For the second time within the past week, a strong earthquake near a volcano has shaken the Aleutian Islands located between Alaska and Russia.
A 6.3-magnitude quake hit at 8:35 p.m. on August 22 (PT) about 45 kilometres (28 miles) southeast of Tanaga Volcano, Alaska, and 95 kilometres (59 miles) southwest of Adak, Alaska, at a depth of 44 kilometres (27 miles).
As a tsunami was not expected, a warning was not issued by the U.S. Tsunami Warning System.
This seismic event follows a 6.6-magnitude earthquake that struck the same area, about 50 kilometres (31 miles) south of Tanaga Volcano and 108 kilometres (67 miles) west of Adak, on August 15.
The last time Tanaga Volcano erupted was in 1914.
