Abstract
ABSTRACT Sulawesi located between Eurasia Plate and Pasific Plate is possibly the most complex in the eastern Indonesian, which island arc rocks, melange, ophiolite, and pieces of microcontinent carried along with subduction and collision process. Based from new interpretation from seismicity and tomography, there are reversal arc in Gorontalo Bay and double subducion in Molluca Sea ( Hall & Spakman, 2015). Relocated earthquake data can be used to analyze structure in subduction zone. This study using simulated annealing rellocated method to obtain new hypocenter points. Simulated annealing method based on themodynamical process of substance forming. Data process using matlab R2009b software. Tomography aims to display the results of data processing relocation. Software tomography used in this study is FMTOMO. Earthquake data used in this study is the earthquake data from 1900 to 2013. The data used is the P wave data taken from ISC (International Seismological Center) with the number 3031 earthquake events. Relocation using simulated annealing method shows that new hypocenter point moved 2 km southeast from original locations. Based from tomography result, there are double subduction at slice D-D’ and E-E’ also reversal arc at slice A-A’. Keywords: Simulated Annealing, Travel-Time, Subduction Zone, FMTOMO
