About 280 kilometers of multichannel (common-depth-point) seismic reflection profiles were obtained in the central Mississippi River Valley by Geophysical Service Inc. and Western Geophysical Company under contracts with the U.S. Geological Survey. The specific area of the profiles is southeastern Missouri, northeastern Arkansas, and northwestern Tennessee. Geologically, the area is located in the northern part of the Mississippi Embayment.
Fault Source parameters used as input to 2002 National Seismic Hazard Map.

Introduction This data release is a compilation of known landslides, debris flows, lahars, and outburst floods that generated seismic signals observable on existing seismic networks. The data release includes basic information about each event such as location, volume, area, and runout distances as well as information about seismic detections and the location of seismic data, photos, maps, GIS files, and links to papers, websites, and media reports about the event. Not all record types exist for each event, and the quality of the information varies from event to event. While the SQLite3 database (lsseis.db) is the native format of this database and preserves its relational structure, for the convenience of users,...
