7.5-magnitude earthquake near Alaska generates small tsunami

The magnitude 7.5 earthquake near Sand Point, Alaska, generated a tsunami, Scott Langley with the National Tsunami Warning Center said Monday afternoon.Langley said the tsunami sent two waves, each measuring 4 feet, 3 inches high. But observers onshore reported the waves appeared to be 1.5 feet and 2 feet over high tide.The center is monitoring harbors in a 500-mile area along the Alaska coastline, he said.A tsunami warning had been issued after the earthquake struck, but it was downgraded to an advisory Monday afternoon.The advisory was for the Alaska Peninsula and South Alaska, according to the tsunami warning center in Palmer, Alaska.Langley said earlier the area subject to the warning and advisory is “pretty remote.””For other U.S. and Canadian Pacific coasts in North America, there is no tsunami threat,” the center said.The earthquake’s epicenter was recorded less than 60 miles from Sand Point, near the Aleutian Peninsula in the southwestern part of the state.”We did feel it,” Sand Point Clinic employee Lorna Osterback said of the quake. “This is a big one.”Osterback said residents of the town would be heading to higher ground away from the shoreline as they wait out the tsunami threat.”We expect we will have another one in about half an hour,” noted Osterback. “We’re right on the fault line. I grew up here and it’s kind of normal.”Residents of Homer could also be seen driving to higher ground.Several aftershocks, including one with a magnitude of 5.9 and one that was 5.8, struck in the hour after the big quake.

The center is monitoring harbors in a 500-mile area along the Alaska coastline, he said.

A tsunami warning had been issued after the earthquake struck, but it was downgraded to an advisory Monday afternoon.

The advisory was for the Alaska Peninsula and South Alaska, according to the tsunami warning center in Palmer, Alaska.

Langley said earlier the area subject to the warning and advisory is “pretty remote.”

“For other U.S. and Canadian Pacific coasts in North America, there is no tsunami threat,” the center said.

The earthquake’s epicenter was recorded less than 60 miles from Sand Point, near the Aleutian Peninsula in the southwestern part of the state.

“We did feel it,” Sand Point Clinic employee Lorna Osterback said of the quake. “This is a big one.”

Osterback said residents of the town would be heading to higher ground away from the shoreline as they wait out the tsunami threat.

“We expect we will have another one in about half an hour,” noted Osterback. “We’re right on the fault line. I grew up here and it’s kind of normal.”

Residents of Homer could also be seen driving to higher ground.

Several aftershocks, including one with a magnitude of 5.9 and one that was 5.8, struck in the hour after the big quake.
