[Proceeding] – Preliminary study results of crustal structure beneath Mount Merapi, Central Java, Indonesia

Penulis: Sandy Kurniawan Suhardja et. al.

In this study, we put an effort to estimate crustal depth and image crustal structure beneath Merapi volcano by employing multicomponent analysis popularly known as Receiver Function technique. We collected a series of waveforms from teleseismic events recorded from October 2013 to mid-April 2015 at 53 stations as a part of DOMERAPI project. We processed selected seismograms by simple deconvolution process between radial and vertical components to estimate the depth of Moho discontinuity beneath the volcano. Current results show complex structure beneath the volcano and a relatively potential Moho depth at about 30 km, which becomes shallower to the North at about 23 km. Stations located at Southern and Northern area show potential low velocity zone though a velocity modelling is necessary to confirm its depth and how low the velocity is.
