The energy of a tsunami, which is the total amount of energy it carries, is directly proportional to the square of its amplitude (height of the wave) and the square of its frequency (number of waves per unit time). So, if the amplitude and frequency of a tsunami are increased, the energy it carries will increase significantly, since the energy is proportional to the square of both the amplitude and frequency. Therefore, an increase in either or both of these parameters can result in a more destructive tsunami, with greater potential for damage and loss of life.
