The large landslide that occurred on March 22, 2014 near Oso, Washington was unusually mobile and destructive. The first published study from U.S. Geological Survey investigations of the Oso landslide reveals that the potential for landslide liquefaction and high mobility are influenced by several factors, and the landslide process at Oso could have unfolded very differently (with much less destruction) if initial conditions had been only subtly different.
