BA major offshore fault zone capable of producing magnitude 8–9 earthquakes and tsunamis that could devastate Oregon coastal and valley areas — a material risk factor for property owners✓ Correct

DA geographic feature affecting only government-owned land

Explanation

The Cascadia Subduction Zone (CSZ) is the boundary between the Juan de Fuca and North American tectonic plates located 50–100 miles off the Oregon coast. It is capable of producing megathrust earthquakes of magnitude 8.0–9.2 and associated tsunamis. Oregon real estate agents, especially for coastal and low-lying valley properties, must understand and disclose this significant natural hazard risk.
