ANCHORAGE, Alaska –Back-to-back earthquakes measuring 7.0 and 5.7 shattered highways and rocked buildings Friday 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 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 (12 kilometers) north of Anchorage, Alaska’s largest city, with a population of about 300,000. People ran from their offices or took cover under desks.
“We just hung onto each other. You couldn’t even stand,” said Sheila Bailey, who was working at a high school cafeteria in Palmer when the quake struck. “It sounded and felt like the school was breaking apart.”
A large section of an off-ramp near the Anchorage airport collapsed, marooning a car on a narrow island of pavement surrounded by deep chasms in the concrete. Several cars crashed at a major intersection in Wasilla, north of Anchorage, during the shaking.
Anchorage Police Chief Justin Doll said he had been told that parts of Glenn Highway, a scenic route that runs northeast out of the city past farms, mountains and glaciers, had “completely disappeared.”
The quake 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 in and out of the airport were suspended for hours 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.
Anchorage’s school system canceled classes and asked parents to pick up their children while it examined buildings for gas leaks or other damage.
Fifteen-year-old Sadie Blake and other members of the Homer High School wrestling team were at an Anchorage school gymnasium waiting for a tournament to start when the bleachers started rocking “like crazy” and the lights went out. People started running down the bleachers in the dark, trying to get out.
“It was a gym full of screams,” said team chaperone Ginny Grimes.
When it was over, Sadie said, there was only one thing she could do: “I started crying.”
“It’s one of those things where in your head, you think, ‘OK, it’s going to stop,’ and you say that to yourself so many times in your head that finally you think, ‘OK, maybe this isn’t going to stop,'” he said.
Soon after the shaking stopped, the school bus pulled up and children boarded, but the driver stopped at a bridge and refused to go across because of deep cracks in the road, Lettow said.
Former Alaska Gov. Sarah Palin tweeted that her home was damaged: “Our family is intact – house is not. I imagine that’s the case for many, many others.” She posted a video of the inside of her parents’ home, with broken dishes littering the kitchen floor. A large set of antlers appeared to have fallen off a wall of the living room.
Officials opened an Anchorage convention center as an emergency shelter. Gov. Bill Walker issued a disaster declaration.
He said he was in an office building elevator when the earthquake hit. Lights on the control board were blinking and things were falling from the ceiling, but the elevator did not stop, he said.
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 along Alaska’s southern coast. Police in Kodiak, a city of 6,100 people on Kodiak Island, 250 miles (400 kilometers) south of Anchorage). People were told to evacuate to higher ground immediately because a wave could hit within about 10 minutes.
Michael Burgy, a senior technician with the National Tsunami Warning Center in Palmer, Alaska, said the warning was automatically generated based on the quake’s size and proximity to shore. Scientists monitored gauges to see if the quake generated big waves. Because there were none, they canceled the warning within about an hour and a half.
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 that threw him out of the tub.
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 son’s room after the shaking stopped and found his fish tank shattered and the fish on the floor, gasping. He grabbed it and put it in another bowl.
“It was anarchy,” he said. “There’s no pictures left on the walls, there’s no power, there’s no fish tank left. Everything that’s not tied down is broke.”
Alaska was the site of the most powerful earthquake ever recorded in the U.S. The 9.2-magnitude quake on March 27, 1964, was centered about 75 miles (120 kilometers) east of Anchorage. It and the tsunami it triggered claimed about 130 lives.
The state averages 40,000 earthquakes a year, with more large quakes than the 49 other states combined. Southern Alaska has a high risk of earthquakes because the Earth’s plates slide past each other under the region.
Alaska has been hit by a number of powerful quakes over 7.0 in recent decades, including a 7.9 last January southeast of Kodiak Island. But it is rare for a quake this big to strike so close to such a heavily populated area.
David Harper was getting some coffee at a store when the low rumble began and intensified into something that sounded “like the building was just going to fall apart.” He ran for the exit with other patrons.
“People who were outside were actively hugging each other,” he said. “You could tell that it was a bad one.”
