Vibration Meter - Seismometer

The quake meter is an app which uses the seismograph or seismometer in your phone to measure the strength of vibrations, tremors, earthquakes, and even the vibrations of the human body or any other objects around you. Using the accelerometer in your phone, our app allows you to detect and record seismic waves generated by earthquakes, volcanic eruptions, avalanches and any other sources of seismic activity.

Once the activity is measured, the graph feature presents a record of the ground motion at the point of measurement. Any ground movement or object is presented as a function of time along three Cartesian axes, with the z- axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface.

During a span of measurement, you will track average and max values and see current corresponding Mercalli scale descriptions. You can set up your app to display current acceleration, XYZ or Mercalli scale values on the main screen.

Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage:
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.

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