaching us all something!
Classic TH-cam - a guy explaining, very well, complicated interactions on MS Paint. Love it.
Thanks, interesting and clear description. We have a similar situation here in New Zealand. This looks a lot like our Taupo volcanic system, a caldera volcanic system. Taupo has been quiet for quite a while, but nearby White Island continues to rumble. I let my son know, he is a volcanologist here. He tells me he is on standby, to go to Spain to help, or for a holiday.
The problem is more complicated if you consider that there is an underwater volcano just above Santorini. This volcano is called Columbo, which according to measurements in recent years has shown an increase in the gases it emits. The latest earthquakes are shifting towards the island of Amorgos and near Columbo. This fault has caused a 7.7 earthquake in 1956, which caused a tsunami that reached 20 meters on the island of Amorgos and simultaneous small-scale activation of the Santorini volcano. The history of this volcano is even more tragic during the period of antiquity with the destruction of the Minoan civilization in Crete
But it is the volcano that's causing this. If it was just the usual tectonic activity it would have either ended by now or reached it's climax.
In Japan, before the megaquake, there was a swarm of small earthquakes, not 4s and 5s. Then two days before the main event there were just two foreshocks of 7 and 6 magnitude.
This is not the case here. Here we're seeing an increasing, non stop activity, all around and inside two ACTIVE volcanoes, which clearly indicates volcanic activity. When we're saying volcanic activity of course it includes tectonic activity. They're interlinked.
Why people don't understand this i do not know. It's simple stuff. It's BASICS.
As you know as expert in the matter, earthquakes and volcano are not related. The recent erupción of La Palma is a clear demo of your assert
I do not question your status, just as I do not question other scientists such as the professor at the University of Patras, Mr. Zelelides, as well as other geologists. What I am saying is that recently there has been an increase in temperature and gas emissions in the crater of the Santorini volcano as well as the underwater Columbus. These may be related. You are a scientist but not infallible. I hope it is just another episode of the earthquake series that will simply weaken. Something similar has happened in the last year in the area of Thebes and Mount Athos in Greece with dozens of small earthquakes that did not cause anything more, even though the areas have had major earthquakes in the past. However, there are no volcanoes there. In this case, there is a continuous increase in the dynamics of the earthquakes that occur. It does not change much whether it is a volcanic eruption or a major earthquake. The safety of the world matters.
And what difference does it make WHICH volcano blows? The results is still the same, if people don't evacuate they will die.
@@xXturbo86Xx it’s the tectonic activity in a subduction zone that is causing the volcanic activity to occur, I’d recommend rewatching the video as around 3 minutes in there’s a more detailed explanation with visual references that help make it easier to understand.
Great description, as always. Thank you!
Worth mentioning that the last ‘big one’ at this location, about 3,600 years ago, destroyed the Minoan civilisation on Crete and had major climatic impacts worldwide. Not something to look forward too, though inevitable at some point in time…..
2400...😮
The "Minoan civilization" is Arthur Evans's PROPAGANDA. HE BUILD FAKE PALACE IN CRETE AND HE PROMOTED THAT SIMITES WERE LEAVING IN GREECE BEFORE GREEKS. His friend Marinatos BUILD FAKE PREHISTORIC BUILDINGS IN SANTORINI TO PROMOTE EVANS'S FAKE PROPAGANDA AND MARINATOS PROPAGADE THAT THE FAKE JEWISH -BRITISH CIVILIZATION DESTROYED BY THE VOLCANIC ERUPTION!!!!
A little further reading indicates that although the Minoan settlement on Thera ( Santorini) was destroyed, the centre of Minoan civilisation on Crete survived and rebuilt, and by some measures reached its peak after the eruption (and tsunamis).
Precise dating of the event is problematic, with estimates by various techniques varying from the mid 17th to the late 16th century BCE. 3600 years is near enough, by TH-cam standards!
‘Inevitable’ is also a touch absolute for a ‘big one’ centred on Santorini. A smaller eruption like those recorded at intervals from 25 to 150 years over the last several centuries is (arguably) inevitable, as is a big one somewhere on the Aegean sub-plate, at some point in time!
Such are the uncertainties inherent in trying to second guess Mother Nature’s shabby tricks……
@@Falcon-m9w I’ll see your 2400 and raise you 1200 !..?
Yes and no. The Minoans weren't fully destroyed but they were absolutely devastated by it. Most of their big centres were northwest of the island. Others were spared but their civ surely took a huge hit
This guy is a gem. Totally underrated.
