Android phones turn into seismometers thanks to a new system from Google
Google launches a new earthquake alert system on Android phones in India, aiming to provide early warnings to users in case of an earthquake. The system relies on using motion sensors in smartphones, which can act as small seismometers.
How does the system work?
The system uses a network of mobile phones that share sensor data with Google, where Google’s server analyzes this data and determines the location and size of the earthquake. The system sends alerts to users in the earthquake area, with guidance on the actions that need to be taken to ensure safety. The alerts are classified according to the level of risk, where the alert is issued on the user’s screen and a loud sound in case of strong earthquakes, or on the user’s screen only in case of weaker earthquakes. The alerts are sent in local Indian languages that are supported by Android phones, and include phrases such as “Be aware” or “Take action”.
What is the benefit of the system?
The system aims to provide early warnings for earthquakes, which may help save lives and reduce material damage. The system contributes to increasing awareness of earthquakes and preventive measures, and enhancing the culture of disaster response. The system benefits from the power of Android phone network, which covers millions of users across India.
What are the requirements for using the system?
The user needs a smart phone that runs on one of Android 5 or later operating systems. The user needs a Wi-Fi connection or a cellular data connection. The user does not need to install any special application, as the system works as part of the operating system.
Can the system be used in other areas?
Yes, the system can be used in other areas, as Google is working to expand its scope to include most countries by 2022. Currently, the system is available in several countries, such as the United States, Greece, New Zealand, Turkey, the Philippines and some Central Asian countries.

Does Google’s system intelligently identify the sources of earthquakes?
Yes, Google’s system intelligently identifies the sources of earthquakes, using artificial intelligence and cloud computing. According to Google’s blog, the system analyzes the sensor data sent by Android phones from different regions, and determines the location and size of the earthquake with high accuracy. The system also benefits from the ShakeAlert network, which uses more than 700 seismometers installed in California, to send fast alerts to users in this state. In this way, Google’s system precedes the speed of earthquakes by the speed of light, and provides users with valuable seconds to take the necessary actions to protect themselves and their loved ones.
