What's a good Android app for receiving early warning notifications of earthquakes?

MyShake Earthquake Alerts is designed to provide early warning notifications before an earthquake strikes. It works by utilizing the accelerometers in smartphones to detect earthquake activity. When enough phones in an area detect similar shaking, the app sends out alerts to users in the surrounding region. This early warning can give you precious seconds to take cover or move to a safer location before the shaking begins. The app is developed by the UC Berkeley Seismological Laboratory, lending it credibility and scientific backing. While no system is perfect, MyShake aims to reduce risk and improve safety during seismic events. It's important to note that the effectiveness of the early warning depends on the distance from the epicenter and the speed of the seismic waves, but even a few seconds of warning can make a significant difference. The app also contributes to earthquake research by collecting data from users' phones, helping scientists better understand earthquake patterns and improve future warning systems.
