Many people acted heroically in the aftermath of Hurricane Katrina. The Coast Guard, for instance, rescued some 34,000 people in New Orleans alone, and many ordinary citizens commandeered boats, offered food and shelter, and did whatever else they could to help their neighbors.
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.

If you mean if it is possible to predict the behaviour of a tsunami, then the answer is yes. Tsunami follow set equations of wave behaviour, and therefore elements such as speed, height, wave period etc can be found and modelled. 8 people found this useful.assive earthquakes is a sign of a tsunami, if your living on the coastline, move to a higher ground regardless of how massive the quake you felt was.
