A huge dress rehearsal for regional earthquake disaster relief was supposed to happen next week until the ongoing pandemic forced it to be shrunk and moved online. The original Cascadia Rising 2022 exercise would have involved more than 22,000 participants – chiefly U.S. soldiers, sailors and airmen as well as state, local and tribal emergency planners. Some smaller drills are going ahead this weekend and next featuring civilian volunteers who will demonstrate unusual ways aid may get to Pacific Northwest earthquake survivors.
