The Oso Landslide of 2014 devastated a community near the Stillaguamish River in Washington, leaving lawsuits and deaths in its wake. This disastrous event raised important questions regarding landslide prediction, mitigation, and future land use. Now, current technology allows researchers like UW’s Sean Lahusen to dig beneath the surface to find hidden clues left from landslides in years past, which can reveal a region’s vulnerability to future landslides.
