The US Geological Survey says the 3.9 magnitude quake struck at 8:24am local time and was centered about five miles east-southeast of Santa Clarita. Shaking was felt across the Santa Clarita Valley, in downtown Los Angeles, and in West Hollywood. There were no immediate reports of damage or injuries. (More earthquake stories.)
