Abstract
The subduction zone occurs in Java Island analyzed based on data of tectonic earthquake. Earthquake data used is P wave velocity accessed from the ISC website from 1900-2013 years located along the Java Island. ISC is an organization that provides a variety of data tectonic earthquakes around the world, but the data used is the data before relocation. Relocation needs to reposition the hypocenter, so it can result a new position based on geological model. The relocation is using Jacobian's matrix and AK135 velocity model of P wave in each depth. The tomography process using FMTOMO software from result of new hypocenter represent the subsurface condition at a depth of 0-700 km. The result of hypocenter relocation is shifted horizontally to the southeast while vertically relatively shallow. The results obtained from the tomographic analysis of north-south section show the response of the velocity wave where high value shown in blue color as subduction zone and low value shown red color under volcanic as the partial melting. Tomographic 3D visualization displayed by Voxler software shows the different subduction in Java Island. Result of 3D analysis indicate that the subduction in West Java until Central Java relatively sloping than subduction in East Java.
