The northbound onramp for International Airport Rd. at Minnesota Blvd. collapsed Friday morning, Nov. 30, 2018 after a strong earthquake shook southcentral Alaska.
A magnitude 7.0 earthquake struck Friday morning near Anchorage, Alaska, causing widespread damage, triggering rock slides and alarming office workers who plunged under their desks.

Residents are reporting damage in the nearby areas via social media. One man tweeted a photo of his toppled chimney and a local television station showed its studio filled with debris. Former Alaska governor and vice presidential candidate Sarah Palin tweeted, saying her family is intact but her "house is not."

"This is a large earthquake and there have been numerous aftershocks," said John Bellini, a geophysicist for the U.S. Geological Survey. He said the largest aftershock was a 5.7 magnitude quake about six minutes after the big one.

The quake struck at 8:29 a.m. local time about seven miles north of Anchorage, the USGS reported. There were no immediate reports of injuries or deaths. Officials have since canceled a tsunami warning for coastal areas of southern Alaska.

Comment: UPDATE December 3rd

Anchorage Daily News reports that small aftershocks have continued with 1,800 measured between last Friday and Monday. A total of 153 measured greater than 3.0, 18 were at 4.0 or greater and five were greater than 5.0, according to the Alaska Earthquake Center.

Earthquakes associated with Friday's 7.0 earthquake north of Anchorage as of 5:45 p.m. Sunday. The red dots represent shakes in the previous 24 hours, and the yellow dots are from the past week (with virtually all of them since Friday. The large dot directly north of the city was Friday's quake).
UPDATE January 19, 2019

Residents in Alaska are still reporting aftershocks from the event:
The latest big aftershock happened last Sunday - a magnitude 5.0 jolt that flared already frayed nerves and prompted panicky posts on social media.

That one "reminded people again that it's not over yet," said seismologist Natalia Rupert at the Alaska Earthquake Center.

There have been more than 7,800 aftershocks since the main earthquake struck 7 miles (11 kilometers) north of Anchorage, the state's most populous city. Most were too small to feel, but 20 have had magnitudes of 4.5 or greater. Rupert expects the temblors to continue for months, although the frequency has lessened, from about 200 daily to a couple dozen a day.
