Someone on CNN said yesterday that during a normal quake sequence, you can expect the strongest aftershock to have an intensity rating of about 1 Richter Scale lower than the main quake. I wonder if that also applies to "Great Quakes" of 8.0 and above? The reason being that if the main quake registers 8.8 as this one did, then an aftershock of 7.5 to 7.8 would be a helluva quake in itself! This quake was located along the fault offshore. If an aftershock of about 7.5 would strike closer to the coast and population centers, then its conceivable that the aftershock could kill and do more damage in Chile than the main quake itself! Just a thought. However, I am a little skeptical that a 1 Richter Scale lower type of aftershock would apply to a great quake like this. Could be wrong, but my hunch is that the enormity of the energy released by the earth in the main quake won't come near to being duplicated in one single aftershock, but instead we'll continue to see a large number of aftershocks rolling in at about the 6.0 to 6.3 level.
