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.
More information and a tutorial is at https://earthquake.lacity.org/shakealertla.
This version allows for notifications to be sent when an earthquake creates a magnitude 4.5 and intensity shaking (MMI) III in Los Angeles County. Notifications of earthquakes of larger magnitude outside of Los Angeles County will only include notifications if the magnitude and shaking is felt at these levels in LA County. Universal Time Coordinated (UTC) time has also been converted to show Pacific Standard Time (PST).
Ratings and Reviews
Great idea, poor execution
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.
Good potential...there yet? No way to know.
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.
Not sure why people being so negative
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.
Developer Response ,
MonstrCoco, thanks so much for helping to clarify the idea behind the app. It's great to have folks really see the possibility in how an earthquake early warning can make a difference.
