Science points to a large 8.0-9.0 magnitude Cascadia Subduction Zone (CSZ) earthquake ripping across the 800-mile CSZ fault line once every 200 to 500 years. The last major earthquake and tsunami occurred in 1700, which means authorities need to prepare now for a potential catastrophic event that could endanger eight million lives.
More than 50 counties, cities, tribal nations, state and federal agencies, private sector businesses, and nongovernmental organizations across Washington, Oregon and Idaho and one Canadian province, participated in the four-day Cascadia Rising 2016 Exercise. To develop a coordinated response to a CSZ event, WSP provided exercise planning, facilitation and documentation services over a four-month period to the Oregon Office of Emergency Management (OEM) and its multi-state partners, all in varying capacity and at different stages in the planning process.
