Short Biography

Dr. Thomas L. Holzer is an engineering geologist with the U.S. Geological Survey in Menlo Park, California. He has a B.S.E. degree in geological engineering from Princeton University (1965) and a M.S. degree in hydrology (1966) and a Ph.D. degree in geology from Stanford University (1970). He is a certified engineering geologist in the State of California, and a consulting professor at Stanford University in the Departments of Geological and Environmental Sciences and Civil and Environmental Engineering. He has broad experience with earthquake hazards as well as ground failure in general. He has participated in numerous post-earthquake investigations and chaired the committee that wrote The Plan to coordinate NEHRP post-earthquake investigations (2003). He has served as a consultant to the State of California during reviews of residential earthquake insurance rate applications based on earthquake loss models. He was a 2012 recipient of the Department of Interior Distinguished Service Award; the1998 Richard H. Jahns Distinguished Lecturer; and the 1995 recipient of the Distinguished Service Award from the Hydrogeology Division of the Geological Society of America.

Earthquake-induced Liquefaction Hazard Mapping and Research

Image of Current Focus for Earthquake-induced Liquefaction Hazard Mapping and Research

My current research is focussed on (1)  improving methodologies for mapping earthquake-induced liquefaction hazard, and (2) understanding the seismological implications of liquefaction caused by the 1811-1812 New Madrid earthquakes . I am developing a probabilistic approach  based on the liquefaction potential index (LPI). We have "reverse engineered" this approach to use the liquefaction observed in 1811-1812 in Arkansas and Missouri to infer the ground shaking during the earthquake and the magnitudes of these preinstrumental earthquakes.  I also have conducted extensive research on land subsidence caused by withdrawal of ground water. My particular area of interest is earth fissures and surface faulting.
