California community hit by dozens of earthquakes

NY Times- The ground has been restless in this California community 35 miles east of San Francisco. Since late last year, dozens of earthquakes have rumbled through San Ramon and its tidy neighborhoods and cul-de-sacs, disrupting the suburban calm.

They have been mostly quick, and relatively weak, rumbles occurring here and there, with a few hefty thumps in between. Until this week, they were all a magnitude of 4 or below — not powerful enough to cause any real damage, but frequent enough to make even longtime residents of this earthquake-prone region puzzle over what’s going on.

Monday brought the biggest jolt yet, and the most active day since the quakes began in November, when an earthquake with a 4.2 magnitude rattled nerves and windows. It was felt as far away as San Francisco.

“Everyone is really on edge here,” said Seema Sophia Aggarwal, who has lived in San Ramon for two and a half years. “The ground was bouncing and jerking from morning until night.”
