Problem: In the Journal of Earthquake Engineering, a team of civil and environmental engineers studied the ground motion characteristics of 15 earthquakes that occurred around the world between 1940 and 1995. Three variables measured on each earthquake were the type of ground motion (short, long, or forward directive), earthquake magnitude (Richter scale), and peak ground acceleration (feet per second). One of the goals of the study was to estimate the inelastic spectra of any ground motion cycle.
