    A 3.3 magnitude earthquake struck near Alamo Monday morning, one day after a series of small quakes rattled near neighboring Danville, according to the USGS.

    Monday morning's temblor rattled at 4:55 a.m. approximately 2 miles east-northeast of Alamo, 3 miles northwest of Diablo and 4 miles southeast of Walnut Creek, according to the USGS.

    "It was a pretty severe tremor," Alamo resident Carolyn Carter said. "The house really shook; I could hear the light fixtures and china moving around in the cupboard."

    UC Berkeley Seismologist Angela Chung got a heads up seconds before the Monday morning temblor. Chung is part of a team of scientists working to perfect an early warning system.

    The team is working to make such a system available to everyone before the Big One hits. Chung says seconds can make a huge difference.

    "It doesn’t seem like a lot of time, but that’s enough time for you to get under the table, drop, cover, hold on and get to a safe place," she said.

    At least eight earthquakes ranging in magnitude from 1.5 to 3.0 rocked an area roughly 1 mile away from both Danville and Diablo and 4 miles southeast of Alamo between 10:34 a.m. and 3:25 p.m. Sunday.
