The Alaska Earthquake Information Center reports that an earthquake that shook Southcentral and Interior Alaska for several seconds Thursday at 9:51 a.m. had a preliminary magnitude of 6.24, not 6.1 as originally reported.

The National Weather Service originally said the temblor was located 60 miles southwest of Talkeetna at a depth of 98 kilometers, although the Alaska Earthquake Information Center later updated the depth to 103 kilometers (64 miles); according to the Alaska Tsunami Warning Center, a tsunami is not expected.

Seismologist Natalia Ruppert at the Alaska Earthquake Information Center said the quake was caused by the Pacific plate diving under the North American plate; its depth, she said, will have minimized its impact.

"This was quite deep, so I wouldn’t expect any serious damage," Ruppert said. "Deep earthquakes normally don’t produce as many aftershocks as shallow earthquakes, so there will be some aftershocks, but I don’t expect there to be too many."

While Anchorage residents felt multiple jolts, and buildings shook for long after the earth stopped moving, Ruppert said the quake officially lasted just 10 seconds.
