Intensity 10


Intensity 10 : A measure of the effects of an earthquake at a particular place at the Earth's surface on humans and (or) structures. The intensity at a point depends not only upon the strength of the earthquake (magnitude) but also upon the distance from the earthquake to the epicenter, the depth of the hypocenter and the local geology at that point. Several scales exist, most of them giving the intensity in 12 degrees, usually written as Roman numerals. Most frequently used are at present the European Macroseismic Scale (EMS-98), and in the United States the Modified Mercalli scale and the Rossi-Forel scale. There are many different intensity values for one earthquake, depending on how far you are away from the epicenter; this is unlike the magnitude value, which is one number for each earthquake as a measure of the amount of seismic wave energy released by it
