Is today's earthquake an aftershock, or the unzipping of a known 'marcher' fault? Obviously, that's a stupid rhetorical question! At least the quakes will be farther away, and our friend's house wouldn't be bothered. However, once these 'little' quakes have lined all their ducks in a row, I'm still expecting an overlapping M8, which is sufficient to 'finish' that end of the fault for another 200 years. M6's and 7's just ain't gonna do it!
