Association of Environmental & Engineering Geologists

Date: Thursday March 19, 2015

Baltimore MD – Washington DC – Harrisburg PA

TOPIC: 2011 Virginia Earthquake and Its Significance for Seismic Hazards in the Eastern United States

A new book on “The 2011 Mineral, Virginia, Earthquake, and Its Significance for Seismic Hazards in Eastern North America” <> has chapters on a variety of geoscience and engineering aspects. The Mw ~5.8 Mineral, Virginia, earthquake of 2011 was the largest to occur in the Appalachian region in more than 100 years. It was felt over much of the eastern United States and southeastern Canada, caused significant damage from central Virginia to the National Capital Region, and was responsible for the automatic safe shutdown of a nuclear power station. It invigorated interest in earthquake processes, hazards, and preparedness along the Eastern Seaboard, and responses of the science and engineering communities to this rare event serve as models for responding to future events. The earthquake provided important new seismologic, engineering, geologic, hydrologic, and geophysical data that contribute to the understanding of earthquakes in eastern North America and to better assessment and mitigation of seismic hazards. This collection of 23 chapters makes these results available for geoscientists, engineers, and decision makers interested in understanding earthquakes and seismic hazards in eastern North America and other intraplate settings. As lead editor of the book and author of several chapters, Wright will present some highlights.

Wright is a USGS Research Geologist based in Reston, Virginia. He has years of experience in southern and central Appalachian geology, served as co-leader of the USGS Chesapeake Bay Impact Crater Project, explored and mapped pre-Cretaceous terranes and basins beneath the Atlantic Coastal Plain, and recently became involved in Virginia earthquake studies. A Fellow of the Geological Society of America, he earned a B.S. from Furman University, and M.S. and Ph.D. from the University of North Carolina at Chapel Hill.

AEG-BWH 2015 Upcoming Meetings/Field Trips
April 18 (Saturday) – AEG-BWH Spring Symposium (NEW! and at James Madison
May 21 – Mr. David Fenster (Location Vienna, VA.)

Call for presentations, AEG-BWH 2015 Spring Symposium

AEG-BWH is sponsoring a Spring Symposium on Saturday April 18, 2015. The Symposium will this year be held at James Madison University. The theme of the Symposium is: The many facets of engineering geology

There are currently 5 opportunities for students to make oral presentations. We encourage students to make oral presentations. Some can also make poster presentations. We already have 5 professionals making presentations.

Our goal is to gather together leaders and students in geo-science, geo-engineering, and related disciplines to discuss their experiences with innovative methods (applied or research) being used in today’s projects. Our hope is that, through such gatherings, the AEG community will continue to grow and better serve to protect property and the environment.

My goal is to make the conference a yearly event. I hope to make it an opportunity for those universities with geology departments with an engineering bent to showcase their achievements.

For those students who wish to just attend the symposium, the cost is nominal ($20). Scholarships are available. Students making a presentation will have a scholarship. Others may be supported when recommended by their department professors.

Below is the current program.

PGS: DC Clean Rivers Project

The March 19, 2015 meeting of the Potomac Geophysical Society will be held at the Fort Myer Officers’ Club in Arlington, VA ( in the Glassed-in room in the Fife and Drum (main dining room).

Timothy J. King, P.G. AECOM Germantown, Maryland

The DC Clean Rivers Project is an ongoing program being implemented by DC Water to reduce combined sewer overflows into the Anacostia and Potomac Rivers and Rock Creek. The Project involves construction of a series of storage and conveyance tunnels and related infrastructure to capture and subsequently treat combined sewer water from heavy rainfalls to reduce impacts to the region’s waterways.

Mr. King’s presentation will discuss the application of geophysical investigation methods to the planning and design of tunnels, shafts and related infrastructure associated with the project. Investigations have included seismic surveys to assess subsurface stratigraphy and depth to bedrock, borehole geophysical logging to characterize bedrock discontinuities, multichannel analysis of surface waves (MASW) to delineate buried channels, vertical seismic profiling for seismic design, and side-scan sonar surveys to delineate underwater obstructions.


Timothy King is a Principal Geologist at AECOM (formerly Woodward-Clyde Consultants and URS Corporation) in Germantown, Maryland. He built and is the leader of the geophysical services team at URS/AECOM. His experience includes engineering geophysics, engineering geology, and hydrogeology applied to site investigations to evaluate subsurface conditions related to tunnels, mines, highways, bridges, dams, and other civil infrastructure. He has been responsible for technical and management aspects of investigations at hundreds of sites across the United States and has worked on projects in Africa, South America, Europe and New Zealand.

Geoscience Problem Solving for Sustainability: Focus on Climate and Energy

Geoscientists are and will continue to be at the forefront of finding solutions to many of the world¹s most pressing challenges for how to find solutions to many of problems in maintaining and enhancing the quality of life for the billions of people on Earth in a sustainable manner. At the center of this challenge is the energy-climate change nexus: how to provide abundant energy to power modern society without continuing to contribute to the risk of climate change. Geoscientists are solving these problems by helping to find energy sources with lower CO2 emissions, providing the science for climate change adaptation, and exploring the prospects for climate intervention. Hand-in-hand with these issues, geoscientists need to be cognizant of the continuing need for abundant critical materials and water for alternative energy technologies and energy production.
