From staff reports

The U.S. Geological Survey recorded three earthquakes above magnitude 6.0 Sunday evening about a 100 miles off the coast of Vancouver Island.

The strongest quake was magnitude-6.8 and occurred at 10:16 p.m.

The Vancouver Sun reported that there was no damage reported and there were no tsunami warnings issued.</s>Three earthquakes measured at magnitudes of anywhere between 6.5 and 6.8 struck off Vancouver Island on Sunday night.

They hit about 200 kilometres west of the island, according to Natural Resources Canada (NRC).

A 6.5-magnitude quake hit at 10:39 p.m., a 6.8-magnitude quake at 11:16 p.m. and another 6.5-magnitude quake at 11:22 p.m., it said.

One of the quakes, which was measured at a magnitude of 6.5, hit approximately 200 kilometres from the Vancouver Island community of Port Alice on Sunday night.

The 6.8-magnitude quake is believed to have struck just under 200 kilometres west of Port Alice.

There were no reports of damage, and “none would be expected,” according to NRC.

The earthquake’s location was pegged at 208 kilometres west-southwest of Port Alice, and 478 kilometres west of Vancouver.

The quake happened at a depth of approximately 10 kilometres and no tsunami was expected.

“We’re still recording very small aftershocks, even this morning right now,” Dr. John Cassidy, a seismologist with NRC told CKNW Monday morning. “But there were three very strong earthquakes last night. They occurred within a span of about 45 minutes.”

There were no reports of the quake having been felt.

Coverage of earthquakes on Globalnews.ca:

Though the quake may seem large compared to other events that have hit the West Coast of North America in recent years, it was far from the biggest.

Earlier this year, a 7.9-magnitude earthquake hit just under 600 kilometres south of Anchorage, triggering a tsunami that was less than a foot high.

Historically, the largest of quakes measuring at a magnitude of five or more near B.C. happened in 1970, when an event hit a magnitude of 7.4, according to Natural Resources Canada.</s>Three earthquakes measured at magnitudes of anywhere between 6.5 and 6.8 struck off Vancouver Island on Sunday night.

The first, a magnitude 6.6, struck at 10:39 p.m. Sunday, 135 miles southwest of Port Hardy, British Columbia. That was followed by the most powerful quake in the string, a magnitude 6.8 at 11:16 p.m. That one was located about 13 miles closer to the island.

Six minutes later, a magnitude 6.5 struck in the same general area as the first two.

A fourth quake, registered at magnitude 4.9, struck at 11:36 in the same vicinity.

There were no immediate reports of damage or tsunami warnings.

There were no immediate reports of casualties or damage from the quakes, the first of which struck just before 11 p.m. PT, around 190 km southwest of Port Hardy, a town on the northeast end of Vancouver Island.

The first quake, reported as magnitude 6.5, was followed by another, of magnitude 6.8, around 40 minutes later.

The third quake was reported at magnitude 6.5 just before midnight, near the same area as the previous two.

CBC meteorologist and seismologist Johanna Wagstaffe said the earthquakes are a reminder that B.C. is in a "complicated" tectonic setting.

"If any one of these quakes had hit closer to land, there would have been devastating consequences," said Wagstaffe.

"Three large ones in a row does seem unusual and I'm sure scientists will be learning as much as they can over the next couple of days about the change in stresses just off our coast."

There were no immediate tsunami warnings following the earthquakes.

Earthquakes Canada also reported a magnitude-4.4 aftershock from the first quake before midnight.</s>The quakes, all measuring more than 6.0 on the richter scale, were about 260 kilometres west of Tofino

Three relatively strong earthquakes, followed by two smaller ones were recorded Sunday night in the Pacific Ocean off Vancouver Island.

The U.S. Geological Survey reported a 6.6 magnitude quake about 260 kilometres west of Tofino, followed by a 6.8 tremor and then a third measuring 6.5. There have been no reports of damage or injurty and a tsunami is not expected.

Survey geophysicist Zachary Reeves said all three quakes occurred in the same general area over the course of about an hour, and at a shallow depth of approximately 10 kilometres. The two other earthquakes that followed were magnitude 4.9 and 4.0.

Reeves, based in Golden, Colorado, described the quakes as “pretty big.”

Emergency Info BC tweeted that the quakes were felt in parts of the province but there were no reports of damage or injury and no tsunami warning was issued.

British Columbia is located on the Pacific Ring of Fire, an active seismic zone where thousands of mostly small earthquakes are recorded annually by sensors in the province.

Most of the quakes happen near the Cascadia subduction zone, an area where the Juan de Fuca and North American tectonic plates converge, stretching from Vancouver Island to northern California.

An earthquake early-warning system recently tested off the B.C. coast could give residents anywhere from 20 seconds to two minutes to prepare before a quake.

The first-of-its kind warning sensors developed by Ocean Networks Canada is installed along the Cascadia subduction zone and when fully operating next March will be able to estimate location and magnitude of a megathrust earthquake.

John Cassidy, earthquake seismologist with Natural Resources Canada, said a tsunami was avoided because the quakes happened along a fault line where sections of the Earth's crust are moving sideways.

"That horizontal type of movement is the least likely to generate a tsunami, because there is no vertical movement of the sea floor. It's a horizontal slipping," Cassidy said in an interview from Victoria.

Several aftershocks were recorded in the hours following the quakes. Cassidy said more were expected.

"The most likely scenario now is that the aftershocks will continue for days or weeks, but they will become smaller as time goes on, and they will become less frequent."

Three earthquakes of that magnitude within a 45-minute window are unusual, Cassidy said, but he added they don't necessarily mean a damaging shaker is imminent.</s>At least two earthquakes of magnitudes 6.7 to 7.0 have struck off the Canadian province of British Columbia this morning.

The first was reported by the United States Geological Survey at around 6.30pm UK time - 10.30pm local time.

There were no immediate reports of casualties or damage from the quake, which hit at a depth of 33 km (21 miles) about 190 km (117 miles) southwest of Port Hardy, a town on the northeast end of Vancouver island.

And there was no immediate tsunami warning.

The larger quake occurred around an hour later about 20km off Vancouver Island and is shallower at around 10km deep.

“These are a very good reminder of plate motions and earthquakes that occur here in this region. We have seen much larger in the past — and we will see larger again in the future — so it really is important to beware of the earthquakes, know what to expect and be prepared.”
