Sediment thickness in the eastern part of Kalimantan from high-frequency receiver functions

Abstract We analyze high-frequency receiver functions from two seismic stations to characterize the sediment properties around eastern coast of Kalimantan. First, we compute teleseismic events using time-domain deconvolution method. The obtained are then stacked H-κ stacking approach determine properties. computed show complicated waveforms for station located near Kutai Basin. These may indicate presence multi sedimentary layers. results suggest that is thinner in northern part area (∼1.34 km depth) than southern region (∼3.0 depth). consistent with previous geological and geophysical studies conducted this region. works suggested thickness study can reach up 9 km.
