Two back-to-back earthquakes, including a magnitude-4.2, shook Southern California Saturday evening, according to the USGS.
The magnitude-4.2 quake struck at 7:18 p.m.about 8 miles north of Castaic, about 20 minutes after a magnitude-3.0 temblor struck the same area.
"All of the sudden it was two big rattles and little rumbles afterwards," Castaic resident Jessica Shickle said. "It was like the Lord literally just took our house and just kind of gave it a couple shakes, and that was it and it went away."

"You're always bracing yourself hoping it's not the big earthquake," she said.
The USGS first reported the later quake as a magnitude-4.5 but downgraded it to a magnitude-4.2.
Residents reported feeling shaking from the second quake in downtown Los Angeles, Hollywood, Silver Lake, Koreatown, Valencia, Thousand Oaks, Chatsworth, Sylmar, Studio City, Pasadena, Pico Rivera Bakersfield, Long Beach and West Hollywood.
"This really is a very small earthquake," USGS seismologist Dr. Lucy Jones said. "It's a size that's relatively common in Southern California. I did a check and there were eight earthquakes 4.2 and larger in 2014," Jones said.
The Did You Feel It? page on the USGS website had more than 1,300 responses as of 8 p.m.
No damage was reported but some residents said they watched chandeliers rattle and felt their building shake.
