REDLANDS–An active earthquake “swarm” that began February 13th is keeping elements of the Inland Empire on edge.

The shaking have been traced with an epicenter south of Redlands in San Timoteo Canyon.

Triple back-to-back quakes felt right before noon Friday were among the strongest at M3.6.

Seismologist Tom Heaton at Cal Tech described the sequence as ‘not unusual’.

“It’s really difficult to predict what may happen with a swarm. Sometimes they continue for weeks or months. Sometimes they’re over in several days.”

Earthquake ‘swarms’ usually occur in active geothermal areas. This sequence is connected with the San Jacinto Fault it is happening at a depth of 3 to 4 miles.

There has been no reported damage.
