5.7 magnitude quake hits Alaska

ANCHORAGE -- A strong earthquake jolted urban areas of Alaska on Monday, sending people diving under desks and huddling in doorways.

The U.S. Geological Survey said an earthquake with a preliminary magnitude of 5.7 struck near the town of Willow at 11:28 a.m. Monday. The epicenter was 58 miles from the state's largest city, Anchorage, where the rumbled continued for several moments.

The West Coast and Alaska Tsunami Warning Center reported the quake's magnitude at a slightly weaker 5.3 and said no tsunami will be generated.

There are no immediate reports of damage or injury, but the shaking was felt over a wide swatch of southcentral Alaska.

Aftershocks were shaking the area, with one about a half-hour later measuring 4.1.
