"MyShake" application that uses smartphones as a global earthquake detection and notification network

In order to minimize the damage of the earthquake, early detection and caution are important. Applications that detect such earthquakes now using smartphones that exist in every part of society and immediately notify the occurrence of earthquakes in the future "MyShakeOperation of the system has been started.

MyShake is a project that the University of California Berkeley can do. By using the built-in acceleration sensor on the smartphone, it is possible to detect the occurrence of an earthquake instantly, from now on, based on the data uploaded to the server, it detects the occurrence of the earthquake and is in the vicinity We are aiming to have a function to notify people's apps of earthquake occurrence.


MyShake is an application released for Android and will be developed for iOS in the future. This time I installed it on the Nexus 6P of the editorial department. On an Android deviceGoogle PlayAccess and tap "Install".


When installation is completed, tap "Open" to start the application.


This is the screen after launching the application. Four menu items of "RECENT (recent)" "SAFETY (safety)" "SENSOR (sensor)" "PAST (past)" are displayed at the top,RECENTEarthquakes with magnitude 2.5 or more that occurred in the last 7 days are displayed.


When scrolling the screen and displaying near Japan, it looks like this


Tapping the icon showed that an earthquake of magnitude 5.7 occurred near the Izu Islands.


"SAFETY" is written in English, how to prepare for an earthquake and how to deal with it when it occurs.


On the screen of "SENSOR", the movement sensed by the acceleration sensor installed in the terminal is displayed in real time. The movement of the three axes of the X axis (blue), the Y axis (red), and the Z axis (green) is reproduced in the graph.


The three waves displayed to the left of the graph are those recorded when the terminal is moved up and down, right and left, and back and forth respectively. You can understand it when you actually move it, but how the graph responds to just a few movements is well transmitted.


A large earthquake of the past is displayed in "PAST". As you can see on this screen, the American West Coast is an earthquake-prone zone, so you can sense the background behind the development of this MyShake application.


It's like being in Japan. of courseTohoku Region Pacific Coast EarthquakeAlthough it was displayed, somehow caused the Great Hanshin-Awaji earthquakeHyogo ken Nanbu EarthquakeAnd, a memorable new Taiwan earthquake was not displayed.


This application has been developed with a focus on continuing to operate basically in the background, and therefore it is said that ingenuity such as minimizing the consumption of the battery is being done. In addition to being useful for earthquake research, it seems that it will be able to obtain important information in the future, so it may be useful to install it somewhat.
