Watch this video - OPB's "Unprepared"

This 1 hour Documentary is part of an integrated radio, TV and online effort that examines our region's vulnerability to a mega-quake. The Pacific Northwest has seen earthquakes before. But Cascadia subduction zone earthquakes are completely different—and will trigger massive destruction from British Columbia to California and produce tsunamis that can wipe entire towns off the map. The geologic record reveals that they strike every 300 to 500 years. The last one was in 1700. Can we prepare? How? And what lessons can we learn from earthquakes elsewhere?
