For those of you who didn't grow up in earthquake country, some tips: DO NOT get into a doorway, that's a myth. It's not a terrible place to be if it's a doorless frame, but if there is a door, it's more likely you get injured from the door smacking you than the earthquake. DO get under a strong table. That's the safest place to be in a quake if it happens when you are indoors. If you're outside get as far away from…

You forgot the advice of "don't run outside from a building." In the US, most buildings are going to be fine structurally; however, the facade of the building or glass, etc., may fall off. In other parts of the world, it'll depend on the local building codes and their enforcement.

The scaffolding-covered sidewalks in front of many buildings in NYC are a good reminder of that actually. I wouldn't trust the scaffolding to protect me if major parts of a building were to fall off in an earthquake however...

Curious about the 4.7 vs 4.8. Official source here says 4.8 but title says 4.7. APNews did something similar showing 4.8 in the headline but 4.7 in the text. Coincidentally the depth is 4.7 km. Wonder if there's just a transpose error and a lot of copy/paste.

I've been watching USGS since I felt it. It was originally 4.8, then it was 4.7 for a little bit, and they brought it back up to 4.8.

That helps. I must've just missed it when it said 4.7. Most articles just state 4.7 (or 4.8) though a few are now saying "preliminary magnitude of 4.7." By the time I saw it, it said M 4.8 mwr with uncertainty ± 0.0.

Also interesting is the list of two "catalogs" with mostly similar data but very different depth reports: https://earthquake.usgs.gov/earthquakes/eventpage/us7000ma74...

Earlier quoted context omitted.

It's relatively self-explanatory. The full expansion would be " Duck under a table or other rigid object. Cover your head. Hold on."

Yeah no, unless someone has previously told you what it means there's no way of guessing that, that's just wishful thinking.

I bet you’ll remember it now though :)

It really isn't for anyone whose native language is American English. Unless you plan to quack, while singing a Mariah Carey song, and waiting to speak to customer service rep instead.

I felt that (I live on Long Island). I thought it was construction vehicles. We've had a lot of heavy construction around here. What made it clear it was different, was my cat didn't like it, and he ignores the construction.

Speaking of cats and earthquakes, I just watched: https://www.youtube.com/watch?v=VJ-p9qOhBv4 ...again. This is a Cat Cafe in Japan, and you can clearly see the cats get alerted to something ~10 seconds before the shaking starts. Do we have an idea of what they are reacting to?

They are feeling the p-wave, which arrives just before the s-wave that you feel as shaking: https://www.smithsonianmag.com/smithsonian-institution/ask-s...
