tsunami, amplification of wave amplitudes, collapse of wave crestsAbstract
This article considers the generation of a tectonic tsunami and explains two important phenomena that occur when waves approach shore. One of the phenomena is the compression of the waves, an increase in their amplitudes and a decrease in their speed when a tsunami enters shallow waters near the coast. As a result, the potential energy of tsunami waves and their destructive power increase. Another phenomenon that is discussed is the collapse of the wave crests when they reach the shore. This is a complex physical process that is characteristic of many sea and ocean waves.
