A new smartphone app has been designed to give out early warning of earthquakes and it could be ready by the first quarter of 2014.
The smartphone app is capable of alerting the user between a time-frame of few seconds to one minute, before a tremor strikes. Scientists at the World Science forum in Rio de Janeiro explained that the app will send out alerts to an individual on the basis of his location in relation to the epicentre.
This app is based on the technology used by an early warning system prepared by a team under the Director of the UC Berkeley Seismological Laboratory, Professor Richard Allen, News24 reported.
The app captures the initial energy originating from the tremor, the so-called <span data-scayt_word="" p"="" data-scaytid="14">“P</span> wave” or primary wave, which rarely itself causes damage but acts as a pre-cursor to the intensity of the quake on a Richter scale. </p> <p> According to the report, the technology uses algorithms to detect when a quake is starting and determine its strength and location and when it is likely to reach its zenith and also issues alert to the residents in potentially affected areas. </p> <p> The algorithms will use data from regional networks monitoring seismic networks, the report further added.</p> <p> However, those located at the actual epicentre of the quake will not receive the early warning on their cell phones. </p> <p> This <span data-scayt_word="app" data-scaytid="16">app</span> uses a combination of various <span class="scayt-ignore" data-scayt_word="smartphone" data-scaytid="17">smartphone</span> functions, such as accelerometers and gyroscopes, to determine movement, as well as <span data-scayt_word="GPS" data-scaytid="20">GPS</span> and <span data-scayt_word="Wi-Fi" data-scaytid="21">Wi-Fi</span> localization functions as a magnetometer to indicate direction. </p><p></p><p></p><p></p>
