A small earthquake which shook the area was centered near Willow Creek this morning.  It joins dozens of others in California this week.  Three of the quakes have happened today.  None of them are large but the amount of quakes seems larger than usual. Cal Ema has noted this on their Twitter account:

Did you know that in the past 7 days there have been about two dozen earthquakes in California? and 3 EQs in last day
