Measure phone's vibration and the earthquake with your phone.

Vibration Meter is in the 4th set of Smart Tools collection.

This app uses acceleration sensor to measure vibration or an earthquake, and it shows a reference as a seismic detector (seismograph).

The measured values are related to Modified Mercalli Intensity scale (MMI). If it is inaccurate, you can calibrate it so that maximum value is about 10-11.

Please use the result only for reference because Android devices have a wide variety of performance and sensitivity.
