Tsunami warning canceled after Alaska quake

Tsunami warning canceled after Alaska quake

Officials had warned residents as far south as San Francisco to be ready to evacuate coastal areas but by 5:15 a.m. PST (1315 GMT) the U.S. National Weather Service had lifted all tsunami advisories, watches and warnings for California, Oregon Washington and Alaska.

According to the U.S. Geological Survey, there were several milder aftershocks after the quake and the epicenter was located about 6 miles below the surface and 175 miles southeast of Kodiak.

Earth sciences Prof. Brent Ward of Simon Fraser University said the quake was a strike-slip natural disaster, where the plates slip sideways past each other.

People reported on social media that the quake was felt hundreds of kilometres away, in Anchorage.

A tsunami warning for the coastal areas of B.C. has been cancelled following a magnitude 7.9 quake in Alaska. A strong quake along the Cascadia Subduction Zone, which stretches from Cape Mendocino to Vancouver Island, British Columbia, likely generated a 50-foot tsunami in Northern California.

This natural disaster prompted an immediate Tsunami Watch for California and the Humboldt County Emergency Operations Center was activated.

In a message posted to Twitter, Alaska's Gov. Bill Walker said his office is "closely monitoring" the tsunami warnings and urged residents to heed local warnings to move inland or to higher ground. One public station, KMXT in Kodiak issued an urgent advisory: "This is a tsunami warning".

Citizens of Kodiak are accustomed to hearing the tsunami sirens go off every Wednesday at 2pm during its weekly test.

"Although the tsunami warning was eventually suspended, this event demonstrates that coast warning systems do work".

"It went on long enough that you start thinking to yourself, "Boy, I hope this stops soon because it's just getting worse", Mr Athey said.

It was half past midnight on Tuesday when an natural disaster - magnitude 7.9 - struck in the Gulf of Alaska, jolting many Alaskans from their beds and sending them scrambling for higher ground as tsunami alerts were sent out across the state and down the West Coast. Two residents showed at the reception centre and another two behind municipal hall.

He pointed out there's one road out of town and it's a long ways to high ground.

Lt. Tim Putney of the Kodiak Police Department said the quake woke him up out of a dead sleep, and he estimates it shook for at least 30 seconds. The immediate reports did not reflect signs of life threatening waves or property damage.

Japan was struck by a devastating tsunami in 2011 when a 9.0-magnitude natural disaster struck 43 miles off its east coast at a depth of 18 miles.

Because of the presence of Diablo Canyon nuclear power plant, "we're actually required to demonstrate to (Federal Emergency Management Agency) that we can do this route alerting", Alsop said. Those warnings come not just on cellphones but also, in Anchorage, through a text communication system called Nixle that goes out to roughly 38,000 people.

It was originally listed at a magnitude of 8.2, but was revised to 7.9.

"I figured I'd probably just better play it safe".
