A magnitude-6.4 earthquake struck British Columbia,last friday the U.S. Geological Survey said.
The quake struck 12:41 p.m. PDT (1941 GMT) at a depth of 14.3 miles (23 kilometers) about 173 miles (279 kilometers) west of Vancouver, the USGS said. The quake was initially reported to have a magnitude of 6.7 but was later downgraded by the USGS.
The quake's epicenter just off the west coast of Vancouver Island, south of Port Hardy.
According to Stephen Halchuck, a seismologist with Natural Resources Canada, said that the quake lasted for 20-30 seconds and rattled buildings across Vancouver Island and the southwest portion of British Columbia. He said there has been no immediate reports of damage in the region.
According to the West Coast and Alaska Tsunami Warning Center no tsunami was expected.
"This event was not the type to generate a tsunami. It's size was not large enough and the mechanism of the earthquake would not have generated a significant tsunami," said Halchuck.
However, the West Coast and Alaska Tsunami Warning Center advised that underwater landslides may cause "local tsunamis" at some coastal locations that experienced strong tremors.
Many in the small coastal community of Zeballos, is at sea level, felt the earth move under them.
As a precaution, the Washington state Transportation Department sent inspectors to check for damage at the Alaskan Way Viaduct, an aging elevated highway on the Seattle waterfront, as well as two other bridges.
