All 12 Earthquake Answers fault models in one download, with the Instructor Guide. Each model plays the full earthquake cycle in 3D: strain builds on a locked fault, the rupture starts at the focus and spreads, seismic waves shake the ground, and roads, railroads, aqueducts and buildings are offset or damaged.

Included: right- and left-lateral strike-slip, normal, reverse, thrust, blind thrust, oblique-normal, oblique-reverse, and four step-overs (pull-apart basins and pop-ups). The Instructor Guide has learning outcomes, model-by-model teaching notes, a lab sequence, a student worksheet with answer key, and common misconceptions.

Works offline in any current browser on Windows, Mac or Chromebook, with no installs. Created by Robert Leeper, Professor of Geology and former USGS geologist.
