WebA magnitude 9.0 earthquake, which rarely occurs, releases over a million times as much energy as a magnitude 5.0 earthquake. Ranking Earthquake Intensity. Earthquake intensity is very different from earthquake magnitude. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Whereas the magnitude of an earthquake is one value that describes the size, there are many intensity values for each earthquake that are distributed across the geographic area around the earthquake epicenter. The intensity is the measure of shaking at each location, and this varies from place to … See more The time, location, and magnitude of an earthquake can be determined from the data recorded by seismometer.

What is a seismic zone, or seismic hazard zone? - USGS

WebNo, earthquakes of magnitude 10 or larger cannot happen. 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. 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. highways or dieways
