This is a push notification app. which gives you a notice of the earthquake warning with an estimated seismic intensity (the Japanese seven-stage seismic scale) and arrival time of the tremor to the specific location where you registered.

[Initial settings]
Register the current location and the seismic intensity threshold.
The current location is a place where you want to receive the earthquake warning for. The seismic intensity threshold is the standard value. This app. gives you a notice when the estimated seismic intensity is lower than the registered threshold.

[More about this app.]
This app. works with the Earthquake Early Warning (EEW) for advanced users which delivered by the Japan Meteorological Agency (JMA). This means that, when receiving the EEW from the JMA, this application will give you a notice each time. The EEW for the advanced users has a characteristic which derivers warning several times for each earthquake with improving the precision of a seismic intensity. So, this app. may give you several notices with different estimated seismic intensity and arrival time.
Also, with this app. you can view the information of all earthquakes occurred in the past.
