Present-day Tectonic Regime from Focal Mechanism Data in South Sulawesi

Focal mechanism used on tectonic regime study which is fault type determination in South Sulawesi. Fault parameter data consist of strike, dip and rake determined based on the first arrival polarity at earthquake waveform manually picked. The result were several beach-ball diagrams on 2010 - 2017 in...

Description
Summary:Focal mechanism used on tectonic regime study which is fault type determination in South Sulawesi. Fault parameter data consist of strike, dip and rake determined based on the first arrival polarity at earthquake waveform manually picked. The result were several beach-ball diagrams on 2010 - 2017 in South Sulawesi. Three reverse-oblique types, normal-oblique type and normal type caused by Palu-Koro Fault. In other pattern, there were Makassar Thrust: reverse type, two strike-slip types and four normal-oblique types. Walennae Fault signed by reverse type. Two reverse-oblique types and two normal-oblique types affected by Parang Loe Fault. All of them showed tectonic regime nowadays in South Sulawesi is complex.
