Android phones now provide earthquake warnings in the Netherlands
Users of Android smartphones in the Netherlands can now receive alerts for earthquakes. Google has expanded its 'Android Earthquake Alerts System' to our country. This system uses the sensors in millions of phones to detect ground vibrations at high speed.
The system works by using the built-in accelerometers in Android devices. When a phone detects a vibration that resembles an earthquake, the device automatically sends a signal to Google's servers. If many phones in the same area register a vibration at the same time, the system can determine that an earthquake is occurring.
Users located near the epicenter then receive a notification on their screen. This notification provides advice on what to do, such as finding a safe place under a table or staying away from windows. Because radio signals travel faster than the vibrations of a quake, the warning can sometimes arrive a few seconds before the shaking starts.
Although the Netherlands rarely experiences very severe earthquakes, tremors in the province of Groningen caused by gas extraction can lead to damage and unrest. Google's system is intended as an additional tool for public safety. The feature is enabled by default on most Android devices, but users can check this themselves in their phone's settings.
With this new technology, the Netherlands is following an international trend in which technology is deployed for disaster prevention. While the system cannot prevent earthquakes, it does offer a valuable warning that gives people that little bit of extra time to take action.
