Earthquake tracking system from Google!
Google revealed on Tuesday a series of updates to Android phones including earthquake detection capabilities.
The Android Earthquake warnings system operates anywhere around the globe and makes a mini seismometer for every Android device. Google claims this is the world's biggest network of Earthquake detection.
Marc Stogaitis, the Principal Software Engineer at Google wrote about this in a blog article:
“All smartphones come with tiny accelerometers that can sense signals that indicate an earthquake might be happening. If the phone detects something that it thinks may be an earthquake, it sends a signal to our earthquake detection server, along with a coarse location of where the shaking occurred,”
This crowd-sourced earthquake tracking system allows Google's alerts and resources to be more accurate if you search for "earthquake near me" after you feel trembling. The update on Tuesday also provides earthquake warnings to Android devices in California through partnership with the U.S. Geological Survey and the Emergency Management Office of the Governor of California. The system uses pulses including over 700 seismometers around the states to alert you to find cover even before it starts moving.
Google stated that over the next year it is working to carry the earthquake warnings to other states beyond California. The warnings came just one day after a 4.6 magnitude earthquake occurred in Southern California. There are around 20,000 earthquakes in the U.S. every year, according to the National Earthquake Information Centre.
Technology such as Google's can help with early detection of these quakes, but there is also more sophisticated machine-learning technology that can predict big tremors by processing seismic signals to identify fault lines.
