North Coast Journal March 20, 2008 : GARLICK'S NOTEBOOK: TITLE: "Understanding the nature of tsunamis could save your life. They are usually caused by large earthquakes, coastal or submarine. You could expect timely warning of a tsunami generated thousands of miles away, but if our local Cascadia Megathrust is the culprit, the violent shaking would be your cue to head for the highest ground reachable within a few minutes."
