A second earthquake shook southern California on Friday night, topping the powerful quake that hit the region just a day earlier, authorities said.
The latest temblor was given a preliminary magnitude of between 6.9 and 7.1, officials said.
It struck near the Mojave Desert town of Ridgecrest at about 8:20 p.m. and lasted for about a minute, the US Geological Survey said.
