2016 Kaikura Earthquake Tsunami Simulation from Point and Finite Fault Source Models

Ergin Ulutaş [1] , Beran Gürleme [2]


In this study, The numerical simulations of November 13, 2016 Kaikoura, New Zealand eaerthquake (Mw: 7.8) have been performed. The earthquake occurred at a depth of 15 km at the transition between the Alpine fault in the South Island and the Kermadec-Tonga subduction zone. The approximation of non-linear long wave equations is performed and adopted to simulate tsunami propagations with an initial displacement of the ocean bottom deformation due to faulting. Co-seismic source models proposed by United States Geological Survey (USGS) are further used to represent the effects of various slip models on tsunami prediction along the coastal regions of New Zealand. The maximum value of the initial heights are calculated as 1.18 and -0.2 meters for uplift and subsidence areas from uni-form point source models. However, these maximum values are 1.01 and -0.1 meters from finite-fault source models. We have also compared our simulated tsunami waveforms with the observed tide gauge records. The results show that non-uniform slip models could be more effective in prediction of the tsunami heights compared to uniform slip models where the earthquakes involve complex rupures as in Kaikoura earthquake.
