Earthquakes measuring 7.0 and 5.7 shattered highways and rocked buildings yesterday, in Anchorage and the surrounding area, sending people running into the streets and briefly triggering a tsunami warning for islands and coastal areas south of the city.
No tsunami arrived and there were no immediate reports of deaths or serious injuries.
The US Geological Survey said the first and more powerful quake was centred 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. The 5.7 aftershock arrived within minutes, followed by a series of smaller quakes.
“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.>
