Tidal waves, or tides, are a predictable, com-mon occurrence along coastal communities, generated by forces beyond Earthâthe gravitational pull of the sun and moon. However, tsunamis are not predictable. They are often generated by earth-quakes, volcanic activity, and slope failure.idal waves, or tides, are a predictable, com-mon occurrence along coastal communities, generated by forces beyond Earthâthe gravitational pull of the sun and moon.

List of Tsunami's Tsunami's are caused by the abnormal movement of the earth when the axis shifts. Associated quakes are usually a byproduct of the shift. Put 4 of water in an aquarium and slide it sideways to see how tsunami waves are created by movement of the planet.hey don't mention Tsunami's where there were few witnesses. Rogue waves are also unreported Tsunami's. Each are evidence of abnormal shifts of the earth & axis. The largest shifts occurred in 2004, 2006, 2011, 2013 & 2014.
