ANCHORAGE, Alaska (AP) — Back-to-back earthquakes measuring 7.0 and 5.7 shattered highways and rocked buildings 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 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, Alaska's largest city, with a population of about 300,000. People ran from their offices or took cover under desks.
"It had my heart racing and I felt a bit of motion sickness afterwards. I was scared!" April Pearce wrote on Instagram after being shaken at her desk in the town of Soldotna.
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 the Glenn Highway, a scenic route that runs northeast out of the city past farms, mountains and glaciers, had "completely disappeared."
