There was a 5.6 magnitude earthquake just north of San Jose a few minutes ago. We didn’t feel much at our house in Oakland, though the water in a water cooler sloshed softly back and forth for nearly twenty seconds. My wife’s sister in Modesto said it shook their whole house and that it was the strongest earthquake she has ever felt. She hasn’t yet gotten hold of her daughter in Santa Cruz. The epicenter would be roughly in the center of a triangle formed by Oakland, Modesto, and Santa Cruz.
