Tsunamis
I’m gonna talk about tsunamis. A tsunami is often misnamed by tidal wave but it’s completely false. A tsunami is usually series of eight or nines waves. For example in our beaches, the waves are only about one, two metres high but in tsunamis they grow to heights as high as 85 metres. The most causes of tsunamis are seaquakes and earthquakes, in regions like Sri Lanka, Malaisia and Bangladesh in the Pacific islands.
