A set of four, public-domain, educational computer programs have been developed that assist a student in learning about earthquakes. These programs are:
Seismic/Eruption: shows where and when earthquakes and volcanic eruptions occur in accelerated time on maps of various regions. A set of teaching modules are on the Web for Seismic/Eruption.
Seismic Waves: provides an animation of wave propagation through the interior of the Earth. Synchronized with the waves are actual seismograms displayed in one window and, in another window, the P, PP, S, SS, and surface waves at any moment in time.
AmaSeis: a program for recording data from a seismometer. It is designed primarily for use with the AS-1 seismometer which has been provided to a number of schools by IRIS (Incorporated Research Institutions for Seismology). An event can be extracted from the helicorder display and then filtered and saved.
EqLocate: assists a user in locating an earthquake by trial and error using only P waves on seismograms from several stations. The P arrivals and a trial epicenter are selected by the user. The error is shown graphically, allowing the user to refine the location.
The programs run under Windows®. They are available at http://www.geol.binghamton.edu/faculty/jones.
Note: These programs depend on color to convey much of the meaning, whereas the figures in this paper are reproduced in black and white. Also, the programs are very dynamic and interactive and appear not unlike video games. Therefore, in order to fully appreciate the programs, it is recommended that the reader fetch the programs and run them.
Seismic/Eruption shows where and when earthquakes and volcanic eruptions occur in accelerated time on maps of various regions. The program has a database of earthquakes and a database of volcanic eruptions from 1960 to the present. The earthquake database can be updated to …
