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 1811-1812 New Madrid Earthquake Series

(1811-12 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 1811-

12 Series’ conceptual model of isoseismal maps. A cumulative isoseismal map for the 1811-12 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

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

2004. 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, 2017-18 & 1989-90), 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 2011.

The New Annual Meeting Mentor Program

The Student and Young Professional Support Committee (SYPSC) is developing an annual meeting mentor program to pair professionals that plan to attend the 2018 Annual Meeting with interested student attendees. We hope mentors can provide advice and support both before and during the annual meeting to make the meeting more relaxing, enjoyable, and beneficial for students. Students interested in being paired with a mentor will identify themselves when they register for the meeting, and will be provided with the contact information of a professional who has volunteered to be a mentor. The student can then contact the professional with questions ranging from "What should I wear?" to "Could we meet during the Ice Breaker?" If you plan to attend the 2018 annual meeting and are interested in serving as a mentor to a student attendee(s), please provide your contact information and the number of students you are willing to mentor in an email to Kevin Mininger, SYPSC Co-chair.

Sample Abstract

“Your Country is Falling Apart” Response to Recent Landslides by the North Carolina Geological Survey

Bauer, Jennifer, North Carolina Geological Survey; Richard M. 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.
