Earthquake Alert (Vibrometer) measures vibrations of the ground using your device’s sensors it's like an earthquake detector, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources.
Records of seismic waves allow you to map the interior of the Earth, and locate and measure the size of these different sources.
Earthquake alarm used Mercalli intensity scale for seismic activities such as earthquakes it's like a vibration meter.
The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake, Earthquake Alert can also be called seismograph or seismometer when used for measuring seismic activity.
To use; place your device on stable surface and turn on the app, It will measure seismic or other vibrations.
The Mercalli intensity scale:
1.0 to 2.0 Felt by very few people; barely noticeable.
2.0 to 3.0 Felt by a few people, especially on upper floors.
3.0 to 4.0 Noticeable indoors, especially on upperfloors, but may not be recognized as an earthquake.
4.0 Felt by many indoors, few outdoors. May feel like heavy truck passing by.
4.0 to 5.0 Felt by almost everyone, some people awakened. Small objects moved. trees and poles may shake.
5.0 to 6.0 Felt by everyone. Difficult to stand. Some heavy furniture moved, some plaster falls. Chimneys may be slightly damaged.
6.0 Slight to moderate damage in well built, ordinary structures. Considerable damage to poorly built structures. Some walls may fall.
6.0 to 7.0 Little damage in specially built structures. Considerable damage to ordinary buildings, severe damage to poorly built structures. Some walls collapse.
7.0 Considerable damage to specially built structures, buildings shifted off foundations. Ground cracked noticeably. Wholesale destruction. Landslides.
7.0 to 8.0 Most masonry and frame structures and their foundations destroyed. Ground badly cracked. Landslides. Wholesale destruction.
8.0 Total damage. Few, if any, structures standing. Bridges destroyed. Wide cracks in ground. Waves seen on ground.
8.0 or greater Total damage. Waves seen on ground. Objects thrown up into air.
