Name: Fault Trenches

Display Field: TRENCH_NAME

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Geologists excavate trenches across faults to determine more detailed information about earthquake history on the fault. Information from this type of study includes the direction of fault movement, the number and timing of earthquakes, and the recurrence interval. Finding faults and knowing how often they rupture is one of the most important tasks needed to fully characterize earthquake hazards. Such information moves society towards a full enough understanding of the frequency of earthquakes in a given region to make earthquake forecasting possible.
