Tsunami 101

TSU - HARBOR;  NAMI - WAVE = TSUMANI...    Weather Expert, and fellow Rotarian, John Lindsey gave us an abbreviated version of harbor wave action and the impacts they could have on land.  He explained that there are 3 types of ocean waves - 1) wind generated waves; 2) tidal cycle waves; and, 3) tsunamis (or seismic sea waves).   The wave length (measured crest to crest) tells us which kind of wave we are seeing.  In a worst case scenario, seismic action creates the swells, then based on the wave length - the longer the wave length, the more the wave continues to surge - you can determine the height of a tsunami and very possibly what damage it has the potential to do.  Well, at least John can do that...   us??  not so much...
