Southcentral Alaska was rattled by a magnitude 7.0 earthquake that struck at 8:29 Friday morning. The earthquake was centered just 7 miles north of Anchorage and was only 27 miles deep.

The high magnitude, nearby location, and shallow depth all combined to create a destructive situation for Anchorage and the Mat-Su. It was strong enough to collapse roads, cause landslides, break water and gas lines in addition to causing exterior and interior damage to area buildings.

Since the initial quake, there have been hundreds of aftershocks. Aftershocks will likely continue for days and weeks to come.


The U.S. Geological Survey estimates the chance of an earthquake of magnitude 5 or higher is 88 percent with as many as eight aftershocks possible. We have already seen three aftershocks of this level.

They say the chance of an earthquake of magnitude 6 or higher is 24 percent, but the chance of an earthquake of magnitude 7 or higher is only 3 percent.

The last quake of this magnitude to shake Anchorage was almost 3 years ago in 2016 when a 7.1 magnitude struck, although that quake was more than 160 miles outside of Anchorage and was much deeper at almost 75 miles below the earth's surface. 

 Stay tuned to the KTVA Weather Team for updates on additional aftershocks through the weekend.
