Focus for this week: Tsunamis
The word Tsunami or ‘harbour-wave’ comes from the Japanese word ‘tsu’, which means harbour and ‘nami’ which means wave. They are commonly known as ‘killer waves’. Sounds a bit scary doesn’t it? Well you definitely wouldn’t want to be around when a tsunami happens. A Tsunami is a large amount of ocean waves, which get stronger and more powerful as they move along. They are caused by pressure in the atmosphere, a volcanic explosion, an underwater earthquake or landslide or even a meteor hitting the ocean.
