A large aftershock with a reviewed magnitude of 4.7 jolted Southcentral Alaska on Thursday evening, according to the Alaska Earthquake Center.

The earthquake, which struck at 5:33 p.m. about 19 miles north of Joint Base Elmendorf-Richardson, was the largest one in almost two weeks, the earthquake center said. An aftershock with a reviewed magnitude of 5.0 aftershock also shook Anchorage on New Year’s Eve.

Thousands of aftershocks have shaken the region since the magnitude 7.0 earthquake on Nov. 30. Seismologists at the Alaska Earthquake Center have said the aftershocks will likely continue for months and may last as long as a year.
