Doesn't make sense
Along the ring of fire we have major faults and some dormant volcanoes that can cause far more devastation than tornadoes.
Along the western Washington Coast and into Puget Sound we have the risk of a tsunami similar in scope to the Indonesian tsunami. Such a tsunami would wipe out whole towns and cities along the coast. Some of these towns are built on low lying peninsulas that have limited escape routes that thousands of tourists and locals would crowd onto but with only 20 minutes of advanced warning. And this assumes the path isn't blocked by downed power lines.. The egress would be swept over by a tsunami flow. In fact, we're told by the Feds if and when 'the big one' hits, we along the coast are on our own for as much as 10 days while they focus on Seattle and the I-5 corridor.
