WebEarthquake Effects Estimated Number Each Year; 2.5 or less: Usually not felt, but can be recorded by seismograph. Millions: 2.5 to 5.4: Often felt, but only causes minor damage. 500,000: 5.5 to 6.0: Slight damage to buildings and other structures. 350: 6.1 to 6.9: May cause a lot of damage in very populated areas. 100: 7.0 to 7.9: Major ... An earthquake radiates energy in the form of different kinds of seismic waves, whose characteristics reflect the nature of both the rupture and the earth's crust the waves travel through. Determination of an earthquake's magnitude generally involves identifying specific kinds of these waves on a seismogram, and then measuring one or more characteristics of a wave, such as its timing, orientatio…

WebThe effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction. WebA magnitude 7.0 releases about 32 × 32 = 1024 times as much energy as a magnitude 5.0 earthquake. A 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.
