How tsunamis occur. As one plate subducts below another (moves underneath)‚ pressure builds for many years resulting in a section of the mega-thrust giving away. As this section gives away‚ it ruptures the ocean floor‚ resulting in a massive displacement of water‚ causing a tsunami. Tsunamis are barely felt as a ripple on the ocean’s surface‚ but as the waves reach land‚ they increase in size as the water becomes shallower.

Japan Tsunami and Earthquake Sion Hau 7D 31/07/11 An earthquake occurred in Sendai‚ Japan on the 11th of March in 2011; this earthquake also resulted in a tsunami. The earthquake measured at magnitude 8.9-9.0 on the Richter scale‚ the scale is measured in powers of ten (e.g. magnitude 2.0 is ten times more than magnitude 1.0).

23-foot tsunami in the country’s north. The giant waves deluged cities and rural areas alike‚ sweeping away cars‚ homes‚ buildings‚ a train‚ and boats‚ leaving a path of death and devastation in its wake. Video footage showed cars racing away from surging waves. The United States Geological Survey reported the earthquake and on Monday revised its magnitude from 8.9 to 9.0‚ which is the largest in Japan’s history. The earthquake struck about 230 miles northeast of Tokyo. The Pacific Tsunami Warning

Tornadoes and tsunamis both are two natural disasters. Both Tsunamis and tornadoes are formed by nature but‚ they form differently and have different destruction levels. Tornadoes and Tsunamis are formed by natural weather. Not normal weather though‚ they are formed by other nature freaks and non-normal weather. They also create massive destruction in different ways. They are both very interesting topics on the way they form and their destruction. Tornadoes and Tsunamis are both natural disasters
