William B Bull

William B. Bull is an applied geologist educated at Colorado and Stanford Universities. He worked 12 years for the US Geological Survey as an engineering geologist and groundwater hydrologist. Studies of collapsing soils and land subsidence were quite appealing, but he changed career goals by moving to the University of Arizona where he taught geomorphology for 28 years. He continues to study landscapes of rising mountains from the perspective of earthquake hazards.
