Abstract

Indonesia became an area passed by the Pacific Ring of Fire which was the meeting place of two active tectonic plates, which caused Indonesia to have many volcanoes. One of them is Mount Merapi. Mount Merapi is located on the border between Central Java and the Special Region of Yogyakarta, which is located at 7o32.5'LS and 110o26.5'W with an altitude of 2,978 diameters of 28 km, an area of 300-400 km2 and a volume of 150 km3 . Merapi is a stratovolcano-type volcano with a cone�shaped andesite-basaltic type of magma. Seismic method aims to find out more the characteristics of the volcano. One indicator to see the early possibility of eruption is the occurrence of volcanic type earthquake (VTA) which is then accompanied by the emergence of shallow volcanic type earthquake (VTB). Volcanic earthquake data of Mount Merapi which can be as many as 5 volcanic earthquake events in the period of August 18, 2017 to August 31, 2017. Hypocenter points obtained have varying depth at different times. The accuracy of hyposenter points can be influenced by the picking results of the arrival time of the primary wave. We can conclude that in the period August 18, 2017 to August 31, 2017 is a type of deep volcanic earthquake.
