SeismoGraf, GPSgraf, and SeismoView Software
These three programs operate a Macintosh-based digital seismograph, and offer basic display and analysis of digital seismograms.
Epilocator is a stand-alone hypercard-based application that will locate the epicenter of an earthquake from arrival time data and calculate the magnitude. It also is a self-contained data base that allows the user to paste in additional pictures and text.
