xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx The energy release of an earthquake, which closely correlates to its destructive power, scales with the 3⁄2 power of the shaking amplitude. Thus, a difference in magnitude of 1.0 is equivalent to a factor of 31.6 ( = (101.0)(3 / 2)) in the energy released; a difference in magnitude of 2.0 is equivalent to a factor of 1000 ( = (102.0)(3 / 2) ) in the energy released. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx But in Japan there was a 7.2 quake two days ago, three shocks yesterday & 42 shocks today between 05:46 A.M. & 01:49 P.M. local Munich time, means 02:46 P.M. and 11:46 P.M. in Tokyo.
But news did not talk about yesterdays heavy quake in Yuennan SW China with 25 dead & over 250 injured, but CCTV9 broadcasted the Japan disaster for several hours in their English program. Somebody out there to explain the above calculation in simplified words, please ? #################################################################################################### Am 11.03.2011 um 13:49 schrieb William Gross: > This is a major disaster for Japan, with tsunami affecting the Philippines. > Warnings have gone out to Gaum, Hawaii, Indonesia and the US West Coast. > > Early reports have it as an 8.9, by comparision the Northridge EQ that his > the LA area in 1994 was a 6.7.
