ANCHORAGE, Alaska (AP) -- Seismologists say a strong earthquake has jolted Alaska's sparsely populated western Aleutian islands.
There are no immediate reports of injury or damage from Wednesday's earthquake. Its magnitude was initially reported as 6.9 but officials later revised that to 6.4.
The Alaska Earthquake Information Center says the quake was felt in the communities of Adak and Atka, more than 1,000 miles from Anchorage.
The quake struck at 3:39 p.m. Alaska Daylight Time, or 7:39 p.m. EDT, and was centered 71 miles southwest of Adak.
The Tsunami Warning Center in Palmer, Alaska, says there is no expectation that the quake will create a damaging tsunami.