(Didn't even realize it. Happy 4:20am. Good thing to be watching meanwhile. For science!)
Thank you for sharing your knowledge! I hadn't heard about the dangerous activity on Santorini.
You are an amazing teacher
I learn so much when I watch your videos. Thank you.
Awesome video! Thanks for explaining what is going on! My wife and I traveled there a couple of summers ago and visited the ancient village of Akrotiri on the island. It seems like I remember reading a theory that the caldera collapsing when it did corresponds to the plagues in Egypt in the Bible. Neat stuff!
I really love your podcasts. Thank you for explaining things so clearly.
Phillip, this Santorini dwg today terrific! You are so clear with your drawings and explanations. Thanks.
I'm reminded of the earthquake damage preserved in that delightful Minoan-ish* town buried by the 1600BC eruption on Santorini, signs that its townsfolk endured something like this before the end.
There's a wrecking ball in the ruins of a half-demolished house, a stone staircase with every step cracked in two by compression from the walls on either side, overturned pottery storage vessels they used like barrels, cracked and fallen walls and ancient repairs and new plaster. They seem to have suffered tremors for some months- but in the end, they evacuated before the final Krakatoa bang. There'e only one gold item in the whole city hidden under a floor tile, almost no jewelry or valuables other than bronze bathtubs and other large, heavy items. And, although the ashfall that buried the town before the pyroclastic surges preserved imprints of wooden beams and window frames well enough to capture the grain, there's no casts of human bodies. So I used to think this Bronze Age Pompeii had a relatively happy ending.
Sadly, the massive tsunami damage archaeologists have now discovered at the ancient port towns of Crete suggest they may have escaped out of the frying pan into, well, the soup. They were islanders and merchants, and quite likely would have been taken in by trading contacts in other harbors.
The Minoans' efficiently-run agricultural system coordinated by palaces survived for a few centuries, so this eruption didn't finish them off. But losing their harbors, ships, sailors, and probably a lot of supplies must've been a blow. They limped on for a few centuries before Mycenaean Greeks from the mainland (the same blokes that attacked Troy) took over.
*(Santorini was a trading hub; there's Egyptian wall paintings in one house and luxury items from other Bronze Age civilizations hinting that it was inhabited by a Minoan majority but a lot of citizens from all over the ancient world, like any big international city today. As you can tell, I fell in love with it as a classics major - no, it's not Atlantis, that was made up by Plato, but I can well believe folk stories of harbor cities and islands swallowed by the sea were based on old legends of the eruption, just like tales of the Trojan war turned out to be based on a real place that had certainly been attacked by Mycenaeans on more than one occasion.)
Fascinating 👍👍
Alot of work to write something barely anyone will read.
@@tylermcnally8232 many more than would hear a retelling verbally, and can be reread through antiquity...or at least until the Pork Reich locks down the internet
Here is what I posted earlier:
The Minoans, also called the Atlantians, was a highly developed culture who settled on the island of Crete. One day, in the open ocean north of Crete, the volcanic island Santorini [modern Thira] exploded and sank into the ocean. Consequently a giant tsunami devastated the island of Crete, from which the Minoans fled to the Greek mainland. There they encountered the wild, uncultured and primitive Hellenist descendents (Greeks) who were instructed by the Minoans in all arts and trades as well as in written and spoken language. Thus the Greeks got to know culture. Around two thousand years ago the Greeks glorified their half-gods whose highest god was Zeus, who allegedly is supposed to have lived with his sub-gods on Mount Olympus. Then came the Jewish prophet (Jesus) Galilean disciples, who preached Christianity. The Greeks promptly fell away from their belief in their half-gods and turned towards the new teaching. In later times the Greek Orthodox faith was constructed from that and essentially represents the true origin of the entire current Christianity in Europe: a religious false teaching, which indeed finds no equal in the civilised world.
@@tylermcnally8232Well, I read the entire post and it was a fascinating read.
Thank you for explaining this so clearly and in a way that makes it very easy to understand for those who are not geologists. This was interesting and now I understand what is occurring geologically in that area.
The whole Aegean Sea area sort of looks like a caldera.
Indeed frightening to think like that yet probably makes no sense to a geologist
The Aegean sea is so beautiful sad what’s happening
Hello 👋🏻 good to see you! I had no idea this was going on, but I don’t watch TV so there’s that. I hope everyone gets off that island safely
great information on the geology around Santorini. Your cartoon drawings are so good. Thank you
Many of the quakes are near Kolumbo and underwater volcano just northeast of Santorini.
