  1. Tsunamis Human responses to the changing Earth By Hassan and Muna

  2. Here is a video of how a tsunami happens and what effect happens!!!!

  3. Introduction Tsunami means harbor waves in Japanese. Some people call Tsunamis Tidal waves but tides do no create waves. Most waves come from wind moving over water. Tsunami waves come from deep down in the ocean. Tsunamis start when a huge volume of water is quickly shifted.

  4. What causes a Tsunami to happen? Tsunamis are caused by an underwater Earthquake, a volcanic eruption, a submarine, an underwater rock slide, or more rarely by an asteroid or meteorite crashing into the water from space. Most Tsunamis are caused by underwater Earthquakes, but not all underwater Earthquakes cause Tsunamis – an Earthquake has to be over about magnitude 6.75 on the richer scale for it to cause a Tsunami. About 90% of all Tsunamis occur in the pacific ocean.

  5. How do Tsunamis change the Earth and continue to change the Earth? Tsunamis change the Earth by destroying houses, roads, apartments, hotels and schools. Tsunamis change the Earth by destroying valuable things and changing the image of things by destroying them. Tsunamis continue to change the Earth by destroying more useful things such as money and shelter. Technology is useful because a phone is technology and you might need to call for help during a Tsunami.

  6. Human responses to Tsunamis Humans have a warning system to warn people. Humans say, “ In case of Tsunamis go to high ground or in land.

  7. This is a video of the 2004 Tsunami!!!!

Tsunamis are often barely visible when they are in the deep sea. Five days after the 2004 Tsunami, a woman named Malawati was found alive clinging to a palm tree. She was a 100m out to sea.
