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...

Cascadia Subduction Zone

A subduction zone (Bebout et al., 1996) is an area where two plates are converging, with one plate moving beneath the other. As the down-going (subducting) plate moves deeper, it transports water into depth where it is heated and released. The heat from the mantle and core causes the surrounding rocks to melt and become fresh magma for volcanic eruptions. The down-going plate is recycled in the Earth’s mantle. At the Cascadia subduction zone the ocean crust of the Juan de Fuca plate is subducting beneath the continental crust of the North American plate. At subduction zones, there usually is an area where the two plates become locked. This means that they are not slipping past each other and frictional stress can build up, storing large amounts of energy. When this stress finally...

Tale of Two Tsunamis

 

A magnitude 8.8 earthquake struck Chile in February 2010, generating a tsunami that crossed the Pacific, with measurable waves recorded throughout coastal British Columbia.

A recent paper, published in Pure and Applied Geophysics, describes this tsunami in detail and compares it to the Great Chilean earthquake and tsunami of May 1960.

Tilting at Boreholes

The W.M. Keck Foundation has awarded $1 Million to Woods Hole Oceanographic Institution (WHOI) for a new geodesy observatory to be connected to Ocean Networks Canada and the Ocean Observatories Initiative Regional Scale Nodes (OOI RSN). This interdisciplinary project, led by Dr.Jeff McGuire and John Collins of WHOI, will allow scientists to monitor three Cascadia subduction zone segments off the coasts of Vancouver Island, Washington and Oregon. Along this subduction zone, the Juan de Fuca plate...

Samoan Tsunami Detected

When a devastating magnitude 8.0 earthquake occurred roughly 200 km south of the Samoan Islands at 17:48:11 UTC on Tuesday September 29, 2009, it generated a trans-oceanic tsunami that spread at jet-like speeds throughout the Pacific Ocean.

At 04:57:33 UTC on 30 September, roughly 11 hours after the earthquake, five of our newly deployed Bottom Pressure Recorders (BPRs) and one...
