10. 7.6 quake jolts Alaska, triggers tsunami warning

 

Officials say a tsunami warning is in effect for parts of southern Alaska and coastal Canada after a strong earthquake shook the region.

The Alaska Tsunami Warning Center says the warning area includes coastal areas from about 75 miles southeast of Cordova, Alaska, to the north tip of Vancouver Island.

The U.S. Geological Survey says the magnitude 7.6 quake struck at midnight Friday and was centered about 60 miles west of Craig.

18. AP: Tsunami warning canceled for Alaska, Canada

JUNEAU, Alaska January 5, 2013 (AP)

Officials have canceled a tsunami warning for parts of southern Alaska and coastal Canada.

The Alaska Tsunami Warning Center says a tsunami was generated by a strong earthquake, but the waves don't pose a threat to the areas.

The center says some areas are seeing small sea level changes, but there will be no widespread destructive wave that had earlier been warned about.

The warning area included coastal areas from Cape Fairweather, Alaska, to the north tip of Vancouver Island, Canada. The area extended for more than 700 miles.

16. A tenth of the Japan quake and a hundredth of the Christmas quake, but closer.

I would think that this ones damage potential would depend on whether or not the tide is in or out.
