Preliminary result for crustal properties derivation related to tectonics for hazard mitigation in Eastern Indonesia using Teleseismic P Coda

Eastern Indonesia is tectonically complex, formed by different plates and microplates interactions from origins. This complexity gives geoscientists a challenge to solve the ’jigsaw’ of complex interactions. The understanding tectonic processes can lead breakthrough in both resource exploration disaster risk reduction. We utilize teleseismic P wave coda for random scattering deterministic originated crust-mantle boundary (Moho) derive crustal properties, including thickness, Vp/Vs, qualitative characteristics. For we apply Iterative Cross-Correlation Stacking (ICCS) align waveform. At same time, crust characteristic, employ Receiver Functions (RF) method alongside H-k stacking. thickness recovered RF stacking has good correlation with origin, where older stable Sundaland Gondwana thicker than younger plate arc subduction origin. Vp/Vs high region that interpreted be dominated mafic lower oceanic-oceanic during Eocene, anisotropy, or magmatic anomaly. also correlated well subsurface anomaly providing unique pattern.
