Tsunami Hazard Assessment and Mapping for the Southwest Coast of Sri Lanka Janaka J. Wijetunge Department of Civil Engineering, University of Peradeniya, Peradeniya 20400, Sri Lanka Email: janakaw@pdn.ac.lk Abstract. This paper is concerned with a deterministic analysis carried out to evaluate the tsunami hazard for the southwest coast of Sri Lanka. The hazard assessment is based on numerical simulation of tsunami inundation caused by the seismogenic ‘worstcase’ scenario for the coastline concerned, i.e., an event similar to the mega-tsunami in December 2004. The computed extent of inundation on the whole shows good agreement with the points of maximum penetration of inundation from field measurements in the aftermath of the December 2004 tsunami. It can also be seen that the inundation distribution is strongly influenced by onshore topography. Furthermore, numerical simulations of tsunami propagation indicate that formation of edge waves trapped by the primary waves diffracting around the southwest of the country significantly influences the nearshore tsunami wave field and is largely responsible for relatively higher tsunami amplitudes in certain stretches of the southwest coast of Sri Lanka. Keywords: coastal hazards, disaster mitigation, numerical modeling, tsunami inundation. 8
Mentawai Tsunami Wave Simulation Using Non-Orthogonal Curvilinear Coordinate Technique 1 Muslim Muin, 1 Hendra Achiari 1 Ocean Engineering Research Group Institut Teknologi Bandung Email: m_muin@ocean.itb.ac.id Abstract. Non-Orthogonal curvilinear coordinate ocean hydrodynamics model (Muin, 1997) was applied to simulate tsunami wave in Mentawai, in which occurred in 25 October 2010, 21:42:22 (GMT +7). The model was integrated in Geographic Information System, named as MuTsunami. The time step of the model was not limited by gravity wave speed. The results of simulation were compared with observational data. The field data was collected by group of researcher from Institut Teknologi Bandung, Waseda University, and Yokohama National University (Hendra, 2010). The studies present the results of simulation using various fault models. It was found that the agreement between the model and observations are very good for selected fault model Keywords: Tsunami, Modeling, Hydrodynamics 9
