A pair of earthquakes about 230 miles (370 kilometers) apart struck Southern California overnight, just two days after a moderate Northern California quake.
Meanwhile, neighboring Reno, Nevada, continues to tremble.
A 4.4-magnitude quake early today was centered 12 miles (19 kilometers) from the resort town of Lake Isabella, which is about 50 miles east of Bakersfield in the southern part of the state.
There were no immediate reports of injuries or damage.
Stephanie Canning said she was the only one in the Lake Isabella bar where she works who felt the quake. "I was sitting there and I saw the karaoke box shake, and I felt the ground move about three times,'' Canning said.
The quake hit barely four hours after a 4.2-magnitude temblor outside of Palm Springs, roughly 230 miles away.
Lake Isabella is about 300 miles south of Reno, Nevada, which has experienced a flurry of moderate temblors in recent weeks.
Farther north, near the quake-prone coastal town of Eureka, California, a magnitude-5.4 event — the largest out West in the past week — shook the region Tuesday. That temblor was centered about 250 miles northwest of Reno.
