By 2022, Google will release the Earthquake Alerts Android app with an Android software update.
It is a system that will automatically detect the oscillations of the accelerometer of each smartphone, to generate warnings on the initial phases of an earthquake.
The platform will therefore treasure the nearly 3 billion Android devices active all over the world to create anonymous graphs of how the earth's layers move, alerting in the event of waves exceeding the danger threshold.
According to the scientists working on the function, it will be possible to warn users at the first hint of 'P' waves, called primary because they are the first to be felt during an earthquake and already analyzed in particularly seismic areas, in order to secure the population before the eventual 'S' wave, slower but also more fearful. Google has already launched Android Earthquake Alerts in beta testing in the United States, Greece, New Zealand, Kazakhstan, the Kyrgyz Republic, the Philippines, Tajikistan, Turkey, Turkmenistan and Uzbekistan. The stated goal is to create the "largest earthquake detection network in the world".
On Android phones, alerts will be sent as a notification with visual indications on how to proceed, from taking cover to holding on to something while the earthquake occurs. At any time, these notifications can be disabled by going to the device settings. As in California, where the giant collaborates with the United States Geological Survey and the California Office of Emergency Services, it is plausible that the platform will preferentially communicate with the competent critical bodies in each country in the process of being activated.
