How long do these earthquakes typically take until they are over?

> The 1989 earthquake in Loma Prieta, California, which killed sixty-three people and caused six billion dollars’ worth of damage, lasted about fifteen seconds and had a magnitude of 6.9. A thirty-second earthquake generally has a magnitude in the mid-sevens. A minute-long quake is in the high sevens, a two-minute quake has entered the eights, and a three-minute quake is in the high eights. By four minutes, an earthquake has hit magnitude 9.0.

Evangelion is their Star Wars, at least in terms of merchandising and cultural references. I think I heard somewhere that it's known more for the pachinko machines than the actual media

How can any show with the beginning scene of the “end of evangelion” be the Star Wars or anything? Luke skywalker didn’t feel the need to choke his chicken to a knocked out Leia, but this is exactly what shinji does in the first scene of the end of evangelion.

Japan, that's how. Also, I'm not sure everyone who recognises Evangelion in Japan has actually watched more than the anime or rebuilds. A whole lot of people just know it as the logo on the pachinko machine

Was in Tokyo today, if I didn't see the news, I wouldn't have noticed there even was an earthquake. Surprised others said they felt it.

Didn’t feel it either, and my family and I are close to Shirokanedai. I hope folks are fine where this was felt more than what I experienced.

For people unfamiliar wanting an easier comparison, Evangelion is Japans star wars. It'd be like learning of tornadoes from someone with Empire insignia

Evangelion is so mega overrated of an anime im experiencing second hand embarrassment on behalf of Japan for letting its national personaification be exlempified by shinji.

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

Depends on the location, the alert comes usually as soon as the initial tremors are registered. If you're at the epicenter, tough luck. For example, for me in Tokyo, the alert came 2 minutes before it hit, and even then, the actual earthquake was extremely subtle.

In our case I guess we got the warning 10~20 seconds before the earthquake? I don't know, I didn't count it xD

I use NERV, it gives you a countdown timer and i like to know whether to prepare or not

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.

That would include Apple and Google.

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 pick up Ghibli films more please Japan.

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.

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.

I was in a chat with people in NYC when it hit. They got advance notice, although it was just “why is everything shaking?” Followed by me going silent for a bit, so they didn’t know what was going on until it reached them.

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.

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.
