4.7 magnitude earthquake shakes Central California — including SLO County

»» Story update: Another earthquake, this one magnitude 3.4, reported near Hollister

A 4.7-magnitude earthquake in Tres Pinos rocked parts of California on Tuesday, with some of the shaking felt as far away as San Luis Obispo County.

According to the U.S. Geological Survey, a quake hit just outside of Tres Pinos, located in San Benito County just south of Hollister and 20 miles east of Salinas, around 12:30 p.m.

The quake was originally reported as having a magnitude of 5, then 4.8, but has since been downgraded, according to USGS.

A 2.6-magnitude aftershock was reported in Tres Pinos soon after, followed by 1.9-magnitude and 1.7-magnitude quakes in nearby Pinnacles.

Residents in San Luis Obispo County, notably in Paso Robles and Atascadero, reported feeling light shaking, according to the USGS website. The quake was felt as far north as Napa.

The latest quake comes a day after two earthquakes rattled the San Francisco Bay area, scaring some with a large sonic “boom.”

Seismologist Lucy Jones, founder of the Dr. Lucy Jones Center for Science and Society, tweeted on Tuesday that the quake near Hollister was “too far from yesterday’s (Bay Area quakes) to be connected.”

Two other smaller quakes were reported in San Luis Obispo County on Tuesday, according to USGS. A 2.2-magnitude temblor hit northeast of Cambria around 5:30 a.m. and a 1.7-magnitude quake happened northeast of Cayucos around 12:30 a.m.

The quakes struck just days before the 30th anniversary of the Loma Prieta earthquake, which hit during the 1989 World Series. That quake heavily damaged Santa Cruz County and parts of the Bay Area.
