aftershocks along fault too long for M5.6 |
The California map, zoomed in (see link), has the tiny aftershocks over what looks to be 40 km along a NW-SE trend (along the San Jacinto fault or whatever the local strand is called there). That is way too long for a M5.6....I would expect a M5.6 rupture to be a couple of km across........so what is happening? is the whole 40 km piece creeping...triggered slip? And, what does this mean for a M6.8 or 7 rupturing through that whole illuminated part of the fault? I'm guessing that the distribution of aftershocks is not a function of mislocation because they define such a narrow lineament..... Also: of that 40 km piece were to fail, would that advance the time of a future rupture on the San Andreas fault to the north...is that the San Bernadino segment?
