WASHINGTON, July 18 (Reuters) - A 6.7 magnitude earthquake struck off the coast of Alaska on Sunday, but no widespread threat of a tsunami was seen, according to the Pacific Tsunami Warning Center.
The earthquake was centered 27 miles (43 km) west of Nikolski in the Aleutian island chain at a depth of 21.7 miles (35 km).
"A widespread destructive tsunami threat does not exists based on historical earthquake and tsunami data," the Center said in an email.
