Alaska earthquakes, M4-7

They had an M6 on T-day, and these stronger but not extreme quakes do occasionally occur, so a thread might be useful.

M7 on Saturday: Technically, not Alaska, but close enough and also worth watching because it is having multiple M4-5+ aftershocks. It's in a remote region and on land but things probably got knocked around since it was shallow.

Alaska Earthquake Center has a good in-depth post that starts:

On Saturday, December 6, just before noon, a magnitude 7 earthquake was felt across a 500-mile radius around the epicenter, near Hubbard Glacier, about 60 miles north of Yakutat, Alaska. At about three-quarters of a mile into Canada (Figure 1), this event technically lies outside of Alaska. Coming on the heels of a magnitude 6 near Susitna on Thanksgiving Day, and not overly long since the Sand Point magnitude 7.3 in July, the year 2025 seems determined to remind Alaskans that we live amongst an array of active faults...
