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.

Who Studies tsunamis. Many people are often mistaken that Tsunamis are mainly caused by earthquakes, because of this, many scientists that study earthquakes, like Geologists and Seismologists, help with the study of Tsunamis. Scientists that mainly study Tsunamis are hydrologists, and oceanographers. And they also work on how to predict them. Predicting a tsunami cannot always be precise, but what scientists do know, is that a Tsunami is most likely to occur after an earthquake.
