    Magnitude 7.5 quake early Saturday prompts warnings

    A powerful earthquake sparked a tsunami warning for hundreds of miles of Alaskan and Canadian coastline in the early hours of Saturday morning, but the alert was canceled when no damaging waves were generated.

    The magnitude 7.5 quake and the 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 (ATWC) 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," said Sitka police chief Sheldon Schmitt. But he said things calmed down as the town waited for the all clear.

    The tremor struck at midnight Friday and was centered about 60 miles west of Craig, Alaska, the US Geological Survey said.

    "Houses shook; mine had things tossed from [the] wall," said the Craig police chief, Robert Ely. 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. The ATWC 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," 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.

    Some people in Craig also moved to safer territory.

    "Several citizens elected on their own to move to higher ground. Several locations in Craig were set up for staging [and] shelter," said Chief Ely, adding that "no evacuation was ordered".

    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.
