Earthquakes Canada says there have been no reports of damage, and “none would be expected”.
The magnitude-4.4 quake hit in foothills northwest of San Bernardino about 5:38 p.m.at a depth of about three miles, a report from the U.S. Geological Survey said.
Residents on Vancouver Island and on the Lower Mainland were awoken late Tuesday night as a 4.3 magnitude quake rocked the region.
John Cassidy, a seismologist with Natural Resources Canada, said those numbers are subject to change slightly, but one thing is certain: the quake was felt on the South Coast more than any other since 2001.
The sources say the quake occurred about 19 km NNE of Victoria.
There were no immediate reports of damages or injuries, however.
SkyTrain’s Expo and Millennium lines were shut down for approximately an hour as a safety precaution to ensure the elevated guideways were not damaged by the tremors.
The aftershocks registered 3.8, 2.7 and 3.2 southwest of Devore, according to the USGS.
Police departments across Metro Vancouver and southern Vancouver Island reported floods of calls, but no significant requests for assistance.
BC Hydro said it had not detected any quake damage and there were no disruptions to transmission and distribution systems.
The quake followed another several hours earlier near San Bernardino, Calif., that measured 4.4.
One of the largest earthquakes more than a decade shook Victoria, B.C. and portions of Western Washington.
