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.
