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.

A tsunami warning is in effect for parts of southern Alaska and coastal Canada after a strong earthquake shook the region at midnight Friday.

The warning area includes coastal areas from about 75 miles southeast of Cordova, Alaska, to the north tip of Vancouver Island, Canada, the Alaska Tsunami Warning Center said. The warning area extends for about 475 miles.

The magnitude 7.5 quake struck at midnight Friday (1 a.m. PST Saturday) and was centered about 60 miles west of Craig, Alaska, the U.S. Geological Survey said.

A tsunami with a "significant widespread inundation of land is expected," the center said in a statement.

The first wave was expected around 1:15 a.m. (2:15 a.m. PST) in Craig, and 2:50 a.m. in Cordova, further to the north.

The center said widespread dangerous coastal flooding is possible.

In addition to the warning, a tsunami advisory is in effect for coastal Alaska from Cape Suckling to 75 miles southeast of Cordova and from the Washington state border to the tip of Vancouver Island.

A tsunami warning means an area is likely to be hit by a wave, while an advisory means there may be strong currents, but that widespread inundation is not expected to occur.
