When will the service start?
Google has said that this service will be started in India in the next few weeks. But earthquake alert will be received only in those smartphones which run on Android 5 or later Android versions.
use of this technique
To detect earthquakes, Google’s service takes the help of ‘accelerometer’ present in Android smartphones, which can work as a mini seismometer.
This is how technology works
The blog states that when a phone is plugged in and charging, it can detect the onset of an earthquake. If multiple phones detect an earthquake-like shaking at the same time, Google servers can use this information to predict whether an earthquake may occur. After this, by estimating the center and intensity of the earthquake, an alert can be sent to Android smartphones in that area.
Google says that Internet signals travel at the speed of light. In such a situation, earthquake alert often reaches the phone several seconds before serious tremors occur. Google also said that it is working with NDMA to provide information about natural disasters like floods and cyclones in Google Search and Maps.
The special thing is that Google’s earthquake alert system has already arrived in many countries.
