The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other. chit chats prohibited items

"WebMagnitude measurement requires instrumental monitoring for its calculation, however, assigning an intensity requires a sample of the felt responses of the population. This is then graded according to the EMS intensity scale. For example, Intensity 1, Not felt, 2, Scarcely perceptible, 3, weak, felt by a few, up to 12 assigned for total devastation.

The Modified Mercalli Intensity Scale … WebFeb 15, 2024 · The intensity, or macroseismic intensity, represents a classification of the severity of ground-motion shaking during an earthquake on the basis of observed effects at a given place (Grünthal et al. 1998 ). The word “macroseismic” refers to perceptible effects of earthquakes as opposed to instrumental observations.

WebWhile an earthquake has just one magnitude, its levels of intensity decrease with distance from the epicenter. The waves get smaller as they travel away from the fault. Think of a lightbulb: It has one wattage, but the brightness that energy produces decreases with distance as the light spreads out. Intensity also can vary depending on geology. WebB. Earthquake intensity is based on ground motion recorded by a seismograph; magnitude is based on the amount of damage produced. C. Contour lines representing Richter values are used to delimit zones of earthquake intensity; the greater the quake, the higher the intensity values and the wider the zones.
