ONC detects M6.1 earthquake near Haida Gwaii

Seismic sensors on Ocean Networks Canada’s seafloor observatory installed offshore Vancouver Island detected an earthquake in the Northeast Pacific Ocean on the morning of 24 April 13:56:16 UTC (7:00 a.m. PDT) 

The magnitude 6.1 earthquake struck offshore the Haida Gwaii Region, with its epicentre about 280 kilometres south west of Prince Rupert, British Columbia.

Haida Gwaii Rumbles Picked Up on ONC's Hydrophone

From Alaska to Vancouver, residents along the west coast felt the powerful magnitude 7.7 earthquake that struck the Haida Gwaii archipelago at 8:04PM PDT, on October 27th, 2012.

ONC seafloor hydrophones also registered the low-frequency rumbles from this earthquake, along with the calls of humpback whales in the area. This recording is from a hydrophone on Barkley Upper Slope, positioned at a depth of 396 m. In this clip, sound has been sped up 250% to make the earthquake noise audible to the human ear. The squeaking noises prior to the main quake are the sped-up whale calls.

With thanks to John...

Haida Gwaii Quake Monitored by NEPTUNE Canada

Just after 8 pm on October 27, a magnitude 7.7 earthquake struck off the coast of BC, at a depth of 17 kilometres and centred 139 km south of Masset in the Haida Gwaii region.

Residents along the west coast—from Alaska to the lower mainland—also felt numerous aftershocks up to magnitude 5.8. No major damage or injuries have been reported.

​

Although similar in size to the earthquakes in Japan (2011) and Chile (2010) this event represents the first regional tsunami tracked by the NEPTUNE observatory.

Haida Gwaii Earthquake and Tsunami

A powerful magnitude 7.7 earthquake struck central Moresby Island in the Haida Gwaii archipelago at 8:04PM PDT, 27 October 2012. Residents along the west coast—from Alaska to Vancouver—also felt several aftershocks up to magnitude 5.8. However, no major damage or injuries were reported. This was the largest temblor to hit Canada since 1949, when an 8.1-magnitude quake hit west of the Queen Charlotte Islands, in the same area.

The following plots show both seismic and bottom pressure data collected by Ocean Networks Canada...
