A 4.4 magnitude earthquake struck Southern California around 7:33 p.m. local time Tuesday night, according to the U.S. Geological Survey (USGS). There were no immediate reports of injuries or damage. 

Alaska's North Slope was hit Sunday by the most powerful earthquake ever recorded in the region, the state's seismologist said. At 6:58 a.m. Sunday, the magnitude 6.4 earthquake struck an area 42 miles east of Kavik River Camp and 343 miles northeast of Fairbanks, the state's second-biggest city.

Geologists say they may have found previously unmapped faults in Oklahoma that could be contributing to a sharp increase in induced earthquakes in the state.
