Light earthquake occurs in Alaska near spot where major temblor struck over the weekend

ANCHORAGE, Alaska - A light earthquake has occurred near the spot where a major temblor struck over the weekend in Southeast Alaska.

The Alaska Earthquake Information Center says the quake occurred at 5:46 a.m. Tuesday and had a preliminary magnitude of 4.0.

It was centred 98 miles west-northwest of Craig, close to where Saturday's powerful magnitude-7.5 earthquake struck.

That earthquake prompted a tsunami warning for hundreds of miles of coastline in Alaska and Canada.

The alert was cancelled when no damaging waves were generated.

Tuesday temblor likely was an aftershock — one of several that occurred since Saturday.
