USGS said the quake struck at around 6.39 p.m. three miles north-northeast of Santa Rosa at a depth of 3.48 miles (5.6 kilometers).
The quake caused some damage, with Santa Rosa Fire Department responding to calls for assistance with people stuck in elevators and reporting gas leaks.Southern Californian Seismologist Lucy Jones, Ph.D., said there was a five percent chance the quake would be followed by a larger quake in the next three days.
A magnitude 4.4 quake would be the strongest in three years in the Bay Area, according to meteorologist Drew Tuma, who took to Twitter after feeling it.
“Would expect a lot of people in the North Bay to have felt a strong jolt,” he wrote on Twitter.
USGS indicated the quake occurred along the Rogers Creek fault, which is a potentially right-lateral strike-slip fault. The last time a moderate-sized quake, which is between 5.6 and 5.7 on the Richter scale, happened on this fault near Santa Rosa in October 1969.
