May 9 Luncheon - Geologic Hazards: Earth Fissures
Speaker: Philip Pearthree, Ph.D., State Geologist and Director of the Arizona Geological Survey.
Dr. Pearthree will present perspectives on the principal geologic hazards affecting the Central Arizona region including 1) earth fissures related to groundwater withdrawal and land subsidence; 2) flood hazards along smaller tributary washes and larger regional river systems; 3) landslides (rotational and translational landslides, major rockfalls, debris flows); 4) post-wildfire hazards, primarily flooding and debris flows; and 5) earthquake hazards.
