A series of ground-penetrating radar (GPR) lines were acquired on a proposed multistory building site in Fayetteville, Arkansas, because engineering work implied the existence of a shallow fault. Building a heavy structure in the vicinity of this fault would involve risk due to differential settlement, solution cavities, and fault reactivation. In this case, the new radar surveys, combined with pre-existing borehole data and regional geological knowledge, verified and mapped the fault.
