Now with the help of Google, Android provides people with timely, helpful earthquake information when they search, and a few seconds warning to get themselves to safety if needed.
Google said in a blog post thay Firstly, they collaborated with the United States Geological Survey (USGS) and California Governor’s Office of Emergency Services (Cal OES) to send earthquake alerts, powered by ShakeAlert, directly to Android devices in California.
The ShakeAlert system uses signals from more than 700 seismometers installed across the state. A few seconds of warning can allow people to drop, cover, and hold on before the earthquake arrives.
Installing a ground network of seismometers, may not be feasible in all impacted areas around the world. In this senerio Android’s platform can help to detect earthquakes.
Your Android can act as mini seismometer wherever a user is live in the world, joining millions of other Android phones out there to form world’s largest earthquake detection network.
All smartphones with accelerometers that can sense signals that indicate an earthquake might be happening. If the phone detects something, it sends a signal to Google’s earthquake detection server, along with a coarse location of where it occurred. The server then combines information from many other phones to find out if an earthquake is happening.
Google will use earthquake detection technology to share a fast, accurate results of the impacted area on Google Search. When a user search for “earthquake” or “earthquake near me,” he will find relevant results for his area.
