This function is often based on an accelerator used to determine changes in the movement and direction of the device to provide speed and automatic conversion fixing. In smartphones, accelers that measure acceleration along the three axes are mounted: horizontal, vertically, depth. It collects data from smartphones to detect the warning system and seismic activity from Google, from Google to Earthquakes.
According to Android authority observers, the accelerator may also determine the vibrations of the soil during earthquake. Together, these data and the user’s approximate geographical position, to verify the reality of the earthquake and to determine the location and size of the region to determine the earthquakes that analyze data from many phones are sent to Google servers.
In the last four years, the system has recorded more than 18,000 earthquakes and warned that “millions of people in almost 100 countries”. Users receive a warning at least 15 seconds before the beginning of the earthquake, closest to the central base, within about one minute. This increases the chance and gives at least some rates to take precautions.
This function appeared in Android in 2020, and in September 2024, Google expanded its impact on all US states. In addition, earthquakes have recently emerged in Wear OS for smart watches.
