A moderate-sized earthquake occurred near Unalaska early this morning.
The 4.0-magnitude earthquake happened on the Pacific side of the island, nearly 40 miles from town. It struck at around 3am, and occurred at a depth of 21 miles below the earth’s surface.
And just down the Aleutian Chain, another 4.3-magnitude four earthquake hit about 15 miles from Atka. That earthquake occurred just after midnight.
The Alaska Earthquake Center received no felt reports from area residents following either one of the earthquakes, says seismologist Natasha Ruperts. She adds that seismic activity is common along the Aleutian Chain and that neither one of these earthquakes is considered unusual.
