This cover contains faults in the unconformity at the Cambrian-Precambrianboundary. These data were contributed byGlenn Bear of Indiana University as part of the work onhis doctoral thesis. The southern part of the map was produced byJames Drahovzal of the Kentucky Geological Survey and merged withBear's map of the rest of the map area and beyond.Public and proprietary seismic reflection and welldata were used to define the basement structure.A prominent east-west structure in the southern half of the maparea is the western end of the Rough Creek Graben. At its deepestpoint the unconformity is more than 30,000 ft(9,100 m) below sea level. Faulted strata at this depth mean thatthe Rough Creek Fault System penetrates...

The northern part of the map area and large adjacent regions havebeen severely shaken by one or more moderate to large prehistoricearthquakes. The evidence of these takes the form ofpaleoliquefaction features, including shaking-induced sandblows anddikes that fed them.Over several summer field seasons from 1990 through 1994,several workers searched ditches and river banks for evidenceof liquefaction. They found numerous dikes and sandblows.This database includes the locations and descriptions of dikes theyobserved and measured.The most widespread paleoliquefaction is attributed to amid-Holocene earthquake near what is now Vicennes, IN, with anestimated moment- magnitude of about 7.5. Stratigraphic,geomorphological,...

This cover consists of location and size information for historicaland recent earthquakes that caused Modified Mercalli Intensity(MMI) VI (6) or higher in the map area. There were 26 earthquakesthat caused that level of damage. The most reknown are thefour earthquakes in the 1811- 1812 sequence; two on Dec 16,1811, and one each on Jan 23, 1812, and Feb 7, 1812. Theircalculated Moment Magnitudes were 8.1, 7.2, 7.8, and 8.0,respectively. The most recent damaging earthquake was on June 10,1987 near Olney, Illinois. It had a Moment Magnitude of 5.2.

Over several summer field seasons from 1990 through 1994,several workers searched ditches and river banks for evidence ofliquefaction. They found numerous banks with shaking-induced,pre-historic, earthquake induced sandblows and thedikes that fed them. This database shows where they searched.

This cover contains station locations of the New Madrid SeismicNetwork within the study boundary. The network is a cooperativeproject of Saint Louis University and Memphis State University.Operation of the network has been continuous since June 1975, butoperators have changed the network configuration throughout thattime period. The start and stop dates in the point attribute fileare not complete, but are included because they are useful for someof the stations.

NOTE: Location of one point, near -88.65, 38.95, was incorrectwhen Sheet A was published. The location is .5 degree south, andis corrected in this dataset.This cover contains locations of places where greatest horizontalcompressive stress (S(Hmax)) orientations havebeen determined either by observation of well-bore breakouts or wherefocal mechanism solutions have been determined from earthquakes.Well-bore breakouts are observed from 0 to 1.4 km, whereas earthquakesgenerally occur deeper. The earthquake focal mechanismsshow both reverse and strike-slip faulting. Overall the stressindicators show easterly trending S(Hmax).

This cover contains wells identified by Dart as having useful informationfor defining the Paleozoic basement in the New Madrid region. Some wells hadborehole breakout data that were useful for interpreting the regional stressfield. These locations are included in the cover "stress" and identifiedwith type 'b'. Data from other wells was more useful for controlling depthto the basement, or providing information useful for determining the riftinghistory of the Rough Creek Graben and Reelfoot rift, or coeval riftingelsewhere in the map area. These and other wells are included in cover"cwell".

Lines in this cover show lineaments or boundaries of largelineaments interpreted from gravity and magnetic data. Theselineaments are thought to reflect structures in the crust that may berelated to earthquake generation or control of earthquake location.The broad Paducah gravity lineament trends southeast across the SW cornerof the map area. Hildenbrand and others (1996) have interpreted that thelineament represents numerous upper-crustal mafic intrustions.Within and west of the map area, small earthquakes are aligned withthe NE edge of the lineament and their abundance decreases abruptlyNE across the edge.The Commerce geophysical lineament trends NE across the map area.Langenheim and Hildenbrand (1997) attribute...

The structure of and depth to the floor of the Mississippi Valley andRough Creel Grabens and surrounding regionswere interpreted from aeromagnetic data.This cover contains the depth contours for the region within thisstudy area and was clipped from the larger cover.This cover was not plotted in the Wabash Valley map series, but isincluded for those users who are interested in comparing the depthto basement from geologic data (bcontours and bfaults) to the depthto magnetic rocks (usually basement) from geophysical data.Depth units in this cover arekilometers below sea level, whereas depth units in bcontours are inthousands of feet below sea level.
