The KGS seismic-reflection program addresses engineering and subsidence issues in Kansas and elsewhere. Using seismic reflection techniques, KGS researchers create a vibration—with an explosion or specially equipped truck—that sends seismic (sound) waves into the ground. The rebounding energy, which reflects off different rocks in different ways, is then measured to produce images of underground rock layers.
The U.S. Army Corps of Engineers has awarded the KGS a grant to advance the research and development of an automated subterrain anomaly-detection system using active seismic-imaging (ASI) technologies to be used for clandestine tunnel detection, classification, and evaluation. The KGS also received Corps funding for a study of unconsolidated sediments on the Yuma Proving Grounds in Arizona; U.S. Department of Interior and Bureau of Reclamation funding for a seismic study at A.V. Watkins Dam in Utah; and U.S. Geological Survey funding to study geophysical-methods development for subsurface characterization of near-surface settings.
