USGS Reports Series of Small Earthquakes in San Jose

A series of small earthquakes struck San Jose late Tuesday, according to the USGS.

The first temblor with a magnitude-2.7 was reported at 8:23 p.m. in the East Foothills and Alum Rock area. The quake was immediately followed by a pair of temblors (M2.6 and M2.5) in the same area, according to the USGS.

Then at 8:51 p.m., a magnitude-3.2 earthquake shook the area, according to the USGS.

The NBC Bay Area quake map showed at least 10 small quakes struck the area in within 50 minutes after the initial quake was reported at 8:23 p.m.

USGS spokesperson Leslie Gordon said Tuesday night's quake swarm was not significant enough to indicate anything out of the ordinary.

The Alum Rock area has had earthquakes in the past and any temblor less than a magnitude-4.0 is normal for the area, Gordon said.

The North Bay was also active late Tuesday with a swarm of quakes reported a few miles north of Santa Rosa. In all, there have been 48 small quakes in the past 24 hours.
