A moderate 4.1 earthquake shakes Southern California.

LA -- A magnitude 4.2 earthquake rocked shelves near the epicenter in a small mountain village east of Los Angeles Friday, but no serious damage or casualties were reported.

U.S. Geological Survey: The 10:55 a.m. quake was centered about a mile (1 kilometer) northwest of Lytle Creek in the San Gabriel Mountains 45 miles (70 kilometers) east of downtown Los Angeles. The depth was 5.5 miles.

A comparable 4.1-magnitude quake rocked Los Angeles less than a week earlier and was felt by Rose Paradegoers in Pasadena on New Year's Day.

In the aftermath of Friday's quake, San Bernardino National Forest Lytle Creek Ranger Station front desk employee Michael Guardado reported the "building shook hard" and "a lot of rocks" fell onto Lytle Creek Road.

In Lytle Creek, Melody's Place bartender Cari Torguson felt “a hard boom and a shake.” She told AP, “It wasn't very long, but it was scary.”

She reported that a decorative glass mushroom over the bar cracked and a jar of instant coffee fell off a shelf in the adjacent business. Not many individuals were inside the building.

Rancho Cucamonga Quakes' minor league baseball stadium was within miles of the quake. “What's in a name, you say,” the squad joked and posted.

The downtown Los Angeles tremor was modest. Shaking was observed in various counties and cities, including Long Beach, some 50 miles southwest of Lytle Creek.

According to senior seismologist Lucy Jones, the quake happened at Cajon Pass, where the San Andreas and San Jacinto faults meet. 

In 1970, a 5.2 earthquake with a 4.0 foreshock occurred nearby, she claimed.
