On 23–26 October 2016, the 88th annual meeting of the Eastern Section of the Seismological Society of America (ES‐SSA) was held in Reston, Virginia, jointly with the Next Generation Attenuation (NGA)‐East project. Events took place at the Sheraton Hotel in Reston. The meeting was attended by 80 registrants.
The meeting began with a field trip on Sunday, 23 October to examine the geological and earthquake engineering aspects of Washington, D.C. The field trip had 26 participants including the leaders. J. Wright Horton Jr. and J. Stephen Schindler of the U.S. Geological Survey (USGS), Reston, gave an introduction to the geology of the Washington, D.C., area, with stops at the Great Falls of the Potomac and at Rock Creek near the National Zoo. At Rock Creek, the group looked at the exposed Adam’s Mill fault, and Thomas Pratt (USGS, Reston) described the ground amplification caused by shallow deposits beneath the city measured on a recent seismometer deployment. Participants then went to the National Cathedral, where the cathedral’s Director of Preservation and Facilities, James Shepherd, and the Head Stonemason, Joe Alonso, gave a presentation about damage to the cathedral from the 2011 Mineral, Virginia earthquake, and the ongoing repairs. The group then went onto the roof of the cathedral for a first‐hand look at the damaged towers and pinnacles. Terrence Paret (Senior Principal, Wiss, Janney, Elstner Associates, Inc. [WJE]) led the group around the exterior of the cathedral to further examine the damage. The last stop was the Washington Monument, which was heavily damaged during the 2011 earthquake. Unfortunately the monument’s elevators were not functioning, which prevented the group from going inside. Nonetheless, National Park Service Ranger Robert Healy and Terrence Paret gave presentations at the base of the monument, describing its history, the earthquake damage, and subsequent repairs.
