"My neighbor actually thought there was an alligator in the pond," said Dan Musmanno, 51, of the New Orleans suburb Belle Chasse. "My neighbor's son went out there and said, 'It ain't no alligator.' The water was going back and forth for about a half hour. It was kind of spooky."

Musmanno said the waves in his pond came up 7 or 8 inches and water sloshed out of his pool from what geophysicists say was the awesome power of a 7.9 magnitude earthquake that rocked a remote area of interior Alaska early Sunday afternoon.
