EAGLE RIVER, Alaska — Rebecca Boddy awoke to what she thought was the sound of her garage door opening but once her house began shaking, she realized it was an earthquake.

On Friday, Anchorage was hit by a magnitude 7.0 earthquake and hundreds of tremors, according to the U.S. Geological Survey. Seven minutes after the first major hit, a magnitude 5.7 earthquake occurred, according to the agency. And Sunday, the agency registered 162 aftershocks of magnitude 3.0 or above.

“I woke up out of a dead sleep to that happening,” said Boddy, a nurse whose parents live in Mars.

“This is no exaggeration: The entire house was rocking back and forth. The dogs are going nuts. I hear glasses breaking everywhere.

“It was the most terrifying experience of my life,” said Boddy, who is pregnant. “It only lasted 30 seconds or so but it felt much longer than that.”

With a population of nearly 300,000, Anchorage is Alaska’s largest city.

Earthquakes are common in Alaska, which is part of the Ring of Fire region, a large region from South America to New Zealand marked by volcanoes and earthquake sites. Anchorage’s last major quake occurred in 1964, according to reports, killing 131 people. And since that quake, Alaska has experienced 144 quakes above magnitude 6, according to USGS.

“Even as we recover from the impact this event had on our families, friends, and neighbors, USGS is leading post-earthquake surveys and investigations,” said Aimee Devaris, USGS Regional Director for Alaska. “This research will allow us to build on our scientific understanding of earthquake hazards and how best to plan for, respond to, and recover from large earthquakes.”

Nobody was killed in Friday’s quake but the area didn’t go unharmed. Boddy, who lives near Anchorage in Eagle River, observed that traffic across the area was heavy, with cars navigating large potholes created by the quake in some cases and being rerouted away from collapsed roads in the worst situations.

And the area is likely to continue to be active over the next few days. According to USGS, there is a small chance that one of the aftershocks will hit the magnitude 7.0 mark with many other smaller quakes expected.

Boddy’s husband, Jacob, is enlisted in the Air Force and his duties forced them to relocate in July from Florida to Alaska.

Boddy said their home lost power during the earthquake but it was restored later that afternoon.

“People who have been here their whole lives are terrified,” Boddy said. “We’re still getting aftershocks today.”
