Tsunami alerts were triggered up and down the Oregon Coast this morning, following a deadly 8.9 magnitude earthquake in Japan.  Reverse 911 calls and emergency sirens alerted Oregon coastal residents to potentially dangerous tsunami waves created by the distant quake, and the National Weather Service has issued a tsunami advisory.  Oregon Sea Grant features a short film on tsunami preparedness: “Reaching Higher Ground: The 3 Things You Need to Know” (3:09).
