Earthquake mercalli scale.

Mercalli intensity scale. The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. Unlike with the Richter scale, the Mercalli scale does not take into account energy of an earthquake directly. Rather, they classify earthquakes by the effects they have (and the ... Apr 15, 2022 · What is earthquake Mercalli? The Mercalli Scale is based on observable earthquake damage. From a scientific standpoint, the magnitude scale is based on seismic records while the Mercalli is based on observable data which can be subjective. Thus, the magnitude scale is considered scientifically more objective and therefore more accurate. The great earthquake broke loose some 20 to 25 seconds later, with an epicenter near San Francisco. Violent shocks punctuated the strong shaking which lasted some 45 to 60 seconds. The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada.

Earthquake shaking is measured using the Modified Mercalli Intensity (MMI) Scale. Whereas the magnitude of an earthquake describes how much energy is released by an earthquake, calculated according to the length of a fault rupture and how far it slipped, the MMI scale describes the intensity of earthquake shaking at a specific location by considering its effects on people, objects and buildings. Richter Scale vs. Mercalli Scale •Richter Scale -Also know as the moment of magnitude scale -Mathematical equation that measures the amplitude of the seismic waves recorded on a seismographs -Magnitude is expressed as whole numbers and decimals -A number 3 on the scale is 10 time more powerful than a number 2 earthquakeThe Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.

Mercalli scale: [noun] a scale of earthquake intensity ranging from I for an earthquake detected only by seismographs to XII for one causing total destruction of all buildings. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale.
