William Schulz
I have worked as a research geologist in the Landslide Hazards Program of the U.S. Geological Survey since 2002.
Prior to that, I worked in the private sector in California and Wisconsin, mostly investigating landslides and seismogenic ground displacement. My research primarily focuses on understanding conditions that result in the diverse characteristics of landslide motion, although I am also very interested in understanding controls of the onset of landslide movement and reactivation. My work includes characterizing and monitoring landslides in the field, laboratory testing, mathematical modeling, and assessing landslide hazards.

Landslides triggered by Hurricane Maria: Assessment of an extreme event in Puerto Rico
Hurricane Maria hit the island of Puerto Rico on 20 September 2017 and triggered more than 40,000 landslides in at least three-fourths of Puerto Rico’s 78 municipalities. The number of landslides that occurred during this event was two orders of magnitude greater than those reported from previous hurricanes. Landslide source areas were commonly limited to surficial soils but also extended into und
