Another milestone for Alaska: 2018 marks the first time the state has recorded 50,000 earthquakes in a calendar year. As of tonight, more than 50,036 earthquakes were recorded by the Alaska Earthquake Center, which has an earthquake counter at the bottom of its page.
Today’s largest quake so far was 4.2 magnitude. It was the largest in days and was centered 19 miles northwest of Anchorage in the Big Lake area, in the same general location as the 4.8 aftershock that occurred Dec. 9.
At least 4,000 aftershocks have been recorded since the Nov. 30 earthquake. At least two dozen of them have registered over 4.0.
