A series of earthquakes rattled the Pacific Ocean off northern Vancouver Island Sunday night and early Monday morning, although officials reported no damage or tsunami threat.

Three notable earthquakes were detected in less than seven hours, with magnitudes ranging from 4.9 to 5.4.

The first, measuring magnitude 4.9, was recorded shortly before 8 p.m. Sunday about 170 kilometres offshore from Port Hardy.

Less than two hours later, a stronger magnitude 5.4 earthquake was detected west-southwest of Port Hardy.

It was the largest of the three events.

A third earthquake, initially reported at magnitude 5.2, was recorded shortly after 2 a.m. Monday in the same general offshore region.

All three occurred well out in the Pacific Ocean, between roughly 166 and 210 kilometres from Port Hardy.

No one reported feeling the shaking, and there were no reports of damage.

Emergency officials said none of the earthquakes posed a tsunami threat to British Columbia.

Earthquakes Canada’s latest catalogue lists the two largest events at magnitude 5.4 and 5.1, along with several smaller earthquakes in the same area during the sequence.

Preliminary earthquake measurements can be revised as additional data is analyzed.

Earthquake activity is common off British Columbia’s coast, but the weekend’s events were among the largest recorded in the region during the past month.

Residents are reminded that earthquakes can happen without warning.

During significant shaking, people should drop to the ground, take cover beneath a sturdy desk or table when possible, and hold on until the shaking stops.
