ANCHORAGE, Alaska – Tsunami advisories for Alaska and Hawaii were canceled Saturday after officials determined waves from a powerful earthquake in the northern Pacific were too small to pose a threat.
A tsunami of less than 4 inches (10 centimeters) was recorded Friday night at Shemya, Alaska, at the western end of the Aleutians, the National Weather Service said.
The warning prompted more than two dozen people on a remote Aleutian island to take refuge in an underground shelter.
"It's one of those situations where the indications are, when you look at Shemya and the other places in Japan, it really doesn't meet the criteria to be destructive," said National Weather Service spokesman Greg Romano.
An 8.3 magnitude earthquake struck off Japan's northern coast in the Pacific on Saturday.
