A swarm of earthquakes and aftershocks hit the Aleutian Chain, just past Unalaska, on Tuesday. A couple of foreshocks were detected, then a 6.8 magnitude earthquake – which was the largest of the swarm, followed by a whole series of aftershocks. A dozen of the aftershocks came it at a 4.4 or higher, with one 6.6 magnitude shaker.
According to the Alaska Earthquake Center, the event was a “very unusual, very energetic swarm of earthquakes.”
No major damage was reported, and the earthquakes did not generate any tsunamis.
