This cover contains locations of two COCORP lines that cross the study area.
This cover contains the location of global positioning system stations that are located within the project boundary. Several GPS networks with various monument spacings are being used to monitor deformation in parts or all of the Mississippi embayment. On
This cover includes seismic reflection lines that have geophysical cross-sectional interpretations constraining subsurface structures that may penetrate to hypocentral depths. Lines were gathered from theses, dissertations, and publications.
This cover includes seismic refraction lines that have geophysical cross sectional interpretations constraining subsurface structures that may penetrate to hypocentral depths. Lines were gathered from theses, dissertations, and publications.
This cover contains the locations of stations deployed in the temporary network by M.W. Hamburger, G.L.Povlis, and others at Indiana University from October 1995 through June 1996. 20 three-component digital instruments were deployed near the Wabash River
This data set shows the locations of stations, samples, photographs and videos collected by the U.S. Geological Survey in the New York Bight on four research cruises carried out between 1996 and 2000.
This cover contains station locations of the New Madrid Seismic Network within the study boundary. The network is a cooperative project of Saint Louis University and Memphis State University. Operation of the network has been continuous since June 1975, b
Lines in this cover show where gravity oe aeromagnetic data have been modelled to constrain subsurface structure. Gravity and magnetic signatures result from deep structure, such as might be at hypocentral depths of earthquakes. We show only the lines for
Magnetotelluric soundings give data that can help define the l electricamagnetic properties of rocks, and with other geophysical data help define the structure of the shallow crust where earthquakes occur. The sounding points in this cover show where data
NOTE: Location of one point, near -88.65, 38.95, was incorrect when Sheet A was published. The location is .5 degree south, and is corrected in this dataset. This cover contains locations of places where greatest horizontal compressive stress (S(Hmax)) o
This cover contains locations of strong motion accelerograph instruments located in the lower Wabash Valley. The instruments are operated by Lamont-Doherty Geological Observatory, the University of Kentucky, and the U.S. Army Corps of Engineers Strong Mot
