Google launches Android Earthquake Alerts System in PH
The system uses accelerometers in active Android smartphones to detect seismic activities. It alerts people in two ways — via Search and directly on the Android mobile device itself. The system provides near-instant information to Google Search. When people look up “earthquake” or “earthquake near me,” they will find relevant results, along with helpful resources on what to do after an earthquake. On the other hand, the Android device notification provides an early warning alert when accelerometers detect an earthquake in an area. It sends a signal to Google’s earthquake detection server, along with a coarse location of where the shaking occurred. The server then takes this information from many phones to analyze if an earthquake is happening, where it is, and its corresponding magnitude. People who do not wish to receive these alerts can turn it off in device settings. On mobile devices, the Android Earthquake Alerts System displays two types of alerts, depending on the magnitude and intensity of the earthquake. Be Aware alerts people when earthquakes with a magnitude of 4.5 occur, or an intensity level of 3 or 4 on the MMI scale. The notification is sent along with the distance of the earthquake's epicenter. The alert uses the phone’s current volume, vibration, and Do Not Disturb settings. Take Action is a full-screen alert for earthquakes with a magnitude higher than 4.5, or an intensity level of 5 and above on the MMI scale. To help people prepare for potential heavy shaking, full-screen instructions are shown and the phone plays a loud sound.
