Enhanced landslide mobility by basal liquefaction: The 2014 State Route 530 (Oso), Washington, landslide

Informational Challenges in Early Disaster Response: The Massive Oso/SR530 Landslide 2014 as Case in Point

In disasters, and more so in catastrophes, one of the most daunting problems to professional responders is gaining situational awareness. Unfortunately, truly actionable information (intelligence) is missing in the first days and even weeks of responding. Consequently, incomplete situational awareness brings on a distorted common operating picture leading to suboptimal direction of responses, s...

Landslide basal friction as measured by seismic waves

[1] Dynamical predictions of landslide runout require measurements of the basal friction. Here we present the first seismically determined bounds on the frictional coefficients for three large volcanic landslides. The three landslides (Bezymianny, Russia 1956, Sheveluch, Russia 1964 and Mount St. Helens, USA 1980) have masses that vary by a factor of 5 and were all followed immediately by erupt...

Use of a Small Unmanned Aerial System for the SR-530 Mudslide Incident near Oso, Washington

The Center for Robot-Assisted Search and Rescue deployed three commercially available small unmanned aerial systems (SUASs)—an AirRobot AR100B quadrotor, an Insitu Scan Eagle, and a PrecisionHawk Lancaster—to the 2014 SR-530 Washington State mudslides. The purpose of the flights was to allow geologists and hydrologists to assess the eminent risk of loss of life to responders from further slides...
