The Canadian earthquake service records this as a mag 6.6 Mw in their listings, but a mag 6.3 on the details page.
Tsunami Bulletin
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.)
Whilst I do not yet subscribe to the theory that CMEs trigger earthquakes it is a subject I am investigating. In this particular instance the does seem to be a match. Here is the KP indec for the day.
Adding that to the satellite environment we get this:
This is the X-Ray flux from GOES
And here are two readings from the Magnetometer at Gakona AK. The first is the differences chart of the N, E and Z axis and the second is the Z axis only.
