Publisher Description

In Japan, earthquakes occurs hundreds of times every day, including what human does not feel.

So people are using this app in preparing against earthquakes.

You can see a real time image of a ground motion of Japan.

This app will notify you of earthquakes by alarm sound, voice or/and vibrator before the ground motion arrives a place you are.

All people who travel to Japan need this app.


(1) Real time image

You can see a real time image of the ground motion of Japan. Also you can see real time waveform of the ground motion up to 16 observation points.

(2) Notification of the earthquakes

A notification server is always monitoring the ground motion of Japan even if you don't use this app. When the earthquake occurs, the server sends notifications to your device by using Google Cloud Messaging before the ground motion arrive place you are.

The notification condition can be set by an estimated seismic intensity and a region. You can choose a combination of alarm sound, voice, vibrator, auto-popup of the app and message as a notification method. The alarm sound can be changed to what you like. The voice notification speaks the seismic intensity and regions.

Earthquake Early Warnings (EEW) are issued by the Japan Meteorological Agency (JMA) are also displayed and spoken in English.

This app also supports automatic tweets of the earthquake information and images of the ground motion and waveform plots.

A waveform display function is valid when connecting to New server and operating in a landscape mode.

To change server: Menu > Server/Run mode > Server selection

To add new point, touch a Japanese map and select observation points.

To change display order of waveform plots, drag each waveform to desired place.

To delete a waveform plot, touch the waveform longer than 0.5 second.


This app uses data of "Realtime ground-motion monitoring system (Kyoshin monitor)". It is a web service which is provided by National Research Institute for Earth Science and Disaster Prevention (NIED).

I deeply appreciate them who are providing such a valuable data.
