Relative earthquake hazard maps compare the expected violence of earthquake ground shaking and likely damage over a map area produced by a generic earthquake outside of the mapped region. Relative earthquake hazard maps are usually a combination of several different earthquake risks added together. For example, the Oregon Department of Geology and Mineral Industries (DOGAMI) constructed relative earthquake hazard maps for regions in Oregon by combining slope instability (landslide), amplification of ground shaking by weak near-surface geology, and liquefaction potential into one map. Areas of particularly high earthquake risk are mapped as “red zones” often because of high liquefaction potential near waterways (rivers and lakes) or because of large thickness of weak near-surface geologic layers such as unconsolidated sediments. This classroom activity combines three related activities into one: a slope instability demonstration; a ground amplification demonstration; and a liquefaction experiment.
