5.6 earthquake in N. California; strongest since Loma Prieta

Pretty big quake in Mt. View/peninsula; biggest I've ever been in, though only 6 years in California. No reports of injuries so far, anecdotal reports of minor damage.

Report on KTVU says 5.6, the biggest since Loma Prieta. Epicenter NE of San Jose, 7 miles east of Milpitas. I think must be on the Calavaras.  Wikipedia says there has not been a major quake on the Calavaras in recorded history; it is not a locked fault, meaning it slides along pretty freely, and so major earthquakes are unlikely. TeeVee confirms it was on the Calavaras. Also says minor damage. Two light poles down in San Mateo. Dams and reservoirs in the area seem unharmed. Levees will be checked tomorrow. 15 aftershocks so far (11pm).

There are liteally dozens of earthquakes in the Bay Area every week, 98% are not even perceived by the public.  They are published on Fridays in the Chrony. This was not one of those. While not a killer (as far as we know) this one tonight was a real shocker for many.
USGS MAP of epicenter HERE.

Tracings (and my observations) show the quake lasted for several minutes, though the big swingers stopped after about 15-20 seconds. Was perceived most strongly in the South Bay and especially east of the epicenter.
What's happening around the bay area????
