Surveys mark the center of the quake 11 kilometers north of Cabazon and say it began at 4:49 am. The second was a 3.2-magnitude three minutes later in the same area, according to the U.S.
There were no immediate reports of damages or injuries, but residents of San Diego County and Tijuana reported being jolted awake. The epicenter was located almost 7 miles north of Cabazon, a town of about 2,500 located 90 miles east of downtown Los Angeles.
At least two earthquakes-one of them capable of causing moderate damage-rocked an area of Riverside County near Banning today and was felt in Los Angeles about 90 miles from the epicenter.
Earthquake Track, a seismological database reports estimates there are 10,000 to 15,000 earthquakes worldwide between 4.0-4.9 magnitude each year.
Veteran seismologist Lucy Jones tweeted that the quake occurred near a complex part of the San Andreas fault that can not be clearly seen on the surface there because it is covered by another fault. Local resident Brianna Orrantia said she also heard it before she felt it, just minutes after waking up.
Others thought the earth tremors must have been closer to their location based on their strength. Many thought the temblor must have been closer to their location based on its strength, like a woman in Pico Rivera, in southeast Los Angeles County, who tweeted with surprise that, "Wow the quake was all the way in Banning, I thought it was here".
