PHOENIX (3TV/CBS 5) - An earthquake shook Southern California and people in Arizona could felt it too.
It happened just before 8:30 p.m. on Friday.
The earthquake's epicenter was about 11 miles from Thursday's 6.4-magnitude earthquake in Ridgecrest, California, according to the United States Geological Survey.
The earthquake was originally reported as a 7.1 magnitude earthquake and then reportedly downgraded to 6.9. However, scientists with the USGS later said it was 7.1.
Officials in San Bernardino County reported homes shifting, foundation cracking and retaining walls coming down. At least one person suffered minor injuries and was being treated by firefighters, they said.
Gas leaks caused structure fires throughout Ridgecrest, residents reported water main breaks, and the power and communications were out in some areas, Mark Ghilarducci, Director of California Governors' Office of Emergency Management, said.
The earthquake also rattled our Los Angeles affiliates KCAL and KCBS' studios while they were on the air for their 8 p.m. newscast.

According to Dr. Lucy Jones, a seismologist, Thursday's quake was a foreshock. She said Friday's earthquake was on the same fault.
Scientists said Friday's earthquake was 10 times stronger than Thursday's.
The quake was felt downtown as a rolling motion that seemed to last at least a half-minute. It was felt as far away as Mexico and Las Vegas.
If the preliminary magnitude is correct, it would be the largest Southern California quake in 20 years.
People from all over the state of Arizona said they could feel it, from Lake Havasu City to Chandler to Congress to Sun City.
