Thanks as always, Geology Hub! While quite unrelated, the Tobaru volcano's recent earthquake swarm has made me think if the Indonesian volcanoes in that region are understudied, especially with the highly eroded cinder cones near the Tobaru volcano. I remember that one of the the 1808 mystery eruptions was suggested to be in Indonesia.
That is a major problem in a lot of the less rich parts of the world, they can't afford to study dormant volcanoes that are deemed a relatively low priority threat that extensively since more of the budget must be spent monitoring and studying the frequently erupting and more dangerous ones.
Hai GeologyHub, I'm from Indonesia. Can you tell me the source of the information that a Swarm earthquake occurred on Mount Tobaru? I have searched various searches about Mount Tobaru but nothing discusses about earthquake swarm
@@brokenwrench404My dude it is a single island it is surrounded by nothing but water. The idea is it could very easily cause as caldera forming eruption especially given its rate of growth. Geology has mentioned before he thinks this island is the most likely candidate for a VEI7 eruption albeit within a few hundred years.
@@RKOuttathebox : That is something the powers that be do not want people to know about. On account that is causing the ocean temperature to rise. There are thousands. The melting ice sheets COOL the waters. This however in turn effects great COLD globally. Like a desert. Hot in the day, freezing at night.
Iwo Jima is probably one of the potentially most terrifying volcanoes in the world, should it have another caldera collapse it could send major tsunamis accross the Pacific coast.
Is it possible that the main deeper magmatic zone that feeds Ibu and also Dukono volcanoes has become overfilled or overly buoyant. So the excess deep magma finds maybe the very old pathway that used to feed the new volcano that hhas been dormant for thousands of years ?
It's possible, and it's not that a surprise since West and North Halmahera Regency are filled with a lot of youthful-looking eruptive centers other than the three active volcanoes (Gamkonora, Ibu, and Dukono)
Also, since that area is mostly understudied, the latest eruption from these less-known volcanoes might be much younger than we expected, like just several hundred years to a few thousand years.
I've been watching your videos for quite a while now and it seems like there's always between 46 and 50 or so volcanoes erupting how does this flash out over the last couple hundred years is this a fairly typical number? It almost seems to me like somebody said a knob to that range and keeps it there. Is there cycles in the number of volcanoes that are actively erupting? I guess I have a lot of questions. Thanks for what you do
Q: You often say "a magma chamber is filling". Obviously, it is filling with magma, but what was there before? Presumably not water, or it would turn to steam and cause a phreatic eruption. Gasses? Air? Or volcanic gasses like CO2 and SO2? If so, does a "magma chamber filling" cause an increase of venting of such gasses? When uplift occurs, does this typically indicate that a full magma chamber is getting bigger?
Good question. Magma chambers are not typically voids that gradually fill as magma accumulates and fills empty space. Rather, they are already "full" and add more magma, which pushes out the walls and causes uplift due to the increase in pressure. Just like inflating a balloon.
My dad got to go to Iwo Jima while we were stationed in Japan. He had to make an emergency landing there and got to explore the island while his jet was being repaired
(Wikipedia) 15 November 1779: Following British captain James Cook's death on Hawaii, ships previously under his command landed on Iwo Jima during the return voyage from his 3rd expedition.[10] Under James King and John Gore, the expedition's surveying crew mapped the island, recording a beach at sea level which was 40 m (131 ft) above sea level by 2015 due to volcanic uplifting.[1] Such uplifting occurs on the island at a varying rate of between 100 and 800 mm (3.9 and 31.5 in) per year, with an average rate of 200 mm (8 in) per ye
The water body shown in the final seconds of the video looked remarkably similar in colour to the short lived lake that formed at the bottom of Halemaumau crater prior to filling up again…
Just a curious question, should the people in Tacoma and Seattle, Washington be afraid now? There's a few massive forest fires located around Mt. Ranier and Baker. Would they be severe enough to create lahar's over there?
Wildfires can't cause lahars -- they aren't occurring where there is a lot of snow and ice (which is mostly above treeline), and wouldn't cause mass and sudden melting anyway. Debris flows can be caused by sudden melting, and there are usually smallish ones every summer just due to high temperatures melting the snow and ice. The big lahars are almost all associated with eruptions. There's only one -- the Electron mudflow -- at Rainier that does not appear to have been coincident with an eruption.
I can imagine that the Mayon volcanic eruption was caused by rainwater weakening the structure of the cone, and allowing the heat from within to come into contact with the rainwater and cause it to flash-vaporize into steam.
A "Decade volcano" is just a designation that was given in the 1990s by a scientific organization -- they designated 16 volcanoes around the world for a decade of intensive study. The program ended in about 2000. Iwo Jima was not one of the 16 designated "Decade volcanoes." Has nothing to do with volcanic activity or potential.
no, pressure causes heat and as Earth continues to grow (40,000 tonnes annually) so the pressure slowly increases! also the crust is a great insulator keeping most of the heat inside
I love all the scientific and sometimes snide comments . The truth is we think we know until something happens that makes us realize we actually know nothing. I'm just hoping that when this realization occurs we can recover.
@@ajourney50 We actually know quite a lot, and more all the time, but of course not everything. We'll never know everything. Evidence that we know a good bit about predicting eruptions is that no one was killed by volcanic eruption last year except for a few hikers who ignored warnings to stay out of the danger zone.
Pedantry Alert 🚨 GH - in the opening sentence either say “as of ” or say “currently” - but using them both not only sounds weird…it’s at best redundant (if that sentence is heard on the date you mention), and at worst it’s actually incorrect (if heard *after* the date you mention).

Would dropping a bunker buster deep penetrating bomb on IWOJIMA 's cadera (with Japan's permission) cause the volcano to erupt those types of munitions are 2000 pounds, I like penetrating bombs, these usually are used on 50 story deep military installations but may not be powerful enough to open a volcano, I wanted to know since I was young.
Planetary alignments don't have a significant impact. The amount of stress caused by such alignments is far less than that of the tides. And even tides don't cause eruptions (although they can influence the timing of eruptions that are likely to happen anyway).
@info-m8p. Since when is it your right to tell anyone with autism, speech impediment etc that they may not use their own voice in your Aryan vision of TH-cam, even in their own channel?
The rising of Iwo Jima has exposed many remnants of the terrible battle there, ships and other things are now above water level.
Very interesting...thank you
There really has been a surprising amount of uplift since 1945. Quite dramatic.
My dad was on Iwo day 3-4 I think as a signalman quite the history there!
Many many shredded personnel carriers I'm sure (Amtraks?)

That +/- erupting volcanoes list is a really awesome idea, love it
Excellent content as usual.
well that was an interesting series of activities

Yes, there are 50 volcanos erupting. No, it isnt particularly unusual and no, it has nothing to do with the solar maximum, sun flares, or the Aurora.
True.
What about Biorythms??? 😂😂😂

Rainfall is usually measured in millimeters. 1mm on one square meter = 1 Liter.
Tobaru. Never heard of it until now.

Rainfall there at Mayon Volcano is frequent. I remember when we visited that area, most of the time it is covered by rainclouds.
Great video! Where is it possible to access real-time ground deformation/seismic data?

Properly better than that.
It’s farther from the water so probably not

How timely as I just started Eruption by Michael Crichton.
Does lack of volcano eruptions all over this planet RPS 111

Since the planet is cooling (over billions of years not in humans life times) will the planet eventually not have as many volcanoes and earthquakes?
