ANCHORAGE, Alaska A large earthquake rattled Alaska s seismically active Aleutian Islands, but there were no immediate reports of any damages or injuries.
The magnitude-7.2 quake struck at 11:30 p.m. Tuesday and was centered about 125 miles west of Adak in the island chain, according to a preliminary report by the U.S. Geological Survey.

The earth s most active seismic feature, the circum-Pacific seismic belt, brushes Alaska and the Aleutian Islands, where more earthquakes occur than in the other 49 States combined.
The Andreanof Island sustained a magnitude 8.8 earthquake in March 1957 that caused very severe damage on Adak and Unimak Islands. A damaging tsunami was generated, and a wall of water 40 feet high smashed the coastline of Scotch Cap on Unimak Island. Sand Bay, near Adak, reported 26-foot waves inundated its shores.
