     This report illustrates, by means of a computer animation, how an
earthquake occurs and what types of damage may result*. The report is
intended to help students and others visualize what causes earthquake
shaking and some of the possible results of the shaking. By studying the
animation and the paper model, students will come to understand that
earthquakes result from faulting in the Earth and that the potential
consequences of earthquakes are numerous and serious.  Included in the
diskette version of this report are the templates for making a paper model,
instructions for assembly, educators' guide, and animations describing the
effects of the earthquake, including the collapse of structures, fire, and a
tsunami. The paper version of this report includes everthing except the
animations.
