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 apartmen…

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.

It is built-in, broadcasted by the cell network itself:

it is a masterpiece, up there with ghost in the shell, akira, and serial experiments lain in terms of "japanese existentialist scifi"

Lain is 10/10. Akira/Ghost in the Shell are great too. Evangelion is a weak 7/10 in comparison to them in every aspect imaginable. I also realized that Evangelion is Japan's version of assigning weird mysticism to religions they don't understand (much how westerners depict shinto/daoism/buddhism with tons of mysticism). Evangelion is a disgusting anime to consider part of your national personification. Drop it and pi…

> Lain is 10/10.

Caught the BeOS fan ;)

(I kid, mostly but remember Lain fans rabidly trying and espousing it)

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.

All phones with 4G/5G worldwide should have it. They managed to make the broadcast push SMS thing used for the alerts a mandatory requirement for phones.

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.

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)

How does loading up on social media help? Maybe turn off any gas stove, secure any dangerous tools, stop your car, that kind of thing.

It's not that social media helps, it's that there's not really more to do. It's just another day on the ring of fire.

In practice for anything short of the very biggest earthquakes, if you're close enough for the earthquake to truly be a big deal you're only getting a few seconds of warning. It's not a task list, it's stop doing the immediate dangerous thing you might be doing and grab immediate cover.

I live in Aomori (Northernmost prefecture of Honshu) and we got the warning before the earthquake arrived by all the cellphones in the office going crazy at the same time. It was kind of funny, because we have a lot of new guys here who have never been to Japan before and it was their first earthquake ever xD

I was just in Aomori this past week (to see the sakura blossoms in Hirosaki). We literally left Sunday night, and while it seems like there really wasn't any concern in the city, I'm not sure I would have been prepared as a visitor to the country.

I think that’s pretty much the same. NERV uses child soldiers and is secretly planning a fused hivemind. They are the Torment Nexus.

That's true, but I think the difference lies in the fact that the company using the NERV name for their product is a public disadter alert service, and doesn't seek to do or emulate anything it's named after. That's not the same for a surveillance company or a defence contractor named after the big bad of a media franchise.

If (probably bad example) FEMA started referring to its aid workers as storm troopers I'd find it a bit unsettling (actually I kind of wish they'd do that because dad jokes are the best). Similarly, while I find the reference amusing the NERV moniker doesn't exactly inspire confidence. I suppose an important difference is that they're a mixed bag rather than a purely evil organization but still.

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

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

TBF you don't need substantial structural damage for falling objects to pose a serious hazard. Plus the relationship of warning length to extent of damage depends entirely on the strength of the earthquake. For the worst ones where you need it the most the majority of the country could get a fair bit of warning.

Dude that’s fucking hilarious. Storm troopers. Amazing.
