A moderate earthquake centered in the Gulf of Alaska shook Alaska's capital of Juneau and several other smaller cities early Monday but there were no reports of damage or injuries.

The undersea quake at 7:01 a.m. had a Richter scale magnitude of 5.2 and was centered in the Gulf of Alaska 120 miles from Juneau, said Paul Whitmore of the Alaska Tsunami Warning Center said.

The quake was felt strongly 80 miles away in Yakutat, which has been evacuated three times in the past seven months for fear of quake-caused tsunamis, but this tremor was too small to generate a seismic sea wave.
