7.0 Earthquake Rocks Buildings In Alaska; No Tsunami Threat In California
ANCHORAGE, Alaska (CBS13/AP) - A 7.0 magnitude earthquake has rocked buildings in Anchorage and caused lamp posts and trees to sway, prompting people to run out of offices and seek shelter under office desks.
The U.S. Geological Survey says the earthquake Friday morning was centered about 7 miles (12 kilometers) north of Alaska's largest city.
An Associated Press reporter working in downtown Anchorage saw cracks in a 2-story building after the quake. It was unclear whether there were injuries.
People went back inside buildings after the earthquake but a smaller aftershock a short time later sent them running back into the streets again.
A tsunami warning was issued for all of Cook Inlet in Alaska, but it has since been lifted. There is no tsunami threat to California, officials say.

A 5.8 magnitude aftershock happened less than 10 minutes after the initial earthquake, according to USGS.
Photographs posted to social media sites showed damage that included collapsed ceiling tiles at an Anchorage high school and buckled roadway pavement in places.
Cereal boxes and packages of batteries littered the floor of a grocery store after the earthquake Tuesday morning that rocked buildings in Alaska's largest city, and picture frames and mirrors were knocked from living room walls.
Alaska averages 40,000 earthquakes per year, with more large quakes than the other 49 states combined.
Southern Alaska has a high risk of earthquakes due to tectonic plates sliding past each other under the region. According to the U.S. Geological Survey, the Pacific plate is sliding northwestward and plunges beneath the North American plate in southern Alaska, the Alaska Peninsula and the Aleutian Islands.
On March 27, 1964, Alaska was hit by a magnitude 9.2 earthquake, the strongest recorded in U.S. history, centered about 75 miles (120 kilometers) east of Anchorage. The quake, which lasted about 4 1/2 minutes, and the tsunami it triggered claimed about 130 lives.
