Seismic Reflection and Refraction Methods

Science Center Objects

Seismic reflection and refraction methods are major tools in natural hazard assessments. Useful tools were developed to aid in processing and modeling of these data.

RayGUI is a Graphical User Interface (GUI) that allows you to interactively edit velocity models and ray-tracing parameters. Ray-tracing is performed by invoking rayinvr from the GUI. After ray-tracing is completed, RayGUI displays observed and modeled traveltimes, and optionally, rays. RayGUI is written in JAVA, rayinvr in FORTRAN77, and auxiliary programs in FORTRAN 77 and ANSI-C.
