(AP Photo/Becky Bohrer) (Newser) – A magnitude 7.5 earthquake struck Alaska about midnight local time, though authorities canceled a tsunami warning for southern parts of the state and coastal Canada. The quake was centered about 60 miles west of Craig, Alaska, said the US Geological Survey. No reports of damage or flooding were initially reported. The warning area included coastal areas from Cape Fairweather, Alaska, to the north tip of Vancouver Island, Canada, more than 700 miles.
