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.

- kzrdude 6mo agoHow do you use your 45 seconds?
- piazz 6mo agoIf 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.
- vladgur 6mo agoWe do - gave me a few second warning of a 4-point one a month or so ago https://apps.apple.com/us/app/myshake-earthquake-alerts/id1467058529 https://apps.apple.com/us/app/myshake-earthquake-alerts/id14...
- klempner 6mo agoAt 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)
- fennecbutt 6mo agoStanding underneath a doorframe is also advisable.
- strangegecko 6mo agoI'm pretty sure that is advice from the last millennium that is no longer taught.
- fragmede 6mo agoSpecifically, the two reasons that it's no longer taught is that 1) rushing to get under a doorframe caused accidents 2) doorframes are no longer reinforced the way they used to be.
- fennecbutt 6mo agoI suppose it must be dependent on country. I'm a kiwi and that's what I was taught. We're also ring of fire dwellers.
- teiferer 6mo agoHow does loading up on social media help? Maybe turn off any gas stove, secure any dangerous tools, stop your car, that kind of thing.
- pezezin 6mo agoModern gas stoves have security sensors to turn down themselves. I had to reset my water boiler when I got home.
- klempner 6mo agoIt'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.

- gosub100 6mo agoStop any trains. Open elevators at nearest floor.
- fragmede 6mo agoStop 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.
- teiferer 6mo agoQuite clear that people here work in low risk jobs. Anybody working with heavy machinery, drills, saws, knives, etc will immediately know how to use those 45 seconsa well. Those trades that don't typically let you read HN all day.
- Danox 6mo agoIf you are in a precarious position at the time 45 seconds can make all the difference a California resident.
- cloudbonsai 6mo ago> How do you use your 45 seconds? 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.
- konart 6mo ago>NERV Does it play appropriate Evangelion OST track depending on magnitude though?
- roer 6mo agoIt is straight up the same NERV, so it might. From the site: > The name and logo of "NERV" are used with the explicit permission of khara Inc., the copyright holder of the "Evangelion" series, and Groundworks Corporation, which manages the rights to the series.
- azath92 6mo agoThis 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.
- mghackerlady 6mo agoFor people unfamiliar wanting an easier comparison, Evangelion is Japans star wars. It'd be like learning of tornadoes from someone with Empire insignia
- Der_Einzige 6mo agoEvangelion 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.
- mghackerlady 6mo agoit is a masterpiece, up there with ghost in the shell, akira, and serial experiments lain in terms of "japanese existentialist scifi"

- Aboutplants 6mo ago45 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
- deleted 6mo ago[deleted]
- strangegecko 6mo agoYeah. 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.
- sampullman 6mo agoI 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.
- philistine 6mo agoIt 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.
- wat10000 6mo agoI 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.
- prerok 6mo agoSorry? I don't get it. Why are you mentioning NYC? Was it a joke?
- Tor3 6mo agoI didn't feel a thing a bit south of Nagoya. Almost strange that there was nothing here, when you got shaking in Tokyo.
- bell-cot 6mo ago> Felt it all the way in Tokyo! 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.)?
- Xenoamorphous 6mo agoReceiving one of those sounds really scary.
- ricardobayes 6mo agoHmm, 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.
- pamcake 6mo ago> Outsourcing critical infrastructure and emergency services to private parties is always a terrible idea. That would include Apple and Google.
- jandrewrogers 6mo agoIn 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.
- klausa 6mo agoThere'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.
- spike021 6mo agoIn 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.
- pezezin 6mo agoIt is built-in, broadcasted by the cell network itself: https://en.wikipedia.org/wiki/Cell_Broadcast https://en.wikipedia.org/wiki/Cell_Broadcast https://en.wikipedia.org/wiki/Common_Alerting_Protocol https://en.wikipedia.org/wiki/Common_Alerting_Protocol
- swang 6mo agoAn 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.
- klausa 6mo agoFor 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.
- prism56 6mo agoI thought Google had leveraged on device accelerometers in a crowdsourced way to highlight and show alert anyone who will get a "rumble" soon.
- rconti 6mo ago"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.
