Pleasanton means mid Calaveras fault, which could trigger more motion on the hayward fault.
It was Pleasant HILL, not PleasantON. Off by about 20 miles. And it might have been “only” a 4.5, but it hit about a mile from us, and our place shook pretty good.
Knocked my router off the shelf, but no real damage.
I hear we are getting a bunch of 1-2 aftershocks, but not feeling them.
Calaveras blame the frogs
Maybe PG&E can do a wide-area “PSGS” (Public Safety Gas Shutoff)!! Might save a lot of lives in a quake! ;-) (/sarc)
Oops, make that “Pleasant Hill”, not Pleasanton as “ssaftler” pointed out. Didn’t feel it in FR HQ area.
