Strong earthquake tremors were felt in Kolkata and surrounding areas this morning. Since then there is an atmosphere of fear among the people there. At many places, buildings kept shaking for a few seconds and people came out of their homes in fear. The epicenter of the earthquake was near Tungi area of ​​Bangladesh, from where strong tremors were felt at around 10:38 am.
After the tremors, a question was arising again and again in the minds of people. Did you receive an earthquake alert on your phone? Actually, nowadays smartphones send earthquake warnings in time, but only when this feature is on in the phone.
How do smartphones give earthquake warning?
Small motion sensors present in smartphones can sense even slight vibrations. When multiple phones nearby simultaneously record strong vibrations, this data is immediately transmitted to a central server. The server considers it as an earthquake and immediately sends an alert to the nearby users. It only takes a few seconds for this alert to arrive, but even those seconds can give someone a chance to reach a safe place.
