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.
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.
I have rarely seen something as scary as this.
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.
0.7m observed about 40 minutes ago.
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.
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.
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.
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?
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.
It is a transferable skill. Have tried ice skating twice, could just do it fine.
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.
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.
The damage was huge.
https://www.usgs.gov/faqs/what-probability-earthquake-a-fore... Suggests 5% for larger quake to follow within week. But overall most sources I could find suggested it's hard to know, needs more research

(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.
Myth 5 is "Small Earthquakes Relieve Pressure and Prevent Larger Ones"
So the only thing we can say for sure is that it is still extremely difficult to predict earthquakes.
> 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.
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.
Shouldn't be too bad; USGS forecasts up to 1 meter tsunami.

What is a typical maximum wave height during hurricane seasons in north of japan?
WRT comparison with hurricane waves, I assume they carry a lot less energy than tsunami's, because they are "superficial waves" - caused by the friction of the wind on the water - whereas a tsunami wave is caused by the movement of a huge mass of mater.

(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.)

My predictions:
Actual zombie president in 2044.
New COVID in 2061.
Dinosaurs come back in 2123, reveal they've been steadily populating hidden Nazi underground bunkers and have declared peace with the yeti.
I guess we'll know, soon.
This all happens in geologic slow motion, of course.
