Yakutat, AK – A series of earthquakes has been shaking the region north of Yakutat throughout the weekend, with three quakes recorded Sunday alone as part of an emerging seismic swarm. While no damage or tsunami threats have been reported, monitoring agencies say the activity is notable even for this earthquake-prone area.
According to the Alaska Earthquake Center and the U.S. Geological Survey, the latest event—a magnitude 2.8 earthquake—struck at 16:55 UTC (7:55 a.m. AKST) about 94 km north of Yakutat at a depth of 5 km. The quake is the newest addition to a cluster of seismic events concentrated along the Yakutat microplate boundary.
Just minutes earlier, a magnitude 4.4 earthquake occurred 111 km north of Yakutat, recorded at 12 km deep. Earlier in the morning, a magnitude 3.5 quake hit 98 km north of the city, registering a depth of 5 km.
Seismologists classify multiple shallow quakes occurring in a tight time window as swarm-like activity, a pattern consistent with Yakutat’s complex tectonic interactions. While such swarms are generally not dangerous, they can occasionally precede larger earthquakes.
Despite the uptick in seismic movement, the National Tsunami Warning Center issued a statement confirming no tsunami danger for Alaska, British Columbia, or the U.S. West Coast.
No felt reports have yet been submitted for the newest quakes, though light shaking was possible in remote parts of northern Southeast Alaska. Officials encourage residents to submit “Did You Feel It?” reports to help refine intensity estimates.
More small quakes may continue as the swarm progresses, but no hazardous impacts are currently expected.
