To: U.S. West Coast, Alaska, and British Columbia coastal regions
From: NOAA/NWS/West Coast and Alaska Tsunami Warning Center
Subject: Tsunami Information Statement #1 issued 09/9/2011 at 12:43PM PDT

A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.

Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. Some of these areas may experience non-damaging sea level changes. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.

At 12:42 PM Pacific Daylight Time on September 9, an earthquake with preliminary magnitude 6.7 occurred 50 miles/80 Km south of Port Alice, British Columbia . (Refer to the United States Geological Survey for official earthquake parameters.)

Pacific coastal regions outside California, Oregon, Washington, British Columbia, and Alaska should refer to the Pacific Tsunami Warning Center messages for information on the event.

This will be the only statement issued for this event by the West Coast/Alaska Tsunami Warning Center unless conditions warrant. See the WCATWC web site for basic tsunami information, safety rules, and a tsunami travel time map and table. (NOTE: Travel time maps and tables indicate forecasted times only, not that a wave was generated.)

CBC.ca | Major British Columbia quake could be worse than thought - Release point of earthquake energy closer to mainland than believed

November 18, 2009 - The moderate earthquakes off the Queen Charlotte Islands Tuesday have many people once again wondering when the "big one" will hit the West Coast.

New research shows that a major quake — expected anytime in the next 200 years — could be much more devastating than previously thought.

It has been assumed for decades that the point where colliding tectonic plates would release tremendous earthquake-generating energy was about 145 kilometres off the coast of B.C. and Washington state.

But U.S. researchers using a specialized GPS system to monitor plate movement have found that the release point will be much closer to the mainland, coming within about 80 kilometres of major cities. FULL STORY>>>

Earthquake hazards

The Queen Charlotte Islands are located along the Queen Charlotte Fault, an active transform fault that produces significant earthquakes every 3–30 years. The fault is the underwater meeting of the Pacific and North American Plates along the Queen Charlotte west coast.
