The data of accelerometers in Android smartphones will be used for the early detection of earthquakes. As announced by Google, the smartphone will be send to the server a signal, after which people will get an electronic notification.
The earthquake consists of the seismic waves, the first of them to reach the earth’s surface P wave. To learn more about help the earthquake observation stations with high-precision seismographs. But the time for warning the population, usually a bit.
To help solve the problem of a special application for smartphones that analyses the readings of the accelerometer and if you suspect the beginning of the earthquake can send a signal about it to the server. Within six months the system has detected more than 400 earthquakes. But it has a drawback – the smartphone owner needs to install the program on their own, while not all users even know that it exists.
In this regard, Google has implemented algorithms that detect seismic waves directly into the Android operating system. First, smartphones will continue to collect data and send them to the server, and users will be able to see on the search query of the earthquake, when and where it is possible.
In the case when a lot of smartphones in one area will find similar to P – or S-wave, Google will send users a notification with instructions on what steps need to be taken to safety. Conditions – at this point, the smartphone needs to be charged and the system operates only when enabled on the device functions "Geolocation Google" in the settings.
The company is already working with the system warnings about earthquakes in California.
