Hundreds of aftershocks shake Alaskans following big quake

Back-to-back earthquakes measuring 7.0 and 5.7 cracked highways and rocked buildings Friday 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 reports of deaths or serious injuries.

Aftershocks Saturday continued to fray nerves. U.S. Geological Survey Geophysicist Paul Caruso said there have been 545 aftershocks, including the 5.7 magnitude shaker that came almost immediately after Friday’s big quake. Eleven have had magnitudes of 4.5 or greater.

The aftershocks should be weaker and less frequent in the coming days, but officials can’t say for sure when they’ll stop, Caruso said.

The USGS 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. The 5.7 aftershock arrived within minutes, followed by a series of smaller quakes.
