A large earthquake in the Aleutians today (Monday 6-23-14) posed no tsunami danger to Southeast Alaska, according to the National Tsunami Warning Center.
The magnitude 8.0 earthquake struck the Aleutians just before 1 p.m. today. It was centered about 25 miles northwest of Amchitka, at the western end of the Aleutian chain. The initial quake was followed by several aftershocks.
The earthquake prompted a tsunami warning for parts of the Aleutian chain, which was later downgraded to an advisory and then cancelled.
A small tsunami wave, of about 7 inches, was recorded in Amchitka around 3:20 p.m. Dutch Harbor recorded a wave of less than 4 inches about ten minutes later.
The Tsunami Warning Center said the depth of the earthquake limited the extent of tsunami danger. The center estimated that the quake took place at a depth of about 68 miles.
