Seismic tomography has proven in imaging subsurface features both in explorations and hazardous studies. We have modelled and assumed throughout study that most of earthquake during 2005-2010 in Java Islands and its surround are concentrated in south side of its continent. This is an indication that Indo-Australian plate gives massive impact in subduction processes in Java Islands. Slab detachment processes also have tight connection with thermal activity in Java Islands and its vicinity. Ring of fire and volcanoes existence which spreads in most area of Java Islands shown with appearing of low velocity region during slab translation.
Keywords: seismic, tomography, subduction, wave.
Analisis inversi AVO (Amplitude Versus Offset) dapat digunakan untuk
mengetahui penyebaran hidrokarbon pada data seismik. Konsep AVO
berdasarkan pada suatu anomali bertambahnya sinyal terpantul terhadap jarak dari
sumber gelombang ke geophone penerima (offset). Penelitian AVO ini dilakukan
pada reservoir lapisan TAF formasi Talang Akar.
