During the week of October 10, 2022, the Alaska Earthquake Center reported 949 earthquakes within the state. The largest earthquake was magnitude 4.8 that occurred on October 9 at 16:54:02 AKST, 17 miles SE of Yunaska Island in the Fox Island region of the Aleutian Islands.

Other notable events include two felt earthquakes on October 10: a magnitude 4.2 earthquake located 52 miles N of the capital city Juneau that was felt in the SE Alaska and a magnitude 4.4 earthquake in the Cook Inlet region that was felt in Kenai Peninsula communities. These two events occurred within several hours of each other.

There were 60 ice quakes reported, half of which were located within the Wright Glacier cluster region NE of Juneau. This activity is seasonal and we expect it to diminish in the coming weeks.
