- เผยแพร่เมื่อ 27 ก.ย. 2024
- Today we wrap up the first half of our series on physical geography by taking a closer look at natural hazards - which are physical processes like heat waves and cyclones, earthquakes and volcanic eruptions, and floods and droughts. And when these natural events cause significant harm to humans, we call them natural disasters. So today we'll explore the ways geographers analyze and track these events, and take a closer look at the human impact of Hurricane Katrina in New Orleans and The Boxing Day Tsunami on the Andaman and Nicobar islands.

The rules of the tsunami:
If you are at the beach, and an earthquake strikes, strong enough that you can't stand or walk normally, get away from the sea as fast as you can, toward the hills or the tallest building. Don't wait for orders or official calls.
If the quake was minor, but the waters noticeably and rapidly retire from the beach, same, and faster if possible.
Same, if the waters just retire and it's not the time for the low tide. Even more so if there are news of an earthquake in a neighboring place.
Don't stop to get your things. A tsunami can arrive in 15 minutes or even less. Some water and a blanket is all what you'll immediately need.
When in a safe place, stay there for about 8 to 24 hours. After that, whatever could happen will have happened. Before that, it might be still risky to go back.
Experience: In Chilean 2010 major earthquake and tsunami, most people in the affected coast, trusting our national instinct and lore, run to the hills. The government, at the moment badly informed about the quake's magnitude, told people there was no risk of tsunami, so they could go back to their houses. Many did. The tsunami got them.
So, with all due respect toward all elected or not elected authorities, don't go back at least for a few hours.
That was a bit of very hardly earned experience for you.
Who’s here just before an exam
I live in Mississippi and surviving Katrina was - well it was something, I can say that much. A LOT of the Southeast US has tax problems and lacks decent infrastructure, and Katrina laid that bare for the entire world to see. I think things have gotten a little better in the years since, but there's still a heck of a way to go, because the most vulnerable people are STILL in the same position they were before; there's effort to help, but it's moving a mountain with a tablespoon measure.
Great video - looking forward to Part Two of this series!
I think a lot of us in the Philippines have grown tired of the word resilience as it's used to wave away responsibilities and accountability in disaster risk reduction.
As a Natural Hazard Mitigation Officer, I really appreciate this easy way to explain what I do!
Love the dinosaur shirt!
An example of disaster preparedness - I live in Wellington, NZ - earthquake prone and recently the building I work in was closed because it had an earthquake safety assessment and failed miserably - we are all working from home now and may not see the inside of the building again until 2024 due to earthquake strengthening. All buildings in the city have to meet certain standards regarding earthquakes specifically which is pretty cool
Chilean here. A saying: "It isn't the earthquake what kills you, it's the building falling on you." An aspect not touched here regarding disaster prevention was politics/government/regulations. In Chile we are considerably less worried about earthquakes' effects because there is an strict set of regulations about building. Take that into account when voting for your next authorities. In Chile, building regulations are not even an arguable subject, but maybe where you live there can be a choosing between candidates who propose costly disaster preventive regulations and others who prefer to save that money for other investments with a more immediate benefit.
Choose wisely.
I just realised how sad I’m going to be when this series is over 😭😭
thanks for helping me with my exam
my 1st pick would be New Zealand, jungle like forests but NO SNAKES
earthquakes volcano's floods and all possible disasters but no snakes!
AP Geo here we go!!!!!!!
Want to stay in the States without having to worry all that much about natural disasters, come join us here in Michigan 😉
Can you make a music theory course please!! I love these videos and I need more
Thank you very much for this.
im biased since i live here but honestly id say the best place to live in the world is ontario canada. by extreme weather measures we only get heat waves cold waves and snowstorms which are usually not too too bad. Unlike teh states where pretty much no matter where uy live u get bad extreme weather like floods tornadoes etc. Yes u have to deal with four seasons (winter ugh) but if u want to live in a place where ur life isnt at risk by the freaking weather Ontario is the best.
That snow tho… and the cold that accompanies it… no thanks.
Ontario is full of mosquitos when the snow melts so i'm not sure, it is the best place to live, if you want to enjoy the outside.
I am Brazilian from Sao Paulo (close to Rio de Janeiro) currently living in Canada. Dude, there's no better place to live if it wasn't the shitty government. No tornados, no heat waves, not super cold days, no vulcans, no earthquakes, no wildfires smoke, water everywhere (like I can point u at least 5 spots in my neighborhood with natural water fountains), animals everywhere... anywhere in the centerish of Brazil from east to west would be a perfect choice. The only bad thing is the super high humidity that makes u sticky and thats why natives take 2-4 showers a day. The only super craaazy think is the tropical rain storms but it is only water and lightning.
I live in Florida and cat 5 hurricanes don't hurt as much as it does other states. That's if we get a cat 5, which isn't often. Other states are hurt more because lack of soil permeability. Florida is made of sand, water goes away fast so flooding doesn't usually happen outside of the coastal areas. Hurricanes cat 1-4 are usually just hunker down and have fun with your time off. Cat 5 is based on where the eye hits.
South east Canada is probably the safest place on earth in terms of geological disasters, glad I live there too.
The west coast has wildfires too. Lots of wildfires
I live in Baden Württemberg, the south-westernmost state of germany high up over the lower river valleys. The worst disaster here I am aware of during my lifetime was a storm that blew some tiles from some houses.
This is why the British Isles are a sound place to be. We basically never get anything beyond some flooding every now and then and a Gale that you would rather be inside for.
Do not even have dangerous animals. Just gotta watch out for Smackheads and Roadmen and you're safe.
this video is very educational
Why is it a hazard if its natural but not a hazard if its us, humans?
Singapore (and Malaysia) are pretty much protected by Indonesia & the Philippines from earthquake, tsunami, volcano activities & typhoon from the west, south & east. But the hot & humid climate there sucks big time.
Southern Africa experiences very few natural disasters.
Damn Human Geography is coming back. They made like 2 episodes once and then stopped and promised it would come back soon. This soon turned out to be a few years later.
I live in Cambodia. No faultlines, no volcanoes, no tornados, and Vietnam absorbs typhoons. We get some flooding in the wet season, but that's the fault of poor drainage construction.
My lord ....I have my geography test tomorrow and I was stressing about this topic and then you posted this ☺️
I live in the beautiful state of Michigan, and I’ve visited most of the Lakes, except for Superior and Lake Michigan. I love all of the states, and each one is unique to its own! There’s also many little lakes here in MI, too that are just as beautiful! But I really wanna live in either Canada or New Zealand, bc in NZ, there is so much land and animal diversity!! And I’ve already been to CA, so I know what some of it is like, and I wanna live there soooo badly! 😆
imo Superior and Michigan are the best great lakes they're on a totally different level then all of the others. admittedly I'm pretty biased tho cause I live in the UP, but still if you ever get the chance take a drive up and check them out!
I'm from Michigan!!
If you want a place free of almost all forms of natural disasters, plenty of access to fresh water, fertile soil and weather that rarely becomes extreme come to Zambia. Not only are we landlocked and far from costal regions, we are right in the middle of safe zone so no earthquakes or volcanoes. We are also the source of the Zambezi which is where the name Zambia comes from.
Note: It's pronounced Zamb-e-zi with 'e' as in egg. I see a lot of nature doccies pronounce it wrong and it irks me lol
19 seconds ago?!!!! I love your channel!!
40 minutes ago? I'm watching this in the same hour. Wow 💕 ✔ ❣.
The only place in the US that I would like to live in is the Pacific Northwest. Basically, Seattle. Everywhere else gets either way too hot in summer, way too cold in winter, or just has way too few people to be enjoyable.
The place I'm _actually_ wanting to live in is London, tbh.
What I wouldn't give for there to be flashcards on this! Love learning about Geography
I've read that Finland is the safest country from natural disasters.
I'd live in Antarctica
Beautiful but has volcanoes
SIBERIA, I def want to live an off grid, sustainable life in Siberia
The irony is that hazard etymology is chance/randomness. At some point it stop being ''bad luck'' to get hit by a natural hazard, if the same hazard happens every single year in the same region... It should be called : natural what did you expect?
Are your saying Tornado Ally isn't called that because of the rock formations? And that the people that need to rebuild every other year due to land Hurricanes isn't just random weather? Say it ain't so!!
(Love your comment if that wasn't obvious!)
It did not but it was great video and information.
Except for the certainty that there will be a large earthquake the Pacific Northwest suits me best. Next I supposed would be Indiana or Illinois. Or the Piedmont of North Carolina. Or the North Carolina mountains.
Great video what else can I say
D
Denmark, baby!
💜
NZ is the place 4me
Lake district in Uk
Roll call!
Philadelphia
Les go
👍👍👍💪💪💪
I lived in Indonesia in 2003
TIL: That rich Volcanic Soil attracts the CIA

