| Abstract | Modeling of MT. Merapi subsurface using receiver function method has been done. Receiver function is method to analyze subsurface structure using a station that consists of three components. To obtain receiver function response, data were rotated from (ZNE) (Z=Vertical, N=North, E=East) to ZRT (Z=Vertical, R=Radial, T=Tangential) component, and deconvolution between Radial and Vertical component is used. The inversion technique of receiver function response is used to obtain subsurface structure. The result of modeling indicates that in the North of MT. Merapi there is low velocity anomaly at depth 5-15 km. This anomaly is known MLA (Merapi Lawu Anomaly). |
