Anchorage Office Building Shaking Visualizations
These videos presents a visualization of how the Frontier Building, Atwood Building and BP Building in Anchorage, Alaska, shook during the moment magnitude (Mw) 7.1 November 30, 2018, Anchorage, Alaska, earthquake. The buildings were 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 performance of this and similar buildings.
