NIKOLSKI, ALASKA-In the early morning hours of Friday, at 1:55 am, the Aleutian Islands were rocked with a fairly large earthquake. 27 miles southwest of Amukta Island, approximately half-way between Atka and Nikolski, a 6.8 magnitude, generated at a depth 22.1 miles beneath the surface, jolted the region.

Sources gave a preliminary estimate of 7.1, but it was quickly downgraded to 6.8 as more information came available. The Pacific Tsunami Warning Center quickly analyzed the quake and determined no Tsunami threat was eminent. Affording its remote location, no damage is thought to have occurred.

The general area in which this incident took place is frequented by earthquakes every day, although a majority of them have a magnitude less than this.

There have been numerous earthquakes in the Alaska region in the past week with a majority of the larger ones taking place off-shore of Kodiak Island far out to sea. The last comparable earthquake of similar size occurred on June 23, 2011, at shortly after 6 in the evening and was located in approximately in the same place. It measured 7.2.
