Vibration Meter is a free app that can measure the vibration (seismograph, body tremor, seismometer). This app uses phone sensors to measure vibration or the earthquake, and it shows a reference as a seismic detector. Using this app, you can check vibrations both on the Richter scale and on the modified Mercalli intensity scale. To calibrate application click on the button - Calibrate, put your device on the flat surface and wait till value stabilize. It should take about 20 seconds. After that click OK button and enjoy the earthquake! App shows reference to earthquake vibrations as classified by internationally used Mercalli intensity scale for seismic activities such as earthquakes. The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake. Vibration Meter can also be called seismograph or seismometer when used for measuring seismic activity. Mercalli intensity scale: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. Some countries use Richter scale instead of Mercalli scale. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.
