"Epicenter" is a program that automatically calculates the distance to the epicenter of an earthquake in S-P Time (the duration of preliminary tremors).

In the event of a severe earthquake, please evacuate to a safe location rather than utilize this application.

How to use:

1) Please startup the application at the beginning of an earthquake. The measurement will start immediately.
2) When the main shock arrives, please touch the "S Wave Came !" button to complete the calculation.
3) The distance to the epicenter will be calculated at that time and displayed in S-P time.
