An earthquake with a reviewed magnitude of 4.5 shook Southcentral Alaska at 8:41 p.m. Tuesday.
The quake was centered 22 miles northwest of Anchorage and 18 miles south of Willow, according to the Alaska Earthquake Center. Its preliminary magnitude was recorded at 4.6.
The shaker was the latest of thousands of aftershocks to roll through the region after the 7.0 mainshock hit Nov. 30. Seismologists say these earthquakes will continue to be considered aftershocks until the region returns to pre-Nov. 30 levels of seismic activity.
