Here is your weekly seismic update from the Alaska Earthquake Center for the week of January 7, 2026, where earthquake activity is monitored 24 hours a day.
This Week’s Earthquake Activity
Over the past week, about 1,100 earthquakes were recorded across Alaska. Eight of these were felt by residents.
Around 600 earthquakes were aftershocks from the magnitude 7.0 Hubbard Glacier earthquake that struck Southeast Alaska on December 6.
The largest earthquake this week was a magnitude 5.7 aftershock that occurred on New Year’s Eve.
Alaska’s Earthquakes in 2025
In total, Alaska recorded 31,096 earthquakes in 2025. Activity increased toward the end of the year due to the strong aftershock sequence following the Hubbard Glacier earthquake.
Despite several large earthquakes, no major damage was reported statewide.
Notable Earthquakes in 2025
- July 16: A magnitude 7.3 earthquake offshore of the Alaska Peninsula, south of Sand Point, was felt as far away as Anchorage and Juneau. This was the fifth magnitude 7 or larger earthquake in that area since 2020.
- July 29: A massive magnitude 8.8 earthquake off the coast of Kamchatka, Russia, triggered tsunami warnings across the Pacific. Alaska experienced only minor effects, with the highest wave reaching 2.7 feet in Adak. The event showed how distant earthquakes can still affect Alaska.
- August 10: Large waves were reported near Tracy Arm Fjord, south of Juneau. Scientists quickly analyzed seismic data and identified a major landslide, later confirmed through field studies. The resulting tsunami was the second-highest ever recorded, behind only the famous 1958 Lituya Bay tsunami.
