There were no reports of damage or injuries after five earthquakes struck within seven hours off the northwest end of Vancouver Island on Monday.

The tremors began as minor quakes, but grew stronger as the morning turned toafternoon.

Earthquakes Canada said the tremors measuredatmagnitude:

  • 5.1 (8:44 a.m. PT).
  • 5.6 (11:13 a.m.).
  • 5.8 (11:49 a.m.).
  • 6.0(12:56 p.m.).
  • 4.8 (3:38 p.m.).

Allfive originated in the Pacific Ocean, more than 100 kilometres off Port Hardy, B.C., at a depth of about five kilometres.

Earthquakes Canada said there were no tsunami warnings, no reports of damage or injuries, and none would be expected from quakes that size.

Another smaller quake, estimated at magnitude 4.3, was also detected Monday at 9:32 p.m., about 29 kilometres west of the village of Queen Charlotte and hundreds of kilometres to the northwest of the earlier tremors.

Area ishot spot for quakes, seismologist says

Andrew Schaeffer, a seismologist with Earthquakes Canada,says they had received no reports of anyonefeeling the quakes.

"You'd have to be ready and waiting, and expecting to feel it. It would be pretty hard to distinguish it from a big truck driving by a few hundred metres away."

Theseare not the kind of earthquakes that produce tsunamis, he added.

Speaking after the first four quakes had been reported, Schaeffer saidthe area in the Pacific off Vancouver Island is a hot spot for seismic activity, with magnitude 5 quakes recorded several times a year.

"Having four in a row is a little more than what we would usually have anticipated but certainly not out of the norm for this active region," he said.

In the last year, there havebeen more than 100 earthquakes between magnitude 3 to 5, he said.

"It's also not that uncommon to have a series of earthquakes in close proximity to each other in time," he said.

He saidMonday's quakes happened inthe Winona Basin, a northern piece of the Juan de Fuca plate that broke off at some point.
