Earthquake hazard in the heart of the homeland Earthquake hazard in the heart of the homeland
Evidence that earthquakes threaten the Mississippi, Ohio, and Wabash River valleys of the Central United States abounds. In fact, several of the largest historical earthquakes to strike the continental United States occurred in the winter of 1811-1812 along the New Madrid seismic zone, which stretches from just west of Memphis, Tenn., into southern Illinois. Several times in the past...

Facing tomorrow’s challenges—U.S. Geological Survey science in the decade 2007–2017 Facing tomorrow’s challenges—U.S. Geological Survey science in the decade 2007–2017
Executive Summary In order for the U.S. Geological Survey (USGS) to respond to evolving national and global priorities, it must periodically reflect on, and optimize, its strategic directions. This report is the first comprehensive science strategy since the early 1990s to examine critically major USGS science goals and priorities. The development of this science strategy comes at a time...

Urban seismic hazard mapping for Memphis, Shelby County, Tennessee Urban seismic hazard mapping for Memphis, Shelby County, Tennessee
Earthquakes cannot be predicted, but scientists can forecast how strongly the ground is likely to shake as a result of an earthquake. Seismic hazard maps provide one way of conveying such forecasts. The U.S. Geological Survey (USGS), which produces seismic hazard maps for the Nation, is now engaged in developing more detailed maps for vulnerable urban areas. The first set of these maps...

First USGS urban seismic hazard maps predict the effects of soils First USGS urban seismic hazard maps predict the effects of soils
Probabilistic and scenario urban seismic hazard maps have been produced for Memphis, Shelby County, Tennessee covering a six-quadrangle area of the city. The nine probabilistic maps are for peak ground acceleration and 0.2 s and 1.0 s spectral acceleration and for 10%, 5%, and 2% probability of being exceeded in 50 years. Six scenario maps for these three ground motions have also been...

Liquefaction induced by historic and prehistoric earthquakes in western Puerto Rico Liquefaction induced by historic and prehistoric earthquakes in western Puerto Rico
Dozens of liquefaction features in western Puerto Rico probably formed during at least three large earthquakes since A.D. 1300. Many of the features formed during the 1918 moment magnitude (M) 7.3 event and the 1670 event, which may have been as large as M 7 and centered in the Añasco River Valley. Liquefaction features along Río Culebrinas, and possibly a few along Río Grande de...

Evidence for New Madrid earthquakes in A.D. 300 and 2350 B.C Evidence for New Madrid earthquakes in A.D. 300 and 2350 B.C
Six episodes of earthquake-induced liquefaction are associated with soil horizons containing artifacts of the Late Archaic (3000-500 B.C.) and Early to Middle Woodland (500 B.C.-A.D. 400) cultural periods at the Burkett archaeological site in the northern part of the New Madrid seismic zone, where little information about prehistoric earthquakes has been available. Radiocarbon dating of...
