App that turns smartphones into quake detectors

New York, May 22: Researchers on Sunday released a Japanese version of an Android app that takes information from smartphones to detect earthquakes and eventually warn users of impending jolts from nearby quakes.

Developed by a team from University of California, Berkeley (UC Berkeley), the app called MyShake is available through the Google Play Store which can be accessed via the MyShake website.

It runs in the background and draws little power, so that a phone’s onboard accelerometers can record local shaking any time of the day or night.

For now, the app only collects information from the accelerometers, alyses it and, if it fits the vibratiol profile of a quake, relays it and the phone’s GPS coordites to the Berkeley Seismological Laboratory in California for alysis.

Since it was first released in English on February 12, more than 170,000 people have downloaded the app from around the world, and on any given day 11,000 phones provide data to the system.

“We think MyShake can make earthquake early warning faster and more accurate in areas that have a traditiol seismic network, such as Japan, and can provide life-saving early warning in countries that have no seismic network,” said Richard Allen, director of the Berkeley Seismological Laboratory and professor and chair of UC Berkeley’s department of earth and planetary sciences.

Since February, the network has recorded earthquakes in Chile, Argenti, Mexico, Morocco, Nepal, New Zeland, Taiwan, Japan and across North America, including induced earthquakes in Oklahoma.

The system has recorded earthquakes as small as magnitude 2.5 and as large as the April 16, 2016, magnitude 7.8 earthquake in Ecuador.

Once enough people are using the app and the bugs are worked out, UC Berkeley seismologists plan to use the data to warn people miles from ground zero that shaking is rumbling their way.

“In my opinion, this is cutting-edge research that will transform seismology,” said UC Berkeley graduate student Qingkai Kong, who developed the algorithm at the heart of the app. (ians)
