What is a Tsunami?
According to the UN, the word "tsunami" has Japanese origins, it comprises the Japanese words "tsu" (meaning harbour) and "nami" (meaning wave). Hence, a tsunami is a series of enormous waves created by an underwater disturbance which is usually associated with earthquakes occurring below or near the ocean. The Tsunami waves often look like walls of water and can attack the shoreline and be dangerous for hours. The waves can be recurring every 5 to 60 minutes.
While the first wave may not be the largest, it is the 2nd, 3rd, 4th or waves that come even later are the bigger. After one wave inundates, or floods inland, it recedes seaward and goes back often as far as a person can see, hence the seafloor becomes exposed. The next wave then rushes ashore within minutes and carries with it much floating debris. destroyed by previous waves.
