Just a few days after a 4.4 magnitude earthquake hit the San Jose area, a second cluster of quakes has rattled the South Bay, the United States Geological Survey reported this morning.

Things began at 4:13 a.m., the USGS says, with a 3.0 magnitude earthquake with an epicenter about 4.5 miles from the South Bay city of Gilroy. It had a depth of about 3.1 miles.

The second earthquake struck about 20 minutes later, at 4:32. It clocked in at a 2.6 magnitude, the USGS says, with a depth of 3.16 miles and a different epicenter than the first, with this one located 5.5 miles from Gilroy.

No damage was reported in the quakes, the second this week following Monday's San Jose temblor. Unlike that quake, which was felt as far north as San Francisco, the shaking was barely felt outside the area, with most respondent reporting "weak" shaking on the USGS's Did You Feel It? map as of publication time.
