Sitka, Alaska, United States (4E) – A powerful earthquake struck about 60 miles of Alaska, according to the United States Geological Services.
The earthquake ensued a tsunami warning for hundreds of miles of Alaskan and Canadian coastline, but the alert was later canceled .
The quake struck at midnight Friday .
A tsunami warning came minutes later and was eventually expanded to include coastal areas from Cape Fairweather, Alaska, to the northern tip of Vancouver Island, Canada. The area extends for more than 700 miles.
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.
No damages were reported as the result of the quake.
