Watch the Atwood building sway from the 7.0 earthquake

ANCHORAGE (KTUU) - A new video, uploaded by the U.S. Geological Survey, shows an amplified look at how the Atwood building bobbed and weaved during the 7.0 magnitude earthquake on Nov. 30th.

The video, posted on YouTube, shows a computer generated replica of the building, one of the tallest in Anchorage.

It twists and sways. The movements are magnified 100 times, which makes it easier to understand how the quake impacted the building. USGS says although the images are magnified, the movement itself is unchanged from the day of the quake.

Shortly after 8:30 in the morning, the Atwood building seems to sway strongly from East to West.

"The motions in East-West directions are stronger in this particular earthquake and I think that's due to the seismic waves come and hit the building," Mehmet Celebi with the USGS said.

When it's compared to the 7.1 earthquake from Jan. 2016, the building at that time moved in a more circular pattern.

Celebri says engineers will use the information to improve building codes, design stronger structures and learn even more about earthquakes.
