The Total Seismic Environment*
Lecture by John Wardel – 1982


This movie is a continuation of the “Introduction to the Seismic Reflection Method of Prospecting” presented in the September 2020 issue of the GSH journal.

In the previous lecture we looked at how seismic energy travels through the earth, different kinds of wave motion and how seismic energy is reflected from interfaces between different rocks. We also looked at the basic elements of the system used to record these reflections and how reflections are displayed to give a picture of the rocks’ structures in the earth.

In this lecture we look at different kinds of reflections and events that occur, and how these appear on the recorded seismic traces. The events analyzed include: Primary reflections, Multiple Reflections, Reverberations and Ghosts.
