Learning Task 5: Read the text and complete the table below. Then, convert the details of the given text into a diagram using appropriate graphic organizer. Do this in your notebook. Sie die Tsunami is a series of waves that are produced by the sudden movement of the seabed---earthquakes, volcanic eruptions, underwater landslide or even an asteroid. But frequently, they are set off by earthquakes occurring at a depth of less than 50 meters measuring at least 6.5 in magnitude. At a magnitude of eight (8), a tsunami can be devastating. The shifts of the ocean floor caused water to be folded, lowering the sea level and deforming the surface of the ocean. Seismic waves are produced which in turn trigger another series of waves in deep water far from the epicenter of the earthquake. The tsunami reaches a few thousand centimeters, but its height increases as the bottom of the ocean floor rises. In extreme cases, the waves take on speed of 500 to 800 kilometers per hour when the water is very deep, decreasing in speed to about 20 or 30 kilometers per hour as they approach the coast. The waves can reach heights of up to 30 meters, breaking one after the other at intervals of 10 to 40 minutes sweeping away everything in their path. Tsunami, which is a Japanese word for harbour wave, occurs mainly in regions of strong tectonic activity. Source: https://www youtube.com/watch?v=d564RTZ6Wig​
