LOS ANGELES, United States (AFP) — A strong 6.4-magnitude earthquake struck off the remote Andreanof Islands in Alaska on Monday but there was no immediate risk of a tsunami, authorities said.
The temblor followed a series of quakes that shook the area early in the day, including one measuring 5.9 and another measuring 5.7, according to the United States Geological Survey.
The Andreanof Islands are part of the Aleutian Islands chain in southwestern Alaska.
The area suffered a major 8.6-magnitude earthquake in 1957.
The latest quake struck 30 kilometers (18.6 miles) southwest of the Tanaga volcano.
The National Tsunami Warning Center said there was no immediate danger of a tsunami.
In 2014, a 6.1-magnitude earthquake struck Amukta island in Alaska.
