This video presents a visualization of how the Atwood Building in Anchorage, Alaska, shook during the Mw 7.1 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 are useful in making decisions about improving the performances of this and other buildings and the design of future buildings. Note that relative to the height of the building, the motions are magnified by a factor of 300 to show how the building deforms. Both translational (back-and-forth) and torsional (twisting) motions are observed, as well as beating effects (alternating cycles of generally increasing and decreasing levels of motion that occur when the structural damping of a building is low and when frequencies of translational and torsional motions are close).
