The United States Geological Survey recorded a 7.0 earthquake centered about nine miles north of Anchorage, Alaska, Friday. The quake struck at 8:30 a.m. local time (10:30 Mountain Time) and has been followed by at least at least nine aftershocks measuring 3.4 or greater on the Richter Scale. The strongest aftershock measured 5.7.
The earthquake occurred at a depth of more than 25 miles beneath the surface and prompted a tsunami warning for the Cook Inlet area and southern Kenai Peninsula. The warning was later cancelled.

Social media lit up with reports of damage throughout the area, including a number of roads that had buckled and cracked. Some store shelves and their contents tumbled into aisles.
No deaths have been reported so far. Television station KTVA reported that power was out in some areas. Station staff had been evacuated from their building, which showed extensive damage during live reports from just outside the facility.
