Abstract
Abstract Almost all of the Indonesian territories are high potential of geologic disaster, such as earthquake, tsunami, volcanic eruptions, and landslides, because the country belongs to tectonically active. There are three big lithosperic plates interact one another influencing the tectonic setting of Indonesia. The plates are Indo-Audtralia Plate, Eurasia Plate and Pasific Plate. Indo-Australia Plate moves relatively northward by about 9 cm/year rate, Eurasia Plate creeps southeastward with approximately 7 cm/year speed, and Pacific Plate moves to the west with around 11 cm/year velocity. In the meeting line of the plates, about 300 km to the south of Indonesian Islands, there is the subduction zone that become to be places of where earthquake focuses are generated. Earthquake from submarine source with more than 6.5 magnitude is potencial to generate tsunami. Areas situated along the south coast of Indonesia islands are vulnerable to tsunami, because directly facing the boundary lines between Eurasia Plate and Indo-Australia Plate. This study verified that there is positive correlation between coastal line geometry and the tsunami impact, based on fractal analysis. The case study is Maumere, Flores island, East Nusa Tenggara, Indonesia. Result of the study is expected able to be used for predicting the tsunami impact intensiveness at other areas. Keywords: fractal geometry, coastal line, tsunami, plate tectonics
