more California news: earthquake number 4 this week

I was about to go to bed 45 minutes ago when I felt the earth move and suddenly thought if it might be another earthquake. And sure enough it was: this is the fourth here in California since Sunday and the second one up here in northern California. The third one occured just earlier today in Southern California--71 miles east of Los Angeles and it registered about 4.9 in magnitude. This latest one, the fourth, is about 6.4 in magnitude and is off the coast of northern California, about 300 miles north west from San Francisco. Things are moving and shaking here in these parts.
