This document outlines a term paper on assessing fault activity from a mineralogical perspective. It discusses electron paramagnetic resonance (EPR) dating of faults. EPR dating measures radiation-induced paramagnetic centers in minerals to determine the accumulated radiation dose over time. This can date fault movements by dating minerals crushed during faulting or precipitated in fault zones. The document presents a case study of the Eupchon Fault in South Korea, where EPR dating of fault rocks indicates reactivation approximately 2000, 1300, 900-1100, 700-800, and 500-600 thousand years ago, showing it is potentially active with seismic hazards.
