The shock occurred on the southern coast of Java near the Indonesian city of Yogyakarta, and caused a disproportionate number of casualties, with more than 5,700 deaths and 37,000 injuries, and financial losses of (Rp 29.1 Trillion ($3.1B)). The eruption of Mount Merapi, a stratovolcano that was entering a period of unrest, was originally thought to have a connection with the earthquake. With a lack of instruments in the area, the shock was initially attributed with the Opak Fault that lies to the east of the affected areas, but later InSAR analysis revealed that another previously unknown fracture was responsible for the sequence of shocks. ==Tectonic setting== The islands of Indonesia constitute an island arc that is one of the world's most seismically active regions, with high velocity (up to per year) plate movement at the Sunda Trench, and considerable volcanic activity throughout. The south central portion of the island of Java (one of the five largest in the Indonesian archipelago) had been affected by an eruption of Mount Merapi that began prior to the May 27 earthquake, but the Special Region of Yogyakarta has experienced numerous other eruptions, earthquakes, and tsunamis, including the Pangandaran earthquake and tsunami that occurred just two months later. Java lies on the Sunda Shelf (and the Sunda microplate) to the north of the Sunda Trench, which is a convergent plate boundary where the Indo-Australian Plate is being subducted under the Eurasian Plate. The subduction zone is characterized by frequent earthquakes and a large number of active volcanoes that influence the regional geography, and due to direct or indirect stress transfer, the offshore plate movement has affected the various onshore faults that are closer to the Special Region of Yogyakarta. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2006 Yogyakarta earthquake」の詳細全文を読む スポンサード リンク
