In May of 1960, the Philippines had a terrible tsunami.  A big killer wave hit Chile, Hawaii, Japan and then the Philippines and it cause a huge loss of life, and great destruction to land, the shoreline and the entire infrastructure of the area. Then in August of 1976, the southern part of the Philippines had an 8.0 earthquake.  It caused another tsunami and over 10,000 people were killed by it.  Then in 2004, the earthquake  underwater in the Indian Ocean caused the biggest and deadliest tsunami  that there had ever been, and it hit many large land masses in that area, killed hundreds of thousands of people, and ruined the tourist business that many countries count on for economic stability.  All of these tsunamis happened with little or no warning for the people who live in that region.
