Merapi is a strato-volcano located in Central Java, Indonesia, about 30 km north of Yogyakarta city which has more than one million inhabitants (Figure 1, Figure 2). It is part of the volcanic front of the Sunda-Banda magmatic arc produced by subduction of the Australian plate under the Eurasian plate.
