This video presents a visualization of how the Atwood Building in Anchorage, Alaska, shook during the M7.1 January 24, 2016, Iniskin, Alaska, earthquake. The building was instrumented by U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking. Such data is useful to make decisions for improving the building's performance.

Note that the visualization is magnified by a factor of 300 to show its deformation characteristics. The video of the building exhibits, translational, torsional motions, as well as beating effects.
