A 3.4 magnitude earthquake shook San Jose at 12:02 p.m. Monday, the U.S. Geological Survey reported.
The epicenter was 7 miles east of Milpitas and 9 miles northeast of San Jose City Hall, and 5.3 miles below ground.
The jolt, felt as far away as Soquel and Pleasanton, was the latest in a series of small tremors triggered by the restless Calaveras Fault, which routinely releases stress caused by the earth's shifting continental plates.
No damage or injuries were reported.
According to the USGS, the last significant earthquake on the northern end of the central segment of the Calaveras Fault was a 5.4-magnitude Alum Rock shaker in October 2007.
