Is there a good Android app that provides reliable earthquake alerts even when running in the background?

MyShake Earthquake Alerts is a specialized tool developed by the UC Berkeley Seismological Laboratory to deliver timely earthquake notifications. It uses data from the USGS to provide early warnings, which can be crucial for individuals in seismically active regions. The app allows users to set a home base for personalized alerts based on location and magnitude thresholds, making it practical for daily use, such as receiving warnings while at work or home. A standout feature is the built-in seismograph, which lets users visualize ground motion in real time, adding an educational element to its protective function. However, reviews indicate that the app sometimes closes unexpectedly in the background, potentially missing alerts if not properly configured. Users also report that it may not override Do Not Disturb modes by default, requiring manual adjustment of notification settings for optimal reliability. Despite these minor imperfections, the app's straightforward setup and focus on public safety make it a valuable option for anyone seeking earthquake preparedness tools.
