Mobile App: Utilitzation of 'Mobile Phone Seismometers'

Jomst C.

Mobile phone seismometers has been developed by researchers to an app that makes smartphones detect earthquake and are delighted of the patronage and usage of their citizen network in science

Launched for Android this February, the App MyShake has been downloaded a couple hundred thousand times since then.

Smartphones that have downloaded and used the app have measured and listed hundreds of quakes worldwide, even small tremors of magnitude 2.5.

A complex systematic algorithm gives life to the MyShake app that analyzes various data of vibrations recorded by the smart phone's accelerometer.

The set of equations has been made to identify or "trained" to differentiate motion of users and other motions that may resemble an earthquake.

Such as apps for fitness and health, MyShake runs on the phone's background to monitor the user's activity.

When the app gets a reading, it sends data to its server. The server or central then measures and locates the size and location of the earthquake.

A Professor from the University of California at Berkeley named Professor Richard Allen, indicated that the app became a useful tool for users to know what is happening in their area or city.

The professor was recently speaking at the Fall Meeting of the American Geophysical Union (AGU) and announced that a new version of MyShake, now pushes notifications to the person using it. This update is essential, eventually, it will be used to issue alerts from the readings from the devices.

In a massive number of users, the devices nearest to the center of the quakes would detect the shaking and then forward the warning to all users in the area and further about the danger going the user's way.

Though the warning may only be a few seconds, it will be more than enough to inform and warn people to be able to take cover and do the necessary cautionary steps.

The app is not close to that ideal scenario yet, and current reading that the app issues are served from the usual seismic network, and usually arrives after a few minutes after the occurrence. But as more users join the system of the MyShake, and the developers continue on improving and developing the system, the ideal scenario of having a network-based early warning system for earthquakes will be made possible.
