A series of earthquakes, at least 10, rattled Monterey and San Benito counties Friday morning when the San Andreas Fault’s tectonic plates released small tremors of energy.

The cluster of earthquakes struck between 5:58 and 6:22 a.m., the largest of which measured 4.1 magnitude, according to the U.S. Geological Survey.

The first quake was the largest, a magnitude 4.1 temblor, recorded at 5:58 a.m. and centered about 7.5 miles south of Tres Pinos and 18 miles east of Salinas, according to the USGS.

The second, a magnitude 3.2 quake, was recorded at 6:01 a.m. and centered about 6.8 miles south of Tres Pinos and 18 miles east of Salinas.

On the USGS website, more than 529 people reported feeling the largest quake, including as far away as San Jose.
