The Oso landslide, also known as the SR 530 landslide, occurred in northwest Washington state on March 22, 2014, leading to devastating loss of life and destruction of property. Oso was emblematic of a worst-case landslide scenario. As such, U.S. Geological Survey scientists have identified it as a key geological-hydrological event that can help explain and inform our understanding of the potential effects of landslides in other settings.
