ANCHORAGE, Alaska (AP) Back-to-back earthquakes measuring 7.0 and 5.7 rocked buildings and shattered roads Friday morning in Anchorage, sending people running into the streets and briefly triggering a warning to residents in Kodiak to flee to higher ground for fear of a tsunami.
The tsunami warning was lifted without incident a short time later. There were no immediate reports of any deaths or serious injuries.
The U.S. Geological Survey said the first and more powerful quake was centered about 7 miles north of Anchorage, Alaskas largest city, with a population of about 300,000. People ran from their offices or took cover under desks.
A large section of road near the Anchorage airport collapsed, marooning a car on a narrow island of pavement surrounded by deep chasms in the concrete.
The shaking broke store windows, opened cracks in a two-story building downtown, disrupted electrical service and disabled traffic lights, snarling traffic. It also threw a full-grown man out of his bathtub.
All flights were halted at the airport after the quake knocked out telephones and forced the evacuation of the control tower, and the 800-mile Alaska oil pipeline was shut down while crews were sent to inspect it for damage.
Anchorages school system canceled classes and asked parents to pick up their children while it examined buildings for gas leaks or other damage.
Officials opened an Anchorage convention center as an emergency shelter. Gov. Bill Walker issued a disaster declaration.
Cereal boxes and packages of batteries littered the floor of a grocery store, and picture frames and mirrors were knocked from living room walls.
People went back inside after the first earthquake struck, but the 5.7 aftershock about five minutes later sent them running back into the streets. A series of smaller aftershocks followed.
A tsunami warning was issued for the southern Alaska coastal areas of Cooks Inlet and part of the Kenai peninsula. Kodiak police on Kodiak Island warned people in the city of 6,100 to evacuate to higher ground immediately because of wave estimated 10 minutes.
Michael Burgy, a senior technician with the National Tsunami Warning Center in Palmer, Alaska, said the tsunami warning was automatically generated based on the quakes size and proximity to shore. Scientists monitored gauges to see if the quake generated big waves. Because there were none, they canceled the warning.
In Kenai, southwest of Anchorage, Brandon Slaton was alone at home and soaking in the bathtub when the earthquake struck. Slaton, who weighs 209 pounds, said it created a powerful back-and-forth sloshing in the bath, and before he knew it, he was thrown out of the tub by the waves.
His 120-pound mastiff panicked and tried to run down the stairs, but the house was swaying so much that the dog was thrown off its feet and into a wall and tumbled to the base of the stairs, Slaton said.
Slaton ran into his sons room after the shaking stopped and found his fish tank shattered and the fish on the floor, gasping for breath. He grabbed it and put it in another bowl.
