Vancouver is a possible massive earthquake target, but only few care about it!

Vancouver

With its location in the Cascadia subduction zone, a seismically-active area, the question is not if an earthquake will hit the Canadian city, but when.

For generations Vancouverites have heard that a major earthquake is due to hit the city “once every 500 years”, but it has never happened. As a result, locals have grown pessimistic and even indifferent to the possibility of it ever happening. The last major quake was thought to have hit the city about 300 years ago, long before western settlers arrived.

Yet, with its location on the Pacific west coast, along a stretch that includes Anchorage, Seattle, San Francisco and Los Angeles, cities that have all been hit and damaged by earthquakes, new research points out Vancouver’s time could be closer than originally thought.

According to research released by the University of Oregon earlier this year, there is a one-in-three chance that a major earthquake could strike the Pacific Northwest, an area home to Seattle, Portland, Vancouver and Victoria, within the next 50 years.

The researchers believe Cascadia is not one large subduction zone stretching from northern California to British Columbia, as previously thought, but at least four separate segments. They suggest that instead of the entire fault rupturing at once, it will break into smaller parts with more frequent earthquakes.

“We need to be ready for it,” states Vancouver Mayor Gregor Robertson, who has made environmental issues for the city his top priority since taking office two years ago.”There’s a huge role for citizens to be prepared. I don’t think Vancouverites are anywhere near as ready as they should be in their homes. We see significantly more energy and preparedness and awareness around California, for example. We’re looking at some of their educations efforts to implement here.”

Heavy aftershock rattles Chile main earthquake area

This report will receive regular updates.

UPDATE 14:42 UTC ( local 10:42)
The Chile Emergency services reported that the earthquake has been experienced by the local people as follows :
Hioghest values came in from Bio-Bio province
Concepción, Talcahuano, Laraquete  and Arauco, Mercalli V = Moderate shaking
Quinchamalí and Cobquecura,  Mercalli IV = light shaking

2010 Chile earthquake

February 27 damage picture - Image via Wikipedia

Earthquake Report comment :
Major aftershock  in the coastal waters near Conception.
All values are preliminary. Details will follow.
A strong shaking will have been perceived in the coastal towns (Mercalli VI) – Population  which will experience this shaking : 75,000.
GDACS just issued an GREEN earthquake report (look link below).
Following the GDACS statistics, approx. 1 million people live in a radius of 50 km around the epicenter.
The earthquake (aftershock) occurred in the middle of the night (3:28).
This is one of the heaviest aftershocks in Chile since many weeks.
Based on our experience with Chilean earthquakes of the recent months, eventual damage or injuries will be limited (although we have to mention that every earthquake has its own specifics) .
So far (50 minutes after the earthquake), no reports in the local press (of course it is in the middle of the Chilean night).
As we have not received incoming alarms on our QuakeSOS app so far, we presume that the human perceived impact is limited to very limited (we know although that Chilean people are not easily frightened anymore, as aftershocks make a part of Chile daily life since February 27).
Almost all Chile emotions are going these days to the 33 miners who are stuck 700 meters under the surface in the San José mine in Copiapo and have to stay there for at least a couple of months more. Everything else is getting in Chile today less attention.

Most important Earthquake Data:
Thursday, September 09, 2010 at 03:28:02 AM at epicenter
Depth (Hypocenter) : 17 km
Geo-location(s) :
34 km (21 miles) SW (236°) from Concepcion, Chile
70 km (45 miles) NNE of Lebu, Bio-Bio, Chile

This earthquake list covers minor and major earthquakes in the world.
If a more detailed page is present, the earthquake line will be linked to the detailed page.
For your comfort, we will provide in most cases Google Satellite Map links to give you an idea where the earthquake struck, which terrain it happened and if villages or cities are located in the immediate vicinity. The reference for the time zone is UTC (Coordinated Universal Time, also called GMT)
The page is regularly updated to add new earthquakes.
green color = NOT dangerous for damage or injuries
orange color = MODERATE risk for damage or injuries
red color = CONSIDERABLE risk for damage or injuries
