As a LA resident, this could be a must-have app. Sadly, it seems designed by individuals with no experience in even basic app design, or they do not do even the most basic beta testing, rendering it worse than useless because it just doesn’t provide alerts. After the recent set of earthquakes (where no one received alerts on the app), they revised the app. Still wont work: * If you click “provide feedback” in the support section of the app, it takes you to a USGS site that has interesting information but absolutely no place for feedback. This is a real gap in enabling feedback. The app needs to provide proper contact information. * If you travel, the app follows your location and only provides earthquake information for where you are physically located at that moment. We want to know information about where we live in SoCal all the time. Instead, we receive information about San Francisco, Washington DC, Dallas, Chicago, London, or wherever we are traveling. This makes the app useless. The app needs to be able to have a “home” setting. The solutions to both of these are very easy fixes, and would greatly improve the app’s utility.

I fully support the idea of this app. We need it. You should download it now. This post is to provide feedback to make it better. The success of the app requires users to be taught what to look for when an alert comes in. There is no demo. Is there a sound played, like Amber Alerts? Or, the national emergency tones played on Radio and TV? Is there a notification shown on the lock screen? Will that notification and alert sound be played even if the device’s do not disturb function is on? Unfortunately, we have no way of knowing. I even scoured the internet and couldn’t find any examples of this thing being tested. Recommend that a demo video be added teaching uses what to look and listen for when the alert is triggered. I also recommend providing instructions about how to make sure the alerts are seen/heard...such as avoiding do not disturb and setting location services to “always on.” Until then, I am praying any alerts that come are able to be seen and heard...and that I can figure out that it is a serious alert and not yet another annoying news app notification about Trump’s dumb tweets.

This app is a great idea and I am glad to see it finally get released. I haven’t experienced any problems or crashing and it’s brand new so nobody can say much about its efficacy yet but I hope it succeeds one day to do what it was created to do; save lives. Los Angeles is the first city to have an earthquake early warning tool like this one. We all know there will be earthquakes in this city, maybe not today, but it will happen. There’s no good reason not to be as prepared as you can and this app is a good place to start. This app includes a few simple tools for earthquake preparation like checklists and helpful instructions about what to do during and after an earthquake.

I just got this app hoping it works as advertised. I’d like to request an update based on the other reviews and descriptions that I’ve read. Part of the requirement for this app to work is that my phone must be located in LA county and location services must be Always On. Well I live in LA county with my family but my profession is a corporate pilot. I travel the world and I personally am not always in LA county but when there is a danger to my family, I want to know about it ASAP!! Case in point, this recent Searles Vally Quake. I’m currently in the UK and did not find out it was going on till 3.5 hrs later. It’s tough being away from home and I want to know about any potential danger at home as soon as possible. I don’t see why MY phone has to be in LA county for me to get the warnings. I’m sure there are many others that are in s similar situation. I want to know about all earthquakes in LA county weather I’m there or not! From the news feed I’ve seen, I also think the trigger threshold should be lowered. I you can feel it in LA County, I think I should get an alert as well. Thank you for your consideration!

Los Angeles felt the effects of two large quakes that happened 100 miles outside of L.A. July 4-5. There was no cause to be notified in L.A. County because the potential damage caused by these quakes were only expected to happen outside of the County. The app was designed to only alert folks living within L.A. County IF damage or potential injury was imminent here. The fewer alerts we get, the better, because when those few alerts DO come thru you know it’s gonna be Northridge all over again, in which case those precious seconds to remediate come into play, which was and is the point to this app. Disclaimer: I’m just some random L.A. citizen.

ShakeAlertLA alerts you that an earthquake has been detected and that you may soon feel shaking.

You can also use this app to prepare for an earthquake, get details on recent earthquakes, and find help after an earthquake. This app is brought to you by Mayor Eric Garcetti and the City of Los Angeles, and built on the ShakeAlert system developed by the U.S. Geological Survey.

Version 1.1 adds a new feature based on feedback from the ShakeAlertLA community. The "Recent earthquakes" screen now displays earthquakes of magnitude 3.0 and above in the past 30 days for the continental United States.
