A small and slightly jolting earthquake struck north of Morgan Hill this morning, making its presence felt as far north as Napa.

The magnitude 4.3 earthquake occurred at approximately 10:40 a.m. The U.S. Geological Survey pinpointed the location 11 miles north of Morgan Hill, seven miles east of Seven Trees and 16 miles east-southeast of San Jose's City Hall.

There were no immediate reports of earthquake damage, but some trains were experiencing 7-10 minute delays while inspectors checked for damage.

The earthquake's rattle was felt throughout the Bay Area and beyond from Santa Rosa and Napa on the north, Soledad on the south, and Groveland in Tuolmne County on the east.

It was described by a few residents as "a couple of sharp shakes" that could be felt along the city's "Miracle Mile."