This area has been seismically active for all of recorded history, and in fact a Greek god, Poseidon, was associated with earthquakes, and was called the "Earth Shaker."
We visited the beautiful volcanic island of Santroni during our family vacation in the summer. Even though it was a stunning place, we learned that in winter, strong winds cause even the locals to leave the island. Now, earthquakes are occurring there. It's always best to research an island’s seasonal conditions before booking a trip.
Yeah! but Mother Nature is so unpredictable!!
this was very helpful. i'm a 'visual thinker' and so this helped me 'see' what is going on (I'm only 200 miles north of Santorini). Geology is a hobby, my field is biology and sociology. this video was much appreciated. thank you. I'm concerned about the potential eruption and possible tsunami which will affect coastal regions. fortunately, although I can see Greece from my front door, we are 1000' above sea level. It's a great place to live. thanks again.
As a Tour Guide in the Island of Santorini thats the only thing that im thinking every summer all the time!! what IF this guy want to spit anything out !!!
Maybe some people cannot realize it but staying there for a long time starts to mess with your mind and slowly you got insecurities (if you take safety serious ofc).
Very nice video of you and very informative, appreciate it!
I’m supposed to be doing a cruise round the Greek Islands in July not sure I want to go now
@@rosemarymay3914 I hope that till the peak of the summer (jun/jul/aug) it will be safe for all of us !
Thank you so much for your Explanation
Prayers sent to Santorini✨❤️🙏✨
Great video!
I must say, you possess exquisite MS Paint skills my good man. Bravo!
Hi Philip, good to meet you. Thank you so much for sharing this. I am very happy to learn about our earth and how it works. Its like us, a living body and you have the ability to describe in simple terms how the earth works. Cheers brother, you are a diamond.
Inspector Clouseau of the Tectonics Department, totally brilliant and thank you!
You're so good at drawing the block diagrams.
I have been around the world multiple times and I have vacationed on Santorini twice. On the caldera side it is steep, dramatic as heck, with houses and villages clinging to the edge and in places, sagging towards the sea. On the beach side, it is a beautiful shore. I have taken excursions to the new volcano in the new mini-caldera. Walking on that terrain, with gasses and smoke oozing out was a remarkable experience. Add to that the ancient Greek archeological site of Akrotiri and the village of Oia at the tip if the western landmass and you have a very unique environment. I heartily recommend everyone consider a visit to this remarkable island! It figgers you would latch onto this remarkable location, Dr. Phil! 🤗
[W]ith houses and villages clinging to the edge and in places". I think these are the areas that are being evacuated because of the amount and increasing strength of earthquakes. They don't want people falling with their homes down the cliff. That's what I heard yesterday.
Yeah that would be great. Not looking too promising, though.

no wey thanks 😂😂😂😂
Visited Santorini last October. Also Crete and Mykonos, but luckily we felt no tremors. Hope everyone stays safe.
Great, I already paid for a vacation to Santorini in May. Hope it’s still there In a few months.
We shall see... A family member of mine wanted to visit eventually too. Gorgeous place.
it will still be there, but it will be different.
Much of what's there survived one of the largest eruptions since agriculture was invented, it will still be there. Now what's left standing or unburied is another story.
😄
Get the best sunscreen lotion you can find .. and plenty of it. The sun is scorching on that island
Thank you for the basics to understand more about the situation in Santorini. There seems to be quite of bit of noise on youtube regarding the earthquake swarm. Your visuals are revealing and they frame the geological process and many variables. The future is uncertain and worrisome. I am very skeptical of anyone who predicts what will happen next. I hope that you follow the developments and provide your comments as we move forward. thank you.
You did a great job explaining what is going on around the Aegean Sea . I would love to see you do a series on the different areas of the Mediterranean Sea . Started mentioning around Italy but other things going on around France , Spain
A few updates and trivia
1. The deep sea trenches in the south of Greece (collectively the Hellenic Trench) are way deeper than 3km. The Calypso Trench (outside Pylos) is some 5,200 meters deep and there are a couple of other basins at >4,000 meters. They 're the deepest places in the Mediterranean and they 're mostly unexplored.
2. The earthquakes in Santorini may not be directly related to the volcanoes, since they 're currently following a known local tectonic rift. Yet, as of yesterday, at least one magma chamber seems to be filling and there's considerable uplift both in Kolumbo (the volcano immediately to the north of Santorini) and Santorini. The situation right now is a bit perplexing.
