A co-seismic fault slip distribution for the Mw 7.5 2018 Palu earthquake Dataset

Lin Shen, D.B.T. (Taco) Broerse, Wim Simons, Nicolai Nijholt, Riccardo Riva, Andy Hooper,
This dataset contains a finite fault model of the co-seismic slip distribution of the 2018 Mw 7.5 Palu earthquake. This finite fault model was used in the study of post-seismic surface displacements following the 2018 Mw 7.5 Palu earthquake (in Geochemistry, Geophysics, Geosystems entitled: A transient in surface motions dominated by deep afterslip subsequent to a shallow supershear earthquake: the 2018 Mw 7.5 Palu case).
This finite fault model was determined as an intermediate result in another study, on the co-seismic surface displacement and tsunami generation by Simons and Broerse et al. which is currently (Februari 2021) in preparation entitled: “A tsunami generated by a strike-slip event: constraints from space geodesy on the 2018 Palu earthquake”. This study combines co-seismic GPS offsets with a multitude of SAR-derived displacement fields in a Bayesian approach to infer the most likely fault slip distribution on a set of fault segments in NW Sulawesi.
