ABSTRACT
Historical tsunami database records that tsunamis hit Padang city in 1797 and 1833. Even though the Padang city government had released a tsunami evacuation map for the city, it has not provided complete information for the estimated tsunami inundation areas and the inundation depths. Additional analysis is needed to improve the information on the city tsunami zones in tsunami inundation maps. The inundation maps in this study are divided into three maps based on the numerical simulations of the tsunami from the sources of Pagai and Sipora blocks (2 maps), and topographic data (1 map). Due to these, each tsunami event was simulated in four areas, namely: 1) Ulak Karang; 2) Air Tawar; 3) Parupuk Tabing, and 4) Pasir Jambak sub-districts. Based on the results of this study, it is found that the coastal areas of Ulak Karang and Air Tawar are lower-lying areas than the coastal areas of Parupuk Tabing and Pasir Jambak. The directions of the inundation distribution and run-up in the simulations are influenced by the direction of the tsunami waves generated by the tsunami sources. The tsunamis on land will be further in a low-lying area, then propagate before finally stopping at high relief. Although overall tsunami inundation based on topographic data inundates a wider area, there are many shortcomings of the simulations, such as the direction of the tsunami inundation on the mainland, soil roughness factors, and building barriers, which are not considered parameters.
