Earthquake

reference-wikipedia The following table lists the approximate energy equivalents in terms of TNT explosive force – though note that the earthquake energy is released underground rather than overground. [ 19 ] Most energy from an earthquake is not transmitted to and through the surface; instead, it dissipates into the crust and other subsurface structures. In contrast, a small atomic bomb blast (see nuclear weapon yield ) will not, it will simply cause light shaking of indoor items, since its energy is released above ground. 31.6227 to the power of 0 equals 1, 31.6227 to the power of 1 equals 31.6227 and 31.6227 to the power of 2 equals 1000. Therefore, an 8.0 on the Richter scale releases 31.6227 times more energy than a 7.0 and a 9.0 on the Richter scale releases 1000 times more energy than a 7.0. Thus, Approximate Magnitude Approximate TNT for Seismic Energy Yield Joule equivalent Example -0.2 7.5 g 31.5 kJ Energy released by lighting 30 typical mat...
