Soft cover. Condition: New. 68 pages. The Chesapeake Bay impact structure is perhaps the best documented example of a small group of multi-layer, marine-target impacts formed in continental shelves or beneath epeiric seas. In this multidisciplinary study, new sedimentological and stratigraphical data and results mainly from three Chesapeake Bay brim cores (Watkins School, Langley, and Bayside) are compared to and compiled with key crater core data. This volume provides detailed understanding of the impact-related processes and sedimentation, their interaction and relative timing, and their products in the "brim," the target-sediment layer in the area outside the transient cavity.

The magnitude ~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.
