Also, the island reported devastating economic loss in millions of dollars due to hotels, housing, public utilities, and fishing damages. In recent years, the term "tidal wave" has fallen out of favour, especially in the scientific community, because the causes of tsunamis have nothing to do with those of tideswhich are produced by the gravitational pull of the moon and sun rather than the displacement of water.
It took a relatively long time to reach Struisbaai at the southernmost point of Africa, probably because of 2004 tsunami introduction broad continental shelf off South Africa and because the tsunami would have followed the South African coast from east to west.

This was followed by a large withdrawal of the sea before the second and third waves hit. People running from the shore shouted that the sea was rising. It was caused by subduction with an epicentre off the west coast of the Indonesian island of Sumatra.
A major aftershock magnitude 7. Thus people lived dangerously close to the water and often on ships that would not be seaworthy in areas where tropical cyclones are common. This is the formula used for calculating the velocity of shallow-water waves. The relatively tiny wavelengths mean that wind waves behave like deep-water waves in open ocean, transitioning into shallow-water waves near the shore.
Tsunamis and tides both produce waves of water that move inland, but in the case of a tsunami, the inland movement of water may be much greater, giving the impression of an incredibly high and forceful tide.
