California's southeastern desert region is still shaking.
Dozens of small earthquakes continue to rattle the Imperial County area near the Salton Sea, following a moderate 3.9 shaker that struck at 8:25 last night. Since Saturday, scientists have recorded at least 175 quakes near the Salton Sea area, including several that were magnitude-3.0 and larger.
Scientists are keeping close watch on the area's increased earthquake activity because it is near a section of the San Andreas Fault that has not ruptured in more than 300 years.
There have been no reports of damage or injury.
