A second earthquake in as many days has been felt by residents on the West Coastof Canada and the U.S.

A 6.2 magnitude quake struck just after 1:30 a.m. PT on Wednesday, more than 264 kilometres off the coast of south-central Oregon, according to the United States Geological Survey (USGS).

Data from the USGS shows residents in Vancouver and on southern Vancouver Island almost 700 kilometres from the epicentre reported feeling the quake, although only mildly.

It was followed two hours later by a 3.5 magnitude aftershock.

Neither event generated a tsunami and officials in Coos Bay, Ore., the nearest community to the quake, said there were no reports of damage or injury.

The quake occurred along the Juan de Fuca tectonic plate, which runs from the west coast of Vancouver Island to northern California. (Earthquakes Canada)

Earlier quake felt in Port Hardy

The quake occurred along the Juan de Fuca tectonic plate, which runs from the west coast of Vancouver Island to northern California. Seismologists say earthquakes along that fault line are frequent as the plate tries to slip below the North American plate.

Wednesday's earthquake and aftershock follows a 4.8 magnitude quake registered off the northwest coast of Vancouver Island at 6:10 a.m.Tuesday.

That quake, whichwas felt by residents located 210 kilometres away in Port Hardy, B.C., alsodid not cause damage or a tsunami, saidNatural Resources Canada.

B.C.-based seismologist Taimi Mulder said the recent activity had no relation to the "Big One," a large-scale earthquake that experts predict could strike the West Coast at some point.
