Interactive Graphics Package for the MEGATEK 7250 Terminal of the Seismic Analysis Station at the Centre for Seismic Studies.

Abstract

This document describes five software modules developed for the maps color graphics terminal (MEGATEK 7250) of the Seismic Analysis Station of the Centre for Seismic Studies. These modules permit interactive graphic analysis of: (1) Signal and noise windows selected from a seismogram for purposes of optimal interactive signal-to-noise filtering of raw data; (2) Earthquake fault plane solutions; (3) Three-dimensional representations of geographic, tectonic and geophysical information on the surface of the globe; (4) Two-dimensional maps in any of eleven different projections; and (5) Seismic rays and associated parameters such as travel-times in a spherically symmetric earth model. Examples of screen displays are provided in this report together with a description of the capabilities offered by each module.
