SANTA ROSA, Calif. (KGO) -- A preliminary 4.4 magnitude earthquake struck near Santa Rosa Tuesday night, according to the United States Geological Survey.

The quake struck about 2.4 miles north-northeast of Santa Rosa around 6:39 p.m., according to the USGS, and 7.8 miles southeast of Windsor in Sonoma County. USGS seismologist Austin Elliott. says a 3.9 magnitude aftershock after the initial quake less than a minute later.

Elliott says the quake occurred on the Rodgers Creek Fault, which is part of the San Andreas Fault system.

The Santa Rosa Fire Department tweeted that crews are responding to reports of "odors of gas, gas leaks, fire alarms as well as stuck elevators."

They say there are no reports of injuries at this time.
