DEVORE (CBS) — Many Inland Empire residents were shaken out of bed Saturday morning by a magnitude 3.8 earthquake that struck near Devore and sent several aftershocks rumbling through Southern California.

The temblor hit at approximately 8:07 a.m. with the epicenter 2 miles northwest of Devore, according to Lucy Jones, of the U.S. Geological Survey. She clarified that the quake did not occur along the San Andreas fault.

The USGS originally reported the earthquake at a magnitude 4.1 but later downsized that estimate to a magnitude 3.8.

No injuries or damages have been reported.

“It felt like someone was doing jumping jacks upstairs,” said Hesperia resident Tim Sutorus. “I felt the ground start to undulate up and down.”

Sutorus said he felt the shaking for about 7-9 seconds. While his daughter felt the rocking motion out in Rancho Cucamonga, he said his wife was in the garage and didn’t feel the earthquake.

Devore resident Noretta Barker said all the shaking woke her up and, even, made her back crack.

The quake was felt as far away as downtown Los Angeles, approximately 60 miles from the epicenter.

The USGS reported that a 2.0 aftershock hit about a half mile away two minutes after the temblor. Inland Empire residents say they’ve felt at least three aftershocks.

You won’t expect to see any sort of significant damage, said John Bellini, of the USGS.

“This 4.1 earthquake happens a few times a year in Southern California so it’s not an unexpected thing…very rarely do you see a 4.1 earthquake [occur] before a larger event,” said Bellini, addressing concerns that this earthquake may trigger a larger one.

Geological experts have been forecasting that a very large earthquake, dubbed the “Big One”, is long overdue for Southern California.

The quake was also blamed initially on the San Andreas fault, but Jones said the quake was more likely a result of seismic activity along the Cucamonga fault.
