1 April 2018 May 12, :30 7:30+/- Gregory L. Hempen, PhD, PE, RG, AEG National President Presenting: ARE YOU READY FOR THE BIG ONE? Important Considerations for US Seismicity and An Update on AEG National Activities Meeting Location at the Red Robbin in Murray (see below) Abstract: As all local geologists know, the Wasatch Fault runs along the eastern margin of the populated areas in Utah. This fault is believed capable of generating magnitude 7 or greater earthquakes in our backyards. Dr. Greg Hempen will discuss recent research for the New Madrid Seismic Zone (NMSZ) that allows new interpretations of historic earthquakes and evaluations to assist the public with the preparedness for, and response to, potential earthquakes. Paleoseismic studies and development of earthquake source and wave passage modeling have allowed a new assessment of historic events. These assessments, in turn, may be used to develop government, business and general public approaches to seismic-hazard preparedness and response. Paleoseismic studies of the NMSZ provide insight into the recent millennia s historic events. Assembling the paleoseismic assessments with the historic data for the New Madrid Earthquake Series ( Series) gives a fresh interpretation of the severity and number of daily interplate tremblers. The use of regional geologic data and modeling of site response allowed our development of the Series conceptual model of isoseismal maps. A cumulative isoseismal map for the Series also has been prepared. The isoseismal maps provide median hazards. The hazard in any location may have been much worse or much less. Probabilistic and deterministic seismic models can be used to portray the seismic hazard with these 1

2 new interpretations. Such seismic models can be used to inform businesses, governments and the general public of the hazard and risk of earthquake impacts. The presentation considers some actions to inform the public of appropriate preparedness with these modeled seismic risks. Bio: Greg is a Geophysicist / Geological Engineer, who specializes in all types of vibration mitigation from earthquakes, blasting and pile driving, and recommending appropriate geophysical studies for complex sites. His 40+-year career includes a long tenure at, and retirement from, the St. Louis District, Corps of Engineers. Greg has conducted business for all levels of government, federal, state and local. He had worked closely with consulting firms managing studies on federal projects. He now works in the private sector, but continues studies for federal and state offices. His duties have included: site assessment of dam sites, regional earthquake studies for federal dam sites, probabilistic and deterministic appraisal of potential earthquake impacts, varied geophysical studies for different projects concerns (from archeological to environmental transport to groundwater to rock weaknesses), blast mitigation while effectively achieving the blasting goal, environmental mitigation, and the dreaded other duties, as assigned. Greg received a B.S. in Geophysical Engineering from St. Louis University, a M.S. in Geo- Engineering from the University of Minnesota, Minneapolis-St. Paul, and a Ph.D. in Geological Engineering from the University of Missouri - Rolla (now Missouri University of Science & Technology). He is a Registered Professional Engineer and Registered Professional Geologist in Missouri. Greg has authored a variety of publications, which share the understanding of procedures instead of keeping proprietary control of methodologies. Greg has been an adjunct professor at all the engineering universities in the St. Louis area. He has taught Environmental Science classes and Geotechnical Engineering courses. His longest running class was offered once a year, Seismology and Seismic Design (CE 530A), Civil Engineering Department, Washington University of St. Louis, 1989 to Greg had taught at several Corps of Engineers professional training courses. Several causes have gained Greg s attention over the years. He has long been active with AEG (President, & ), and GSA s EEGD. He had a minor role in developing the administration of the Jahns Lectureship. He is also active with several other professional organizations. Greg has been involved with the pursuit of several important public issues, including Geologists Registration, public disaster preparedness, and building-code adoption. He has served on state commissions, and is presently serving on a Missouri State organization. Some of the accolades that Greg has received are: Honorary Member from AEG, September 2014; a Professional (Honorary) Degree from Missouri University of Science & Technology, December 2010; a Presidential Award (POTUS) with the Army and Corps team for the Embrey Dam Removal, May 2004; Achievement Medal for Civil Service, December 1998; Johnston Service Award from AEG, October 2002; 1991 Regional Outstanding Engineer from the Missouri River Region of the Society of American Military Engineers; and, the Otto Nuttli Award from the St. Louis Section of the American Society of Civil Engineers, October

Wooten; Kenneth A. Gillon; Thomas J.Douglas. Since August 2009, the mountains of Western North Carolina have received 42 inches of rainfall, 16 inches above normal, relieving the region of a two-year drought. These rain events have also increased soil moisture, raised groundwater levels, and triggered over 40 landslide events in the region. As part of its commitment to public safety, the North Carolina Geological Survey has responded to fifteen of these events to evaluate slope stability and provide information to assist state and local agencies and the public. These response efforts have included requests from emergency management officials, erosion control officers, and town planners concerned about the life, health, safety and property of their citizens. Response activities include stability assessment and monitoring of sites during recovery and clean-up efforts; assisting in determining the nature and extent of the slope failures; mapping the affected area and areas that could be affected (e.g. hazard zonation and debris flow inundation modeling), making Geographic Information System (GIS) maps to assist emergency management officials in their response and contingency planning; and communicating findings to the appropriate officials, public, and the media. Mapping and data collected at these sites is incorporated into a slope movement-slope movement deposit geodatabase. All of the slope movements to which the NCGS responded occurred on slopes that have been modified in some way by human activity; four of them have damaged six structures and four threaten homes, one of which has been condemned. This paper will illustrate several of these landslide investigations and responses, as well as give a brief timeline of rainfall events correlating to these slope failures. 10
