Pop quiz: San Simeon or Irish Hills?


Some interesting studies today. 

Above are two hypocenter cross sections (within the circles) crossing the upthrust zones of the area of the San Simeon M6 earthquake of 2003 (close to NS section) and the other crossing the Irish Hills (SW-NE section) at the site of the Diablo Canyon plant, the latter with no recent M6 earthquakes. But maybe one on the way?

The San Simeon cross section is for the period 1988 through 2002, before the 2003 earthquake occurred. If you can identify which of the above is San Simeon do you see portents of a coming earthquake?  All earthquakes in the Hardebeck catalog  from 1988
