A suprising warning has been issued by officials that there is an increased possibility of a moderate to strong earthquake striking southern California within the next few days.
A "Swarm" of smaller tremors set off the alert, due to the worry that these may have increased the pressure along the San Andres fault line.
Only two of the tremors were above 4.0 on the richter scale but the area that they hit are of particular concern of seismologists.
“This is close enough to be in that worry zone,” said seismologist Lucy Jones to Los Angeles Times. “It’s a part of California that the seismologists all watch.”
