Google Unveils Earthquake Warning System Using Android Phones As Seismographs
Michael Simon | PCWorld
First of all, Google is working with California’s ShakeAlert to send a California earthquake alert to an Android phone. SheikhAlert collects signals from a network of hundreds of seismographs across the state, analyzes them at a central site, and sends an alert if an earthquake is detected. According to SheikhAlert, it takes a few seconds to tens of seconds from detecting an earthquake signal to sending a warning. The sooner you receive the warning, the more time you can afford to save lives.
In addition, Google has built the’Android Earthquake Alerts System’ that utilizes the Android phone’s sensor to use the phone as a small seismometer. When a vibration is detected on the phone, it sends a signal to an earthquake detection server, and Google combines the signal with other data to determine whether an actual earthquake has occurred.
The Android earthquake warning system is expected to be able to collect much more localized data through crowdsourcing. Google will first use this information to provide relevant information accurately and quickly when searching for’earthquake’ or’near earthquake’. In the future, it said that it will also be used to inform people in other regions directly. [email protected]
