Estimation of the upper surface of Oceanic Plate using gravity anomalies and velocity model based on reflection and refraction seismic surveys

Abstract Based on reflection and refraction survey results, the shallow density structure model is created in Fujigawa-Kako fault zone. With the regional anomaly, which is calculated from bouguer anomaly and model gravity anomaly, the upper surface of Philippine-Sea-Plate is estimated, using forward modeling method under the density two-layer model assumption.
