Some residents of the South Okanagan region of B.C. were awakened by a small earthquake early Friday morning, but there are no reports of any damage.
The 4.3-magnitude quake was felt in Penticton, Rock Creek, Kelowna, Grand Forks and other south-central B.C. communities, according to the Earthquake Canada website.
The quake hit at 5:09 a.m. PT about five kilometres underground roughly 85 kilometres south of the Canada-U.S. border near the town of Riverside, Wash., according to Jessica Turner, a geophysicist with the U.S. Geological Survey in Colorado.
The USGS initially rated the quake as a magnitude 4.3 as well, but later upgraded it to a magnitude 4.6.
"On our website people have reported it being felt in the Washington area and also up in the Canadian side," Turner said.
"There have been reports in the cities of Penticton and Kelowna they have felt this earthquake that occurred today."
When compared with the West Coast, the Okanagan Valley is not nearly as seismically active.
The last notable earthquake in the region was a 4.4 in 2005, but a 6.4-magnitude earthquake 300 kilometres off the west coast of Vancouver Island in September was felt by people in highrises in Kelowna.
