The magnitude of an earthquake is a number that characterizes the relative size or amount of elastic energy released by such an event (see “Earthquakes, Energy”).It is usually based on measurement of the maximum ground motion recorded by a seismograph (sometimes for a particular wave type and frequency) and corrected for the decay of amplitudes with epicentral distance and source depth due ...

The earthquake struck at a shallow depth of 6.7 miles from the surface, according to the USGS. The intensity of shaking during an earthquake diminishes as the depth increases. That's why the 4.8-magnitude earthquake that hit California at a depth of 19.2 miles Monday had a lower impact.

Mercalli intensity of an earthquake of magnitude 1.0 to 2.0 is recorded if the earthquake was barely noticeable. Intensity count is XII for magnitude 8.0 or more is recorded in case where waves were seen on ground and the damage was high, with objects thrown up in the air.VL #6 - SCIENCEThis video lesson discusses the difference between MAGNITUDE and INTENSITY in a very simple manner and comprehensive explanation.This Video Le...Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake …12.

Magnitude is measured on the ...The intensity and death toll depend on several factors (earthquake depth, epicenter location, and population density, to name a few) and can vary widely. Millions of minor earthquakes occur every year worldwide, equating to hundreds every hour every day. On the other hand, earthquakes of magnitude ≥8.0 occur about once a year, on average. Earthquake magnitude and intensity are both important measurements obtained after an earthquake. They refer to two different aspects of the seismic event, the size and the damage, but they are often confused with one another. The magnitude is a number indicating the size of the seismic event. An earthquake has only one value of magnitude. Such ...MAGNITUDE INTENSITY Earthquake size is a The severity of earthquake quantitative measure of the size shaking is assessed using a of the earthquake at its source. descriptive scale. ...
