A massive earthquake, — registering 7.0 magnitude according to the U.S. Geological Survey — rocked Anchorage, Alaska Friday, sending debris crashing to the ground, damaging buildings and causing “major infrastructure damage,” officials said.
The quake happened about 7.5 miles north of the city, the USGS reported, and officials said residents there should brace for aftershocks. A tsunami warning was issued but later canceled.
Those caught in the tremblor described ferocious shaking that “just didn’t stop.” It was not immediately clear if there were injuries, but Anchorage police said damage was extensive.
“There is major infrastructure damage across Anchorage. Many homes and buildings are damaged,” the department said in a bulletin. “Many roads and bridges are closed. Stay off the roads if you don’t need to drive. Seek a safe shelter. Check on your surroundings and loved ones.”
Chugach Electric, which provides power to the area, said that 21,000 customers were without electricity.
The state’s former governor, Sarah Palin, tweeted that her family’s home sustained damage.
She posted a message that started with the prayer hands emoji, and went on to write “Our family is intact – house is not… I imagine that’s the case for many, many others. So thankful to be safe; praying for our state following the earthquake.”
And President Donald Trump was briefed on the earthquake, according to a tweet from White House press secretary Sarah Sanders.
Melody Blankenship, the business director at ABC affiliate KYUR, said that there was “this sudden shaking then all of a sudden this really loud roaring noise.”
“It got to the point where we got into the doorway and it just didn’t stop,” Blankenship said.
She said that they felt an aftershock “not even five minutes later.” She said that Friday’s earthquake was “the strongest” she’s felt in the past 35 years that she has lived in Alaska.
Dr. Lucy Jones, the founder of the Dr. Lucy Jones Center for Science and Society and a former scientist at the USGS, told ABC News that “it’s a quite significant earthquake.”
She said that the quake in Alaska was about the same size as the 1989 World Series earthquake in San Francisco, which caused landslides and widespread damage, and those in Alaska “would have felt the same sort of shaking.”
One Twitter user posted a video from a local grocery store showing how shelved food was thrown onto the floor.
