Subduction zone earthquakes are the largest and most destructive on earth. In 2004 a 9.1 megaquake hit Sumatra off the coast of Indonesia, unleashing a massive tsunami and killing 227,898 people. And in 2011, the Tohoku earthquake struck Japan, killing around 20,000 and triggering the infamous Fukushima nuclear disaster. In the Pacific northwest lurks the Cascadia Subduction Zone, which has been dormant for centuries and is overdue for its next “big one.” In this episode we’re going to tell you what experts think is the best way to survive this inevitable disaster.