A complex web of interactions among peoples, environments, and technologies, characterized by multiple causes and consequences?
I prefer the term omni-shambles, rolls off the tongue a little better
I'd live in the same house as you ideally
Welp waiting for ppl to freak out over this episode...😑.
Besides that good episode.
Freak out? About what? Is there something controversial in this episode? :o
Eearly:D
First.
Are u sure about that 😅

A lot of the the themes in this episode speak to social vulnerability a concept promulgated by Dr. Susan Cutter in her Hazards of place model. This was a good episode. A nice transition from physical geography to human geography. I'm more of a physical geographer but I hope human geography component is interesting in the coming weeks.
Excellent. Very informative presentation. Thank you
Fantastic series. More please.
Omg we've just finished this chapter, this video can be used for review wooo anything thx a lottt
I’ve seen every crash course series to date. I wasn’t super excited about this series due to a lack of understanding or excitement for the topic. But i can honestly say this was one of the best so far. Keep it up
This episode is poetic.
If I could live anywhere, I would probably live somewhere on the European Mediterranean coast, or that island of New Zealand that is a cockapo preserve.
I would not live in a place that will be underwater in the next century.
I’d live in Sydney even tho it’s in the ring on fire and NSW gets bush fires but cities don’t get them as there is no bush close enough. I have family there and I love the outdoor lifestyle and I’d be close 2 the surf!!!
A normal Crash Course series would've stopped here. But this one is only half way, and this is absolutely awesome!
Good video as always
Far from religious people is the place for me. But not China. Maybe Japan.
You think Japan has no religious people? What?
Japan is stifling in its own way. Replace 'religion' with the more secular 'culture', and you'll find the Japanese not too different.
Why does that even mean? Also Japan isn’t religious?
You forgot about Singapore. Singapore has no natural disasters, maybe except occasional torrential rain.
This episode launches on day we got a rare earthquake in Melbourne.
Digital Hazard can be lead by a very angry Guilmon.
I dream of Iceland...🌋❄️
I would like to be a writer for crash course ! ☺️
I love the Pacific Northwest.
The Salinas Valley is the only home that I need.
I'd want to live in San Marino
First?
Hello
First
Where would I live?
Somewhere well above sea level, so my childrens children can watch the rising sea levels flood the coastal areas, producting sea pollution nobody wants to be reaponsible for today.
who cares
