Two light earthquakes within less than 90 minutes of each other struck off Port Alice on northern Vancouver Island Monday afternoon.
The first was a 4.6-magnitude quake that came at 1:27 p.m., about 170 kilometres west of Port Alice. Only one report of shaking was received within the first few hours of that quake, said Natural Resources Canada seismologist John Cassidy. “There was a report from Victoria of ‘heard rumbling and felt light shaking.’ ”
The second was a 5.4-magnitude earthquake that came at 2:44 p.m., about 190 kilometres west of Port Alice.
The earthquakes were in an area where they tend to be shallow, in about the 10-kilometre range, Cassidy said.
“It’s one of the most seismically active regions in Canada, that area just offshore of Vancouver Island.”
He said there was a 5.1-magnitude earthquake in the same general area Feb. 1.
There was no tsunami danger from Monday’s events, Cassidy said.
He said that anyone wanting to let scientists know about impact from an earthquake can do so by going online to: earthquakes canada.nrcan.gc.ca/index-en.php and filling out the questionnaire on the “Did you feel it” link.
