California Governor Gavin Newsom has been in touch with the White House following last night's magnitude 7.1 earthquake in Southern California. Seismologists said Southern California residents should expect significant aftershocks from Friday's earthquake to continue for about a year.
Officials in Kern County, near the epicenter, said urban search and rescue teams have been deployed. There have been reports of minor injuries, some damage and fires, but no deaths as of yet.
ShakeAlert, a system that warns California residents of nearby earthquakes on their smartphones, failed to send out alerts to Los Angeles residents for this week's two big earthquakes in Southern California.
USGS spokesman Robert Graves said the system is functioning correctly, but the alerts still did not go out. Graves says the magnitude estimate for a follow-up earthquake on ShakeAlert was set too low.