3. The earthquakes' announcements are a bit misleading. The peak tremors are in the region of 5 R but in reality the ground is shaking all the time. It's not like there's an earthquake, then it stops and after a while another one begins. It's non stop shaking, often peaking at 4.5 - 5R.
Last, if you 've never been there, do yourself a favor and visit the place (needles to say you need to avoid peak tourist season). This small cluster of islands (Kyklades) has some of the most beautiful beaches on the planet.
3:49 deepest point of Mediterranean is over 5.5km or over 17k feet with an average of 1.5km almost 5kfeet. Just below Crete there is a underwater cliff basically that goes straight down for 2km. It's awesome to see. I literally sat on that edge when diving. Just looking into a blue abyss. Amazing.
The caldera reminds me of Crater Lake in Oregon, another gorgeous place to visit. Imagine a cascade volcano the size of Mt. Ranier blowing itself to bits, leaving only the giant caldera behind. A must see. A scary recent study shows that many volcanos, including Mt. Mazma at Crater Lake, still have active magma chambers beneath them. In theory it can become active and begin rebuilding itself at any time.
Been there it’s beautiful
So relaxing to watch your pretty drawing. I am learning environmental sciences, and earth systems is the amazing part.
Thank you so much for this really informative video of the ongoing situation in the Mediterranean ... a major event will happen ... only time shall know when...
Very informative. I learned a lot, thank you.
Also you taught me about how to use my laptop. Wasn't expecting that. Thank you again.
Santorini is a magical place. Of all the places I’ve been around the world, Santorini is my favorite.
48 seconds ago, that’s a first. Always look forward to your videos!
I am impressed. had to put a couple text clarifications on this one…did it right after realizing I have to purchase a new vehicle, and quickly. hope the big ideas still come through
Thank you. I am 70, but still interested in learning. This area is part of Paul's Journeies in the book of Acts. I remember the 1981 Mt St Helens.
I'm disheartened. I love Santorini, it is a beautiful island that everyone should see-especially before the shifting tectonic plates change the landscape! 7:13 The explanation of how the plates are pulling the land apart is mind-blowing and heartbreaking. 10:00 surprisingly good drawing, wasn't expecting this to turn into a Bob Ross video. Add some happy trees.
Thank you for taking the time to do this for us
Such clear explanation, great drawing, thanks
Loving this! Santorini figured into science-based Archaeology degree, tree-rings, ice cores, Minoan collapse etc. You're a great teacher.
As far as I now, the Santorini caldera isn't because of a direct collapse, but because during an eruption sea water penetrated into the magna chamber and caused a massive explosion expulsing much of the volcano top, and creating a massive tsunami that wiped out the Minoan culture on Crete in around 1600 BC.
Great stuff brother!
Very instructive and easy to follow thank you so much.
Thanks for posting this up. I think my parents are looking to visit somewhere in the Greek islands sometime this year and it could be Santorini.
Very educational. Thank you for your work!
Nice to hear geology, history of the land.
This illustration is how I learn - thank you and nice job!! 🎨
Thanks for a great explanation of what is going on under the ocean and what could potentially happen
Very nice presentation !
Thanx
What an excellent lesson. I was entirely engrossed
Love your updates
Thanks for the wonderful, educational video.
Thanks for the clear explanation. 🙂👍
Thank you for explaing what is going on without all the hype, and dramatic music that so many junk sites use 😅
WE SHOULD HAVE YOU ON GREEK TV
Thank You,I was hoping someone would explane it and you did GREAT!
Wow, really interesting and clear. Thanks
Thank you for this. This helps me understand what is happening You have such a simple way of explaining which I loved. I’m so glad I have already been to Santorini but def want to go back to. I really hope this work of Art place gets to stay. It would be such a shame if anything serious was to happen. 🇦🇺
nice drawing. I have stood on the edge of that volcano at Fira. That volcano is so impressive. If you know what you are looking at.
It's awesome!
I've walked that ash cone in the middle of Santorini. It was hot to the touch and stank of sulfur from all the fumes. Our guide said we would be able to evacuate quickly if the cone started shaking. I allowed that I would be highly motivated in that circumstance.
I am sorry for the fear and suffering occurring on Santorini. I visited there years ago and I remember thinking it was the most breathtaking place I’d ever seen in my varied travels.
🌹❤️✝️
just a reminder , when the santorini volcano erupts thousands of years back, it was sooo big, they even found dust from the smoke i suppose to antartica.
