Gravity and magnetic signatures result from deep structure, such as might be at hypocentral depths of earthquakes. We show only the lines for which interpretations or models are publically available. In gravmag_all, extent of the lines outside the study boundary is retained; in gravmag the lines have been clipped to the study boundary. 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: 1982 Ending_Date: 1996 Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -89 East_Bounding_Coordinate: -87 North_Bounding_Coordinate: 39 South_Bounding_Coordinate: 36.5 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: gravity and magnetic lines 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 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.

Completeness_Report: Since our study focused on large structures that might penetrate to hypocentral depths, we excluded shallow geophysical surveys aimed at solving surficial problems (engineering, landfill, or mining problems.) We show only lines for which interpretations have been or will soon be published, including lines from theses and dissertations. We ignore most proprietary lines. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Many of the lines are portrayed on small-scale figures in reports. We attempted to generate digital coordinates of the lines from these reports, but the accuracy of location is poor. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 10 km Horizontal_Positional_Accuracy_Explanation: Resolution varies because scale of source media varied. Most sources were figures from published reports. Some sources were tables listing location of one endpoint, aximuth and length of line.

Decimal degree coordinates for Hildenbrand's lines were sent via email and converted to arcinfo. Lines were labeled for reference on the paper map, and annotation was added. For gravmag, the data was clipped to the project boundary.
