Do you know most newer mobile phones can detect earthquakes and how powerful it is? And using smart mobiles you can save your life from earthquake warnings.
Let me tell you how?
Your mobile can work as basic seismometers, the same instrument that is used to measure the magnitude of earthquakes and volcanoes. You don’t need to install any apps, just the built-in web browser would suffice.
Open this page in Google Chrome or the Safari browser on your mobile phone. You should see a continuously moving waveform but if you slightly turn over or shake your mobile device, the graph will capture seismic activity in real-time much like a seismograph.
The seismic intensity will depending upon how vigorously (or slowly) you are shaking the phone and will also change based on the orientation of the device.
Most newer mobile devices have built-in accelerometers and gyroscopes and as you move the physical hardware, the changes in the orientation of the device and acceleration are detected by the browser which are then mapped into the seismograph.
Update: However most of the scientist also working on Mobile’s GPS system to detect earlier warnings of earthquakes but it’s still in process. In US “the United States Geological Survey (USGS)” along with a coalition of university partners are developing and testing an earthquake early warning system called “ShakeAlert” for the west coast of the United States.
