“Devastating megathrust earthquake” a “substantial hazard” for Haida Gwaii, Canada-US study warns

A “devastating megathrust earthquake” could hit Haida Gwaii sometime in the future, according to Canadian and US studies carried out after the magnitude 7.8 earthquake off Haida Gwaii on Oct. 27, 2012 and the 7.5 magnitude quake off Craig, Alaska, a few weeks later on Jan. 5, 2013. The 2004 Indian Ocean earthquake and the 2011 Tōhoku earthquake in Japan, both accompanied by major tsunamis are recent examples of “great” (higher than magnitude 8.0) megathrust earthquakes. Most of the concern on the west coast has…

Fault zone map Douglas Chanel

New Douglas Channel geological studies near completion

Three studies of the geology of Douglas Channel are near completion and publication, according to Natural Resources Canada. That news comes as studies, released today, warn of a major megathrust earthquake on the fault west of Haida Gwaii. Northwest Coast Energy News asked the Geological Survey of Canada if there were any recent updates available after the agency said that a survey had located a “possible fault” on Hawkesbury Island during studies for the Enbridge Northern Gateway Joint Review Panel. “Devastating megathrust earthquake” a “substantial…

Is Kitimat ready for a “big one?”

Studies of the October 2012 magnitude 7.8 Haida Gwaii earthquake show that the region is vulnerable to a “major megathrust” earthquake along a newly confirmed fault line west of the islands. That earthquake was felt in Kitimat and Kitamaat Village and a tsunami warning was issued within a few minutes. So have the District of Kitimat, the Haisla Nation Council or Rio Tinto Alcan changed or upgrading their earthquake and tsunami plans in the past couple of years? “Devastating megathrust earthquake” a “substantial hazard” for…

Commentary: The earthshaking difference between Enbridge and LNG

Buried deep in the LNG Canada environmental assessment application, a reader will find a key difference in attitude with at least one of the group of companies planning liquified natural gas development in the northwest and Enbridge Northern Gateway. It’s an earthshaking difference, since it’s all about earthquakes. The documents filed by LNG Canada with the BC Environmental Assessment Office and the Canadian Environmental Assessment Agency acknowledge that there is a possibility of an earthquake (a one in 2,475 year event) at the LNG terminal…

NOAA west coast tsunami warning text messages fail to deliver any info–at least on an Android

For the past month, text message tsunami warnings from the West Coast and Alaska Tsunami Warning  Center  have transformed from clear, concise vital information to incomprehensible computer code with a link to a useless URL–at least on my Bell Android Samsung phone. Take the warning for this morning’s 4.7 magnitude earthquake which shook southern California.  The Los Angeles Times is now reporting there have been more than 100 aftershocks from the quake. My phone beeped this morning with the tone that let me know that this…

Harper government stalling on earthquake readiness for Haida Gwaii, Cullen says

The Harper government is stalling on requests for better earthquake preparation on Haida Gwaii, according to the NDP MP for Skeena Bulkley Valley, Nathan Cullen. Speaking to northwest reporters on Thursday, February 28, Cullen who is NDP House Leader, said: “The government has been stalling since November when we’ve been asking them to meet the communities and meet their demands for funding, because as we see more earthquakes come, the support hasn’t been there from the federal government.” The Skeena Bulkley Valley riding includes Haida Gwaii which…

The tsunami, Twitter and the Zones: Did social media amplify government generated confusion?

Kitimat, BC and New York City had one thing in common this week, the misuse and use of social media, Twitter and Facebook, that spread both accurate warnings and dangerous misinformation about an impending disaster. In the case of New York and the surrounding area, it was Superstorm Sandy that caused widespread devastation. For Kitimat it was the tsunami warning after the 7.7 earthquake off Haida Gwaii and no damage but a lot of worry for residents. New York has a population of millions, it…
