A powerful earthquake sparked a tsunami warning for hundreds of miles of Alaskan and Canadian coastline, but the alert was canceled when no damaging waves were generated, AP reported. The magnitude 7.5 quake and tsunami warning that followed caused concern in some coastal communities, with alarms sounding and people rushing to higher ground for safety. But the Alaska Tsunami Warning Center later said the waves were too small to pose a threat, reaching just six inches above normal sea level in places such as Sitka and Port Alexander. "Initially, in the first 15 to 20 minutes, there might have been a bit of panic," Sitka Police Chief Sheldon Schmitt told The Associated Press in a phone interview. But he said things calmed down as the town waited for the all clear. The temblor struck at midnight Friday and was centered about 60 miles (95 kilometers) west of Craig, Alaska, the U.S. Geological Survey said. "Houses shook; mine had things tossed from (the) wall," Craig Police Chief Robert Ely said. But he added that there were "no reports of any injuries, no wave, no tidal movement seen." The tsunami warning was eventually expanded to include coastal areas from Cape Fairweather, Alaska, to the northern tip of Vancouver Island, Canada - an area extending more than 700 miles (1,125 kilometers). The center had warned that "significant widespread inundation of land is expected," adding that dangerous coastal flooding was possible. In its cancellation statement, the center said that some areas were seeing just small sea level changes. "A tsunami was generated during this event but no longer poses a threat," the center said. The Alaska Earthquake Information Center said the quake was widely felt but it received no reports of any damage. "It was the most intense earthquake I've felt in my 10 years here. I'm pretty sure there was stuff falling off of shelves," Chief Schmitt said. "There is no report of any wave activity here." He said that an evacuation sirens and announcements came shortly after the quake, prompting the temporary rush to higher ground.
