Correlations of Slab Thermal Structures with Varying Seismic Patterns in Indonesian Subduction Zone

The Indonesian subduction zone exhibit significant variations of slab thermal structures along strike with corresponding varying seafloor age and convergence rates. We investigate the along-strike variations on (1) seismogenic zone of interplate thrust earthquakes, (2) seismicity as a function of depth, (3) slab geometries as revealed by Wadatti-Benioff zones, (4) slab stress regimes as revealed by intermediate-depth and deep earthquakes, and (5) spatial distributions of arc volcanisms relative to trench. All are deemed as a function of slab thermal parameter. By using up-to-date seismic data, we expect to have a result of more detailed spatial resolution for observed patterns that are previously analyzed ((2), (3), (4)) and of more insight understanding on the patterns those that are not analyzed previously ((1), (5)). In any case, the compiled observations will be used to attest proposed mechanisms for their occurrence or formation.
