Vibration Meter, seismograph for Android

11 things about Vibration Meter, seismograph

1. In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale.

2. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location.

3. Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you.

4. Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks.

5. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface.

6. Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake.

7. Richter Scale assigns a magnitude number to quantify the energy released by an earthquake.

8. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake.

9. Graph presents a record of the ground motion at a measuring point.

10. It measures the effects of an earthquake and it is distinct from the moment of magnitude.

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