Early Detection of Earthquakes

Early detection is important in earthquake-prone areas, seismic equipment for this are but expensive. A group of researchers and a lab of Deutsche Telekom have now presented an Android app, which detects earthquakes in a timely and cost effective.

Before an earthquake, seconds can decide about life and death. Early warning systems are therefore particularly important. Not all countries in

earthquake-prone areas but have the seismic equipment to warn in a timely manner. A group of researchers from the University of Berkeley is committed to the task, to find a solution for this problem.

Researchers use the accelerometers in smartphones to detect early seismic activity before the actual quake. They have placed different Android phones for a year on a vibrating table and collected data from the built-in sensors. Now they have released the Android app MyShake.

Decentralized seismograph

The result should be a decentralised seismograph composed thousands raw data about seismic activity with the help of neural networks in real time to the overall picture. Compared to a fixed system of standard scale-out Smartphone ideally can set up a network a considerably dense sensor network. Paper author and seismologist of the University of Berkeley Richard Allen said that the group be could hersagen earthquake with 93 percent success rate.

The Android app MyShake collects such data and forwards to the survey U.S. Geological. To do this, the Smartphone must be however quietly on a flat surface. In addition, researchers need data of at least 300 smartphones in a 12,000 Qdaratkilometer comprehensive region to make reliable predictions. The app is available free on the Google play store for Android version 4.1 download.

[Update 15.2.2015 11:12]:

Deutsche Telekom meanwhile said, Telekom innovation laboratories were involved in Silicon Valley to develop of the app. The objective is to create a worldwide seismic sensor network and impending quakes to warn end users. Deutsche Telekom wants to present the app on the Mobile World Congres in Barcelona. (akr)
