Considering the trend line . . . say an average of those recent quakes in this map here:

http://earthquake.usgs.gov/earthquakes/recenteqsus/Maps/US10/27.37.-120.-110.php

Would the fault likely cause a progression of quakes along that current line to curve South of Bakersfield or what . . .

ASSUMING say the line was extended 2-3 times it’s current length.

Pure speculation, I understand.

depends on the movement in those areas. i live near that line so I have been paying more attention to it. If you notice around Angeles National Forest there has been very little movement so i expect something to move around that area. but I don’t expect it to be huge.

Two things that I have been trying to research and understand of late are “Seismic Shadow” and “Stress Transfer”.

The Mexico Quake, caused rather unusual waveforms for a quake of only 7.2 and even more interesting was the waveforms from yesterday afternoon's 5.3!

In my layman's description of the Shadow, imagine a car windshield and a rock hits it at speed. Where the stone hit there will be a large hole or pit, that is the quake’s epicenter. Now as you drive further, you start to notice hairline cracks appearing, that is your aftershocks.

The consequence of each hairline crack is that it lessens the rigidity of the windshield which promotes the hardened glass to be seen more as what it is and that is liquid.

Under these conditions, the windshield will not shatter.

That is the seismic shadow.

I will post later on the stress transfer side of this.
