Mercalliintenzitásskálával

The Mercalli Intensity Scale, often referred to as the Mercalli Scale, is a seismic intensity scale used to measure the intensity of earthquakes. It was developed by Italian physicist Giuseppe Mercalli in 1902 and revised in 1903 and 1931. The scale is based on the effects of shaking on the surface and on the response of man-made structures and natural features.

The scale ranges from I to XII, with each number representing a different level of intensity. The lower numbers (I to V) describe slight to moderate shaking, while the higher numbers (VI to XII) describe severe shaking and structural damage. The scale is qualitative, meaning it describes the effects of the earthquake rather than its physical properties.

The Mercalli Scale is used to assess the impact of earthquakes on human activities and the environment. It is particularly useful for comparing the intensity of different earthquakes and for understanding the potential for damage in a given area. However, it should be noted that the scale does not provide a direct measure of the earthquake's magnitude or energy.

The Mercalli Scale is still used today, although it has been largely superseded by the Modified Mercalli Intensity (MMI) scale, which is based on the same principles but includes more detailed descriptions of the effects of shaking. The scale is named after its creator, Giuseppe Mercalli, an Italian physicist who made significant contributions to the study of earthquakes and seismology.
