How does the mercalli scale rate earthquakes

WebJul 5, 2024 · There are two commonly-used scales to rate earthquakes 1) the Richter Scale and 2) the Mercalli Scale. The force at which an earthquake shakes the ground is measured with the Richter Scale, which rates the earthquake's actual force on a scale from 0 to 9. A 0 level Richter rating cannot even be felt by a person, while a rating of 8 shakes hard ... WebThe Mercalli Intensity Scale evaluates the intensity of a quake according to observed severity at specific locations. It rates the intensity on a Roman numeral scale that ranges from I to XII. Today, seismologists are using the Moment Magnitude Scale, which measures the size of the earthquake’s fault, and how much of the earth slips at the ...

WebThe Modified Mercalli Intensity Scale By Earthquake Hazards The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to … WebThe Mercalli Scale Another way to measure the strength of an earthquake is to use the observations of the people who experienced the earthquake, and the amount of damage that occurred, to estimate its intensity.

WebThe Mercalli Scale . The Mercalli scale quantifies the power of an earthquake by evaluating its impact on the Earth’s surface. Given human responses and human-made structures, the Mercalli scale rates earthquakes on a scale of 1 to 12, with 1 meaning that nothing was observed and 12 signifying absolute pulverization.
