The magnitude of an earthquake is measured by a machine called a seismometer. A seismometer produces a seismograph. According to the Earthquake Glossary, a seismograph is defined as “an instrument used to detect and record earthquakes. Generally, it consists of a mass attached to a fixed base.
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified ...
Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre. We can, therefore talk about a magnitude 5.4 ML event with intensity of 6 EMS in the epicentral ...The earthquake events are measured either according to the magnitude or intensity of the shock. The magnitude scale is known as the Richter scale. The magnitude relates to the energy released during the quake. The magnitude is expressed in absolute numbers ranging between 0 and 10. The intensity scale is named after Mercalli, an Italian ...quake size. When an earthquake is recorded on the standard instrument, the greatest excursion of the wiggly trace is measured and compared with that of a reference magnitude 3.0 earthquake at the same epicenter-to-station distance.

Intensity III means no damage, and not everybody feels it. Intensity VII or VIII involves moderate damage, particularly to poorly constructed buildings, while Intensity IX or X causes considerable damage. Richter magnitude scale. Developed in 1935 by Charles Richter, this scale uses a seismometer to measure the magnitude of the largest jolt of energy released by an earthquake. Moment magnitude scale. Measures the total energy released by an earthquake. Moment magnitude is calculated from the area of the fault that is ruptured and the distance ...The energy released in an earthquake is a static number, regardless of how close you are to the epicenter. In contrast, the impact of the earthquake, in terms of shaking and damage caused, depends greatly on how close you are to the epicenter. The shaking and damage caused by an earthquake is termed the intensity, which is measured ...May 12, 2023 · In the United States, the Modified Mercalli (MM) Intensity Scale is used to determine the magnitude of earthquakes.
