Open-File Report 2013–1004
AbstractOn March 4, 2011, 26 researchers gathered in Norwood, Massachusetts, for a workshop sponsored by the U.S. Geological Survey and FM Global to discuss geodesy in and around the New Madrid seismic zone (NMSZ) and its relation to earthquake hazard. The group addressed the challenge of reconciling current geodetic measurements, which show low present-day surface strain rates, with paleoseismic evidence of recent, relatively frequent, major earthquakes in the region. Several researchers were invited by the organizing committee to give overview presentations while all participants were encouraged to present their most recent ideas. The overview presentations appear in this report along with a set of recommendations. |
