The sounding points in this cover show where data was collected that was then modelled for deep structure (see reference). Purpose: The data was generated to help in understanding the seismotectonic hazards in the vicinity of the lower Wabash Valley. This data complements similar data collected in the vicinity of New Madrid, MO (US Geological Survey Open-File Report 95-0574, available via ftp at ) Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1995 Ending_Date: 1996 Currentness_Reference: all soundings and modelling lines are included Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -91.94407654 East_Bounding_Coordinate: -86.77889252 North_Bounding_Coordinate: 37.92121124 South_Bounding_Coordinate: 34.66292953 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: magnetotelluric modelling Place: Place_Keyword_Thesaurus: None Place_Keyword: Wabash Valley Access_Constraints: none Use_Constraints: none Point_of_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Susan Rhea Contact_Organization: US Geological Survey Contact_Position: Geophysicist Contact_Address: Address_Type: mailing address Address: MS966, Box 25046, Federal Center City: Denver State_or_Province: CO Postal_Code: 80225 Country: USA Contact_Voice_Telephone: 303-273-8639 Contact_Facsimile_Telephone: 303-273-8600 Contact_Electronic_Mail_Address: rhea@usgs.gov Contact_Instructions: email is the best way to make contact Data_Set_Credit: Rhea Native_Data_Set_Environment: SunOS, 5.5.1, sun4u UNIX, ARC/INFO version 7.1.1 Cross_Reference: Citation_Information: Originator: Wheeler, R.L., Diehl, S.F., Rhea, Susan, Sargent, M.L., Bear, G.W.
