Vibrate & Seismic Meter

Vibrations & Seismic Meter measures vibrations using your device’s sensors on all 3 axes: X, Y, Z and 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.

Vibrations are shown in all 3 directions: X, Y, Z in different colors and specific directions can be turned off or on for more accurate directional readings.

To use; place your device on stable surface and measure seismic or other vibrations.

Mercalli intensity scale

I. Instrumental - Not felt. Recorded by seismographs.

II. Weak - Rarely felt, usually only on top floors of high buildings.

III. Slight - Felt indoors, like a passing light truck.

IV. Moderate - Windows, dishes, doors rattle. Like passing train.

V. Rather Strong - Felt by all. Small objects upset.

VI. Strong - Books off shelves. Trees shake. Isolated damage.

VII. Very Strong - Difficult to stand. Many poor buildings damaged.

VIII. Destructive - Significant damage. Branches broken from trees.

IX. Violent - General panic. Serious damage. Ground cracking.

X. Intense - Most buildings destroyed. Rails bent slightly.

XI. Extreme - Rails bent greatly. Pipelines destroyed.

XII. Catastrophic - Near total damage. Objects thrown into the air.
