rattles SLO County and elsewhere in Pacific off Northern California coast.
A 3.3-magnitude earthquake rattled northern San Luis Obispo County Thursday night.
About five hours later, a 3.0 aftershock struck at 3:05 a.m. in nearly the same spot, about 5 miles west of Templeton, followed by a 2.0 aftershock at 9:48 a.m., according to the U.S. Geological Survey.
The first quake, which occurred at 10:22 p.m., was felt as far south as Lompoc and as far north as Bradley, observers reported on the USBS website.
In Atascadero, it felt like a mild vibration that lasted a second or two.
The USGS reported the quake was located at a depth of 3 miles, just north of York Mountain Road and Highway 46 West.
The majority of reports from people who felt the quake came from Atascadero, which had recorded 224 by 10:52 p.m., according to the USGS’ Did You Feel It? website. More than 500 people from around the Central Coast reported feeling the quake.
The quakes were the latest in a recent string of small shakers in the North County.
On April 30, a 3.5-magnitude quake was recorded 16 miles northwest of San Simeon.
And on April 5, a 3.8magnitude quake struck 2.5 miles southeast of Parkfield.
This story was updated with information about the two aftershocks.
