This morning's tremor follows a cluster of quakes off Vancouver Island last week and a pair of major earthquakes that shook southern California on Thursday and Friday.

Authorities have not issued any tsunami warnings or advisories, and no serious injuries or damage has been reported yet.

The initial temblor was recorded at 2:51 a.m. Friday.

The US Geological Survey's mapping of reports from around the area showed that the quake was felts as far away as Olympia. "We are spooked and still awake", Rob Fuhriman told the station. The agency stated that it was 3.1 kilometers down. The USGS said it received reports of people feeling the shaking from Vancouver to near Wenatchee, Washington. It was the largest in Southern California since the 1994 magnitude 6.6 Northridge natural disaster.

Magnitude 4 earthquakes are felt by humans and may cause damage, according to the Pacific Northwest Seismic Network.

There isn't a connection between this natural disaster and the ones that rocked California earlier this month, Steele said.
