2010 eruption, free air anomaly, mount merapi, topographic, volcano


Mount Merapi eruption in 2010 was one type of eruption with large scale during the last 100 years. Eruptions that was occurred resulting topographic changes in the peak of Mount Merapi, and the possibility of changing the subsurface structure. The research was part of a large study that has been conducted to assess the subsurface changes of pre-and post-eruption of Mount Merapi in 2010. The study discussed observations of free air anomalies pre and after the 2010 eruption. There were grouped into three periods. Processing of air anomalies was free to use using the 2nd orde calculation method. The results obtained were the changes in the contours of the FAA Mount Merapi in 1988, 1998, and 2011 as a result of topographic changes that occurred in the peak area and the alleged dynamics of the surface. The dynamics at Mount Merapi in the 1988 to 2011 period occurred in the northwest, southeast, east, and northeast of the study area and southeast of the peak of Mount Merapi.
