The U.S. Geological Survey says a strong earthquake hit Alaska's Aleutian Islands Saturday at 12:24 pm local time. The quake measured in at a magnitude 6.2. Its epicenter was about 84 miles west-northwest of Adak, Alaska or 110 miles northeast of Amchitka, Alaska. It was centered about 80 miles deep.
The quake occurred along a fault line where two of earth's oceanic plates are sliding together. It occurred on the ridge side of the fault, where the volcanic Aleutian Islands are located. South of the islands is a subduction zone, marked by an ocean trench. These types of geological set-ups are often the location of the most powerful earthquakes, many of which generate tsunamis.
NOAA's Pacific Tsunami Warning Center says no tsunami was generated by the earthquake, though enhanced wave action due to underwater landslides caused by the intense shaking is possible on a local scale.
There were no immediate reports of damage or injuries.
