MONTEREY COUNTY (CBS SF) -- An earthquake with a magnitude of 4.2 hit in the area of Aromas in Monterey County just after 8 p.m. Saturday night, according to the USGS.
The temblor was reported with an initial magnitude of 4.5 by the United States Geological Survey, but was later adjusted to 4.2. The quake happened at about 8:01 p.m. and was centered about 2.5 miles southeast of the census designated area of Aromas and north of Salinas.
At least 5 aftershocks rattled through the area following the initial shallow quake, the largest measuring 3.0 at 8:06 p.m. The epicenter was near the famed San Andreas Fault.
Aromas Fire District Capt. Steven Baumeister -- whose station is located about five miles west of the epicenter -- said his team was returning to the station from an incident at the time of the quake.
"Everything was in order. We did a quick check around the area and there are no reports of damage or injuries," said Baumeister. "We received a few calls, but that's it."
In the San Francisco Bay Area, BART trains ran at reduced speeds while officials made sure there was no damage to tracks.
Callers flooded the Santa Clara Police Department's 911 phone line asking about the quake.
"As a reminder, 9-1-1 is NOT an information line. Please do not call 9-1-1 to ask, "Was that an earthquake?" the police sent out in an alert.
