[QUOTE="dru, post: 1652173, member: 3047"] sorry, the little mathematical/anal part of my brain feels the need to clarify a few things about earthquake strength. They are based on base 10 logs, but the richter numbers correspond to the amplitude of the earthquake "waves" So a 5.0 has an amplitude of 10x that of a 4.0 However, because of the way that amplitudes correspond to energy contained, a 5.0 will possess about 31.6x more energy than a 4.0 Also, and this is an interesting tidbit I picked up from wikipedia, but if you look at the richter numbers of earthquakes, and their relative frequency, there appears to be a log10 relationship in earthquake occurence. i.e. an earthquake of 4.x occurs about 10 times as often as an earthquake of 5.x Okay, everyone please continue on [/QUOTE]
