Title: Analog Model and Synthetic Seismogram Studies of Long Range Previous HitRefractionNext Hit Method: ABSTRACT

Author(s): Stanley J. Laster, Richard Schell, Milo M. Backus

Article Type: Meeting abstract

Abstract:

Previous HitRefractionNext Hit mapping of a simple anticline in a high velocity halfspace overlain by low velocity overburden in an analogue model illustrates the conventional Previous HitrefractionNext Hit method and the behavior of Previous HitrefractionNext Hit traveltime and amplitude. In addition to first arrivals, the later arrivals on the seismogram, the "multiple Previous HitrefractionsNext Hit," which constitute the PL mode in the reflection noise problem and long period earthquake seismograms, were studied in detail. In the absence of structure, the behavior of the later Previous HitrefractionsNext Hit on the model agrees with the predicted behavior from exact synthetic Previous HitrefractionTop seismograms obtained from the computer application of Cagniard's method to a layered half-space. Over the structure, the arrival time and amplitude behavior of the later a rivals is simply diagnostic of the structure.
