Susitna Valley earthquake felt in Anchorage

Devin Kelly

An earthquake rattled Southcentral Alaska Saturday afternoon, striking 35 miles west of Talkeetna.

The preliminary magnitude-4.8 quake hit at 5:33 p.m., according to the National Tsunami Warning Center in Palmer. On social media, people reported feeling the shaking across Anchorage -- some 80 miles southeast of the epicenter -- and in the Mat-Su Borough. However, a good number didn't notice a thing.

Chris Popham, a watchstander at the warning center, said he fielded a call from a Trapper Creek resident who said it was "shaking pretty good."

While not unusual, Popham said the tremor was "on the larger side" of day-to-day quakes.

The Talkeetna tremor comes a day after a magnitude-5.1 earthquake shook Southern California -- forcing some building evacuations in Fullerton, Calif. -- and a few days after Alaska observed the 50th anniversary of the Great Alaska Earthquake.