Hello from Athens-Greece. If I had to bet, I would bet on the earthquakes being volcanic not tectonic, due to the very high frequency of them. I am not a geologist, so I won't bet, but I have to tell you that here, in Athens, we have been feeling all the earthquakes over 4.5 RS from this area the last 4 days. Their frequency is quite unprecedented, even for us who are used to seismic activity.
Greece itself was a huge volcano and exploded since millions of years and then melted. This killed the dinosaurs around the world. Now Greece is in pieces.
Went to Crete years ago and the whole Minoan civilization was completely destroyed by the eruption of the vulcano of Santorini (1450 bc).
Thank you for such good informative explanation.
The explanation of this santorini caldera volcano is really good knowing nothing about geology or seismic activity. But I'm more impressed with Paint being used for illustrating it..😄
Calypso Deep goes down to 5200 metres or 17100 feet actually and it's the deepest part of the Mediterranean Sea
Humans: hey that island looks great to settle on!
Island: 🏝️ 🌋💥🏝️
We're not talking about Santorini but about Kolumbo. It's an active underwater volcano right next to Santorini. Anyway,unfortunately the "experts" the television always pushes are once again failing us. At least the Greek experts that is.
How can you call yourself an "expert" when you say that this activity has NOTHING to do with the volcano, when the earthquakes are happening pretty much all over the volcano AND inside it.
Volcanoes do cause earthquakes. Their activity creates enormous pressure and movement. I thought this was common knowledge among geologists and seismologists.
There are even reports from locals saying and showing that the sea level has dropped. Fishermen said that their fishing grounds have become shallower. Since the sea level doesn't drop localy and has been no change in sea level overall, it's safe to assume that the entire seabed has risen. But "experts" are once again oblivious. They accept nothing but their own opinion.
I recall holidaying in Greece and island hopping from Athens back in the 80's.A week on Santorini was very memorable and Akrotiki with its Minoan remains was so interesting.The caldera with its smoking ash island centre was a unique place to tread on.Best memories though were zipping around the island on moped scooters and listening to David Bowies "Is there life on Mars.?".It was high summer and 40.c everyday.Memories.!.
Thank you. Informative.
A major explosion on Santorini could have negative consequences for coastal cities nearby due to tsunamis.
wow, thats a very minimal way to say catastrophic.
It might rise up as new volcano Tunga under water or a slow island build next door
global effects just just local effects would cool the earth down by 4-5oC maybe more for years
Excellent work, thank you
Great video Marsh!
The Calypso deep , is more than 5 km deep , 63 km SW off the coast of Peloponnese . Also the deepest point in the Mediterranean Sea
Great job. And yes mantel minerals tend to be green!
Nice job!
Even the volcano could not handle the atrociously high airbnb prices on/off season and started shaking. It's alright, they just need to cut down to 25% of current rates and the volcano will stop growling.
/s
Do you have information on the volcanic activity on the island of Nysiros in the Dodecanese chain, closer to Turkey and near Rhodes and Kos.
Thanks for this. It’s a great lecture of the basic geological tectonic forces. I have learned to look at the google earth images with new found understanding. It was a very interesting and illuminating lecture. I’m glad to have visited Santorini and hiked the length. It may look different soon.
do you know if there is any good evidence for one of these volcanoes contributing to the bronze age collapse?
The Minoans on Crete and Thera disappeared and also the rise of the Mycanean culture
@@LindaMerchant-v2z This is Arthur Evans's PROPAGANDA. Arthur Evans build FAKE prehistoric palace in Crete and his friend Marinatos build FAKE prehistoric buildings in Santorini and he PROPAGADE THAT the volcanic eruption destroyed THE FAKE PREHISTORIC BRITISH PALACES AND THEIR FAKE PREGREEK CIVILIZATION!!!!!
There is a theory that the 1600 BC Santorini eruption (which caused the current caldera) might have contributed to the collapse of Minoan civilisation, but it's not very conclusive because Minoan culture continued on Crete for 200 years after the explosion. On Santorini there's an excavation of a Minoan port city, whose inhabitants fled before the explosion because there were no corpses found. What happened to them is unknown. There's (non-scientific) legend that Santorini was the origin of the Atlantis saga, but there's no evidence for that. There's no evidence that Atlantis is anything but a myth anyway. In any case one of the oldest hotels in Santorini is called "Atlantis" due to this legend.
I love the tectonics videos. For some reason the idea of an entire block of crust sinking like a stone is just fascinating. The mechanics of it seem impossible
The giant Campi Flegrei also has lot of reasons to worry about
thats an incredibly good drawing
awesome video!! first time I came accross your account and will follow
