To start, we’ll use this technology to share a fast, accurate view of the impacted area on Google Search. And lucky for us, the speed of light is much faster! We’re essentially racing the speed of light (which is roughly the speed at which signals from a phone travel) against the speed of an earthquake. The server then combines information from many phones to figure out if an earthquake is 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 means your Android phone can be a mini seismometer, joining millions of other Android phones out there to form the world’s largest earthquake detection network.Īll smartphones come with tiny accelerometers that can sense signals that indicate an earthquake might be happening. Starting today, your Android phone can be part of the Android Earthquake Alerts System, wherever you live in the world. So we’re using the reach of Android’s platform to help detect earthquakes. Installing a ground network of seismometers, as California has done, may not be feasible in all impacted areas around the world. Building the world’s largest earthquake detection network
