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 available only in those smartphones which run on Android 5 or later Android versions.
Use of this technique
To detect earthquakes, Google’s service uses the ‘accelerometer’ present in Android smartphones, which can work as a mini seismometer.
This is how technology works
The blog explains that when a phone is plugged in and charging, it can detect the onset of an earthquake. If several phones detect earthquake-like tremors at the same time, Google servers can use this information to predict that an earthquake may occur. After this, an alert can be sent to Android smartphones in that area by estimating the epicenter and intensity of the earthquake.
Google says that Internet signals travel at the speed of light. In such a situation, earthquake alerts often reach 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.
What is special is that Google’s earthquake alert system has already been launched in many countries.
