Mount Unzen Dake is located in Kyushu Japan. The last time Unzen erupted was 1996. Unzen is 1,500 metres high or 4,921 ft.The U.S.D.P is the Unzen Scientific Drilling Project.In 1999, an ambitious project began at Mount Unzen to drill deep inside the volcano and sample magma in the 1990–1995 eruption conduit. The project hoped to shed light on some fundamental questions in volcanology, such as why magma repeatedly travels in the same conduits despite the solidification of magma in them at the end of each eruption, and how it can lose enough gas on its ascent to erupt effusively rather than explosively.
