Abstract

In this study, we derived crustal properties and shear wave velocity structures from analysis of teleseismic receiver function using Neighbourhoods Algorithm in the different geological units in Central Java. The results present here are the estimates of shear wave velocity models beneath 6 stations and the model of thickness of layer each geological unit. We observed the Moho depth at Central Java is about 22 to 38 km. In southern Central Java, the receiver function indicate a middle crustal low velocity zone, as Merapi Lawu Anomaly (MLA). The conversion Ps phase of the subducting Indo-Australian Plate is observed at several station at around 8.0 to 10.0 s. Several station that show high complexity data of receiver function require further study. They include stations at Quaternary Volcanoes and The Central Deppresion Zone of Java.
