"Tsunami" is the Visualization Lab's latest production for the NOAA Science on a Sphere exhibit, viewable at over 40 locations worldwide. Tsunami takes a look back at the devastating 2004 Indonesia tsunami: what happened, what was learned, and what NOAA and its international partners have done since then to improve the safety of coastal populations. "Tsunami" also examines what will happen if and when a tsunami occurs off the coast of the United States near Oregon. How will alerts go out? How will you know a tsunami is coming? Watch "Tsunami" and learn the signs. All coasts are vulnerable to tsunamis. Be prepared. Note: File contains video and audio content.
