There are streamers who's whole thing is watching these alerts and setting up bobbleheads and glasses of water and stuff to show the shaking. It's so so so cool. Look at what we can do for each other you guys :')

The 45 seconds is better thought of as the time it takes for the quake to propagate to Tokyo

The broadcast warning from Japanese equivalent of NOAA don't get issued to areas where the peak acceleration is expected to be less than Shindo 4 level. So GP probably had 3 or less.

Shindo is peak and Magnitude is an integral, so these two can be wildly apart, and Shindo is more commonly used in Japan since buildings tend to be more resistant to longer events with lower peak intensity.

We also have the MyShake app here in CA, but I don't recall getting a notification through it for the last quake. I was asleep, though, so my memory is hazy.

There is actually a clear, concise and actionable answer to this question:

- Hide under the nearest table or desk (if you are at home or in the office).

- Grab the nearest pole or handrail (if you are on a train).

The basic idea is that the most common cause of death in an earthquake is being crushed by falling objects, so you should use every second to minimize the risk.

Here are a few common mistakes:

- Do not attempt to stop furniture from falling (you'll get crushed by it)

- Do not try to run outside (you'll get hurt by falling walls)

- Do not try to turn off the gas (most systems have automatic shutoffs)

- And for Catfish's sake, do not use your precious 45 seconds to open the social media.

If it were 8+ or somewhat closer, I'd get under my desk. (then pull up social media on my phone)

For me I always just turn on iPhone screen recording and marvel at this amazing app and wish we had something like this in California.

This wasn't big enough in Tokyo to send out one.

That would include Apple and Google.

Under these constraints it is effectively impossible to send automated alerts at scale with low latency as demonstrated here. A private app does not operate under such constraints.

For major quakes I think over communication is probably warranted.

Anyway, in the case of Cascadia, remember that the lack of big earthquakes over the past 100 years is probably telling you that we just happen to live in a time where strain is accumulating (D:)

Why did Mongo have an "EARTH QUAKE" button on his spaceship control console? Did he have buttons with the names of all the other obscure bodies he encountered, too?
