Felt it all the way in Tokyo!
There is this amazing app called NERV that, whenever there is a large earthquake anywhere in Japan, sends you an early warning push notification and an animated display with shockwaves emanating from the epicenter, plus a countdown timer for the first wave hitting you. The first it went off for me it felt like something out of sci-fi. I think I got 45 seconds this time before my apartment started shaking.

Does it play appropriate Evangelion OST track depending on magnitude though?
It is straight up the same NERV, so it might.
From the site:

This is just the best. A very serious company, doing seriously cool and important stuff, also has an anime name/icon.
I wish more corps took themselves so lightly, while remaining serious about what they do.

45 seconds is an incredible accomplishment. That’s a decent amount of heads up to get safer place. Obviously nerve wracking but great progress in alerts
Earthquake early warning systems are a top 10 peak human achievement in my book. No joke, I tear up watching videos of Japan's EEW system alerting people of possible danger just in time.
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 :')

This clip always gets me:

It sounds impressive but it's worth considering that this was a large quake that was felt by basically half of the country. You do not get this much warning if you are anywhere near where damage happens.
The 45 seconds is better thought of as the time it takes for the quake to propagate to Tokyo
Yeah. That's leagues better than what I get in Taiwan. The alert often arrives when the building is shaking or even after. I've never had a meaningful headstart.
I usually get it a few seconds ahead of time at least, in Taipei. I figured it's more related to the proximity than anything else.
It would seem the forewarning depends a lot on the distance from the epicentre. This quake, for Tokyoites, was far enough from them that they could beat the earthquake's speed. I'm fairly certain the people on the East Coast near the quake got no notification ahead of the event.

An Earthquake happened in SF recently where I got a push notification from Apple/iOS and I felt it maybe 5-10 seconds later. Nothing fancy though just a notification. I'm guessing it's not on for Japan? Seems like this app shows way more.
For big enough quakes you get notification from the government (a VERY loud and specific one too, being in public and hearing _everyones_ phones suddenly go off is... mildly terrifying) too; but they're so frequent and (usually) non-super-threatening that they don't get sent out for _every_ quake.
"not on for japan?" Are you expecting to have gotten a notification in SF for an earthquake in a place a 12 hour flight away? That sounds like annoyance, not a feature.
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’s 100-300 earthquakes/week in California so MyShake prefers to only warn for the bigger ones.

I was asking if this feature is turned on in iOS for Japan residents for earthquakes in Japan.

How do you use your 45 seconds?
At 45 seconds, load up social media. (although I actually missed the warnings this time, was focused on work) At least assuming the number is only 7.x.
If it were 8+ or somewhat closer, I'd get under my desk. (then pull up social media on my phone)
Standing underneath a doorframe is also advisable.

If it's a big one and it's near you, you'd move away from the windows and heavy things that can fall, I suppose?
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.
We do - gave me a few second warning of a 4-point one a month or so ago

If you are in a precarious position at the time 45 seconds can make all the difference a California resident.

Stop any trains. Open elevators at nearest floor.
Stop all surgeries if that is a thing you do. Stop doing any delicate hygiene routines if you happen to be in the middle of one.
I didn't feel a thing a bit south of Nagoya. Almost strange that there was nothing here, when you got shaking in Tokyo.
Receiving one of those sounds really scary.
Hmm, why does this needs to be an app and not the built-in alert notification system? Outsourcing critical infrastructure and emergency services to private parties is always a terrible idea.
> Outsourcing critical infrastructure and emergency services to private parties is always a terrible idea.
That would include Apple and Google.
In California I was recently alerted to a quake both by iOS (government issued alert) and the MyShakes app.
For major quakes I think over communication is probably warranted.
In many countries the authority and capability to send alerts is relatively decentralized and/or they require people to be inserted in the decision loop. Things are this way for policy and jurisdictional reasons. To change it you'd need to redesign the bureaucracy and authority, including many parts that have nothing to do with emergency services. Those changes are not going to happen.
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.
There's things built into iOS and Android and the government does send them; but not for _every_ quake, only for the bigger ones, and if you're close to epicenter.
This wasn't big enough in Tokyo to send out one.

How many stories above the ground, and might you guess at your building's construction (wood frame, steel frame, etc.) and foundations (on bedrock, on loose sediments, etc.)?
