Android Users Alerted Just Before California Earthquake (axios.com) 47

While many people in California felt a moderate earthquake Tuesday, some smartphone users actually got a heads-up before it happened thanks to technology developed at the University of California, Berkeley. Axios reports: Researchers at Berkeley released an app called MyShake that can offer a brief earthquake warning by detecting the signals of an earthquake just before they are felt. Think of it like how you can see lightning before you hear thunder. The app works on both iPhone and Android, but Google announced in 2020 it would implement Berkeley's technology directly into Android, allowing far more people to benefit.

As often happens after an earthquake, people turned to Twitter after the Magnitude 5.1 quake. But some reported getting the alert first. "Got the earthquake alert on my Android phone a few seconds before I felt it," Google's Dieter Bohn said in a tweet. Google CEO Sundar Pichai also tweeted about getting the alert.

    I live in Japan and have for the last 12 years. I was there for the 2011 quake, and following the quake, this functionality was available in all Android and iPhones natively, with no need for an app. I get alerts fairly regularly just before a fairly sizable quake hits now.

    • This is different, and is using phones as seismometers to help predict earthquakes. The US already has the Emergency Alert System, which is on all phones, and can send any notification the government wants to send. So technically they can already alert anyone they want of anything they want, such as an earthquake.

      MyShake involves accelerometer and GPS location data collection, processing and transmission, in addition to displaying alerts.

      In Southern California during the 1980s and 1990, so 40 years ago, one could listen to the W6FXN repeater which would transmit the Running Springs seismic tone if a certain deviation was exceeded. Depending on the geometry, this would provide several seconds of warning.

    It came afterwards for most people who were near the epicenter (who it matters for). And then by coincidence an Amber alert came a short while later which confused some people too.

    • It will never be possible to alert people in any reasonable time when they are close to the epicenter. For a quake of this magnitude the service is more of a curiosity. When you get up to 7.0 and greater is where an app like this can really shine. People right near the center will still be surprised, but people a considerable distance away will get several or more critical seconds of warning to take cover. Quakes of that magnitude can cause damage far from the epicenter. This app can save lives in that

      That can happen on phones where the manufacturer made the power saving too aggressive. Certain services, like the one that handles push notifications and these alerts, is not supposed to get power managed to death so that it can promptly deliver messages.

      I've used this feature in Japan and the alerts consistently arrive before the earthquake is felt.

    That's called bloat, especially when you consider what a small percentage of the population live in earthquake zones. MyShake only supports three states in the first place (California, Oregon, and Washington). But let's just put it on a billion Android phones anyway.

        Right... because there are only 10 states that even have an earthquake index greater than 1.
        To round out the bottom 16, these don't even have an earthquake index of 0.1 (California's index is 200 times higher, at 21.8, which is 5 times higher than the next continental state)

      One man's bloat is another's critical feature. I'm happy for you that you don't need or want to use this but really confused as to why you think that general purposes OS are designed specifically for you and only you. I mean every man thinks they are the centre of the universe, but most of us don't go nearly that far.

        One man's bloat is another's critical feature.

        I think that's why many devices nowadays have the ability to install additional software on top of the factory image. People for whom a feature is critical can install it.

        Or maybe, as an intermediate between the extremes, bloaty features can be included by default in factory images for high-risk markets (e.g. Pacific rim, central Asia) and not in factory images for low-risk markets (e.g. Europe, Africa, rest of the Americas).

      The P-waves seem like they're good enough of a hint by themselves, assuming the building you are in isn't big enough for them to get absorbed.

      You'd have to be a pretty good distance away for an alert to arrive sooner with the p-waves traveling at ~3.7 miles per second. Figure two or three seconds to detect the event, then a two or three more seconds to broadcast the notification, and you're at probably 20 to 30 miles before the notification would beat the actual arrival of the P-waves.

      At 20 miles, I felt t

      I got the notice on my phone. I'd never seen that before, so I picked the phone up to read it. I felt the movement a couple of seconds later. I was about 25 miles / 40km from the epicenter. This was the first notice I'd ever received, so in theory, if I recognized the alert it was enough time for me to get out of my chair and step into a doorway. It does sound like the automated responses to this sort of alert could be useful, like stopping elevators at next floor with the doors open, gas lines shut down and the one I read and thought interesting: alerting surgeons to lift their scalpels until the quake passes.
    • I had a similar recent experience with a smaller quake. First indication was felt but not immediately discernable as a passing truck versus a P-wave. Second indication was the alert, then the S- waves. I can sometimes sense the direction of arrival of the first motion, but not for that event.
  • Apple has had problems w/ its push notification system for a few years, ever since iOS 14 debuted. The MyShake App is just another one of those situations where while the app should be able to provide notifications to iOS device owners, it doesn't. A lot of apps don't run in the background anymore to save battery, push notifications being a huge consumer of idle power. Not only that but apps aren't optimized for efficiency with a push towards new features (.. that don't work) instead of reliability.

  • Yesterday I was notified via emergency alerts, similar to the way an Amber alert is delivered. And yes, I got the alert just about 1 second before I felt the shake, but it was so little of a shake that nobody else in the house felt it. Kudos to the Berkeley research team!
