Swarm of small earthquakes near Redlands
REDLANDS–An active earthquake “swarm” that began February 13th is keeping elements of the Inland Empire on edge.
The shaking has been traced to an epicenter south of Redlands in San Timoteo Canyon.
Triple back-to-back quakes felt just before noon Friday were among the strongest at M3.6.
Seismologist Tom Heaton at Cal Tech described the sequence as ‘not unusual’.
Earthquake ‘swarms’ usually occur in active geothermal areas. This sequence is associated with the San Jacinto Fault it is happening in a depth of 3 to 4 miles.
There has been no reported damage.
