 * That's how earthquakes work. Usually there are aftershocks to deal with. At least it wasn't NEARLY as strong as the first one, a little over a tenth of the energy --128.205.229.150 (talk) 20:51, 20 January 2010 (UTC)
 * ...6.1 is a tenth of 7.0? – Juliancolton  &#124; Talk 21:30, 20 January 2010 (UTC)
 * IIRC, on the Richter scale each number magnitude is 30 times stronger than the one before it; i.e. a magnitude 7 is 30x the power of a magnitude 6. Not sure if that applies here, or are they using the moment magnitude scale? Tempodivalse [talk]  21:39, 20 January 2010 (UTC)


 * I thought it was a logarithmic scale, so every 1 higher is 10x stronger. I'm wrong, though, looking it up each 1.0 higher is 31.6x the energy. So even better then --128.205.229.150 (talk) 22:16, 20 January 2010 (UTC)


 * The scale quantifies amplitude, not energy. Amplitude and energy are related, but are not the same thing. 94.193.134.98 (talk) 12:47, 21 January 2010 (UTC)
