Portola Valley, Woodside hit by series of small quakes

By the Daily Post staff

A series of small earthquakes occurred in Portola Valley and Woodside within 24 hours of one another, according to the U.S. Geological Survey.

None of the dozen or so earthquakes that occurred were over a 2.9 magnitude. Generally, earthquakes under a 3 are not felt by many people, with the USGS saying earthquakes at a 1 intensity are only felt “under especially favorable circumstances.” The majority of the earthquakes were under 2.5 intensity.

Only one was hit in Woodside, with the epicenter occurring at the 300 block of Ridgeway Road at 11:10 Thursday night.

The rest all happened less than a mile away from one another in Portola Valley, one set of small earthquakes, with the largest being a 2.6 magnitude, happened between 10:02 and 11:26 p.m. Thursday and 4:55 and 6:52 p.m. yesterday. Most occurred either in the Windy Hill Preserve or along Portola Road between Westridge and Brookside drives.
