The Circum-Pacific Belt, also known as the Ring of Fire, is a horseshoe shaped path along the Pacific Ocean where tectonic plate movement are great; the area is surrounded by subduction zones, where a plate is pushed down under by another plate. These movements and subduction zones causes the Ring of Fire to high volcanic activities and common earthquakes. Over 90% of earthquakes occur and 75% of earth's volcanoes are located in the Ring of Fire. Volcanic eruption underwater and earthquakes can also trigger other causes of tsunami, thus increasing the likelihood of the disaster occurring and the intensity of it.
