National Level Exercises: History, Authorities, and Congressional Considerations [July 15, 2021] [open pdf - 468KB]
From the Document: "Every two years, the Federal Emergency Management Agency (FEMA) conducts a National Level Exercise (NLE) to evaluate the nation's progress towards preparedness for catastrophic events. These exercises have multiple components, and culminate in a large, full-scale exercise with thousands of participants from multiple federal agencies, state, local, tribal, and territorial (SLTT) governments, industry partners, and nongovernmental organizations. The next NLE, scheduled for 2022, is to test the nation's ability to respond to a simulated earthquake along the Cascadia Subduction Zone in the Pacific Northwest, as well as subsequent aftershocks, tsunamis, and a Spill of National Significance."
