Today I got served this video "Earthquake and Liquefaction his Urayasu, Chiba 3/11/2011" [0], which is from the earthquake which caused the huge tsunami in Japan.
The flood videos of towns, cars, and people being violently washed away are way scarier IMO.
Urayasu looks built on the water and all I see in the linked video is a threshold condition where the water is just barely peeking up through the ground below. People are still walking around, cars driving. There are far more chaotic and destructive scenes on youtube from that tsunami.
Was in a hotel in Sapporo, almost got thrown out of bed. Lot of people in the hotel lobby now.
Considering leaving Hokkaido by air if a Hokkaido and Sanriku Subsequent Earthquake Advisory is issued, don't really want to be in a potential megaquake.
Good luck, the Sapporo Chitose airport is closed for inspection of both runways.
BTW, you are safer in hotel than outside. No need to stay in lobby, go to bed, just protect your head. I experienced much bigger one in Sapporo in 2018.
When I was in japan the earthquakes were oddly exciting rather than scary, had three different ones while I was there that visibly shook rather heavy objects around. Two being in a building and one outside.
It was rather interesting seeing things shift around leaving a permanent imprint that there was in-fact an earthquake and it wasn't some kind of illusion when earthquakes these size couple of decades ago would cause non zero amount of damage.
Although, I am scared for tokyo about the predicted earthquake that would push all these systems near the breaking point and even beyond it, but hopefully the past in not prediction of the feature and instead it'll just be a lot of smaller earthquakes.
Funny, I had the exact opposite reaction. Things I had taken for granted all my life suddenly became un-anchored and as a result so did I. I have never felt an actual feeling of panic that threatened to overwhelm me before that happened and it was a very mild earthquake. I had to really force myself to calm down and stay rational and do what was the safest rather than to give in to the 'flee' reflex.
The problem with earthquakes is when they start you know you're in one but you have no idea where you're headed, whether this is as bad as it gets or whether you're going to end up in a pile of collapsed rubble and what is the best decision greatly hinges on something you can't know ahead of time, which is the peak magnitude and the kind of earthquake you are experiencing.
> Things I had taken for granted all my life suddenly became un-anchored and as a result so did I.
Same for me. If you don’t grow up with a number of small regular quakes or live in high-rise building that sways with the wind, it’s pretty unsettling to feel, what you always know as stable hard ground, solid buildings all of the sudden bouncing around. Rationally you know what it is and how it works but it’s still scary.
99% of your problem can be solved by studying statistics for your area, and having a plan... So that you aren't just at the whims of the moment when it's actually happening.
What kinds of statistics is it that one should study?
Having a bugout bag and emergency supplies and water on hand is a reasonable idea everyone with the means ought to do; it's a good thing to not have to depend on gov't intervention (not because of a lack of trust, but because the general public will, and the potential for mob situations is high).
But what should I have read about to know what to do? Topological maps and flood planes?
I always was in one of the major cities so I had full confidence in them. Lacking the natural fear of death probably has something to do with it as well.
What seems to matter greatly how affect someone is by an earthquake, seems to also be related to how used people are to being unbalanced. I was once with a group of friends who most of them were skaters and snowboarders, so used to thinking about balance and being in situations where they can't do much about it, standing on relatively unbalanced things. During the earthquake, similarly to parent, most of them were fascinated, while the non-skaters quickly panicked and threw themselves on the ground.
Of course, just an anecdote, and those people could also have a general lack of fear of death, but the difference between the two of you made me think of the event again.
Well you actually bring up a very good point, people who do extreme things know full well that one mistake and they can hit their head and never walk again, feeling the same fear while knowing that you are not in any danger is what creates excitement in a way.
This would be the tenth major earthquake (7+ magnitude) along the Pacific ring of fire this year.
With the Kamchatka and other earthquakes in the news recently I had a fear that were building to some major event but turns out that this year is about average if not slightly below average for major quakes along the ring of fire.
I heard that smaller (relative) earthquakes actually lower the prob of larger ones, so maybe it is a good thing? A bunch of 7.X earthquakes in the ocean are not going to be hugely destructive.
> A bunch of 7.X earthquakes in the ocean are not going to be hugely destructive.
New Zealand’s 5th most deadly disaster was Christchurch’s 6.2 which killed 185 people. It was a shallow aftershock from a larger, less destructive quake.
That's correct, if relatively small earthquakes would stop that could be the precursor to a much bigger one. It's like releasing tension gradually rather than all at once.
(stresses build up and are often released through many small, unfelt earthquakes (25:54). If these small movements don't dissipate the stress, it can accumulate and lead to a powerful chain reaction (26:25) * disclaimer I used YouTube's built-in AI to find/summarize the timestamps, as I couldn't remember offhand where it was when I previously watched this.
> The Japanese government set up a task force at the crisis management center in the prime minister's office at 11:16 p.m. on Monday in response to the earthquake.
A thousand Naruto shadow-clones just got deployed. I'm not being cute, these guys are heroes and role-models to all.
(Thanks for the link - we've since merged the threads to a submission of that one. I've included the other major links that people have been posting in the toptext.)
I assume that movie is for Japanese civil servants like the show Silicon Valley is for programmers. Stuff like the repeated meeting-room changes for no apparent reason reads as too specific and weird to be made-up.
Somewhat offtopic curiosity: Is there anything that Japanese fishkeepers do to keep the water and livestock inside the tank during earthquakes? Here we have no such risk for earthquakes, so a 600lb tank of water 4ft off the ground isn't much of an issue, even when bumped. I'd imagine earthquakes of this frequency could complicate that.
Is 1 meter bad? In context it seems to be missing what kind of waves normally hit the coast line, and what kind tide differences exist, and what the current water level is when the wave hit.
What is a typical maximum wave height during hurricane seasons in north of japan?
Your comment prompted me to go read about epicenters and I learned something new. The hypocenter of an earthquake is apparently the point of origin of the earthquake and the epicenter is the point on the earth's surface directly above the hypocenter. Had never heard of a hypocenter before.
I didn't know about hypocenter before too but it's neat how you can sometimes deduce the meaning of a word from its parts (because "hypo" means "under"/"below" in Greek, like in hypodermic, hypoglycaemia, etc).
The class wasn't as interesting as I'd hoped, in part because it seemed to attract older kids hoping for an easy grade, but in my high school we had an etymology class.
(My school also offered Latin, but etymology seemed a much more direct/easier way to get the same basics. I just wish someone had taught me about demographics so I would have taken Spanish instead of German.)

To think that these are happening more and more around the world and the USA just lost 9 detection stations near Alaska because of NOAA budget cuts. There was also the giant tsunami in the middle of nowhere this year.
Does anyone else find the way of using tsunami.gov totally baffling? It tells the user almost nothing, and the target of all the hrefs for the supposed messages listed in the map is just the tsunami.gov homepage again. The entire above-the-fold is occupied by the map, and the map tells the user nothing.
It has recently been a 4th degree one at Vitoria-Gasteiz, in the North of Spain. One of the least probable places you would even think of have an earthquake...
I have rarely seen something as scary as this.
