“…Several rupture models for the unbroken Mentawai segment have been proposed (Tobita, 2007;Aydan, 2008;Chlieh et al, 2008;Natawidjaja et al, 2009) and used by some researchers (Borrero et al, 2006;McCloskey et al, 2008;Taubenbock et al, 2009;Muhari et al, 2010) in an attempt to assess the tsunami threat to the major cities along the coast of western Sumatra, including Padang, Bengkulu and Painan. Tsunami arrival time, tsunami height and inundation map were presented for these proposed scenarios.…”

There exists a high probability of a great earthquake rupture along the subduction megathrust under the Mentawai Islands of West Sumatra in the near future. Six rupture models were used to assess the tsunami inundation and the accompanying sediment movement in Painan, West Sumatra, Indonesia. According to a worst scenario, the potential tsunami might hit the coast of Painan about 26 minutes after the rupture and the entire city could be inundated with a maximum inundation depth of about 7 m. Severe erosion may also occur in the near-shore region. Two scenarios, one scenario with a positive leading wave and the other with a negative leading wave, were selected to simulate the tsunami-induced morphological changes. A positive leading wave would cause severe erosion in the shoreline area and a large sandbar in the offshore area adjacent to the shoreline; a small amount of sediment could be deposited in the city area; a negative leading wave could cause moderate erosion in the further offshore area due to the strong retreating wave front, an offshore sandbar could form in the bay area, while no noticeable large area of sand deposit could be found in the city area. The difference in the erosion and deposition patterns between these two scenarios provides very helpful information in the investigation of historical tsunamis through tsunami deposits.

“…Jaya and Limin are both lecturers from the Palangkaraya 460 University in Kalimantan, where this forest fire occurred across the rain forest and impacted not only Indonesia but also the countries in the region such as Singapore (Tay, 1998) and Malaysia (Khandekar et al, 2000). Subarya, Natawidjaja, along with Sieh contributed the most (Briggs et al, 2006;Hill et al, 2012;Horspool et al, 2014;Hsu et al, 2006;Konca et al, 2008;Muhari et al, 2010;Nalbant et al, 2005;Philibosian et al, 2012;Prayoedhie et al, 2012;Schlurmann et al, 2010;Singh et al, 2010). 465 A closer examination on the list of ten most cited publications with Indonesian as first author shows a very striking picture.…”

Abstract. The number of disasters due to natural hazards and climate change are on the rise. Within the last decade the world has experienced the most frequent and impactful disasters. The year 2015 was the hottest year ever and the associated disaster impacts have drastically increased the cost to the society socially and economically. The Asia Pacific region has 10 been the place where these disasters occur the most. Indonesia, one of the countries in this region, is one of the most at risks from disasters and climate change impacts in this region.This paper aims to do a systematic literature review on published academic materials related to hazards, risks, disaster risks reduction (DRR) and climate change in Indonesia. Systematic literature review is defined as systematic or evidence-based literature reviews with explicit and transparent methods and follows a standard protocol or a series of stages so that bias can 15 be reduced and more importantly able to provide a comprehensive body of knowledge. While there is a vast material that have been published related to hazards and DRR on Indonesia, there has not yet a literature review that examines these materials in a comprehensive and systematic way. This systematic review is important since it outlines recent research progress over time which can help to determine which topics have been heavily researched and thus seeks to recommend future research needs. The author conducts a multi-staged literature review to study publications that are indexed within 20 SCOPUS. Multi-stage processes are taken to determine inclusion and exclusion for more relevant findings. The author also consults authors' and organizations profiles from Google Scholar, Research Gate, to determine gender, affiliations, and extent of publications.The first stage of search from Scopus gives a list of 5253 publications by which after second stage gives 1478 publications and third stage gives a final most relevant publication of 744. The findings are outlined in two parts. One on the results of the 25 analysis in terms of times of publications, most active researchers and research organizations, most cited papers, and categorization of major research topics. The other one is on the examinations on the roles of Indonesian authors and organizations in publishing in international journals, involvement in highly cited papers, and how collaborations have taken place amongst Indonesian and international researchers and organizations. This thus led to recommendations for capacity building in research in Indonesia. 30The findings on the first part are as follow. The final selected publications are categorized into three major topics of (1) hazard, risks and disaster assessments (HRD), (2) disaster risk reduction (DRR), and (3) climate change vulnerability, impacts and adaptation (CC). Publications on the category of HRD are comprised of more than half of the total publications, while the rest is divided amongst those related to DRR and CC. The oldest publication was issued in 1978 and the earlier perio...

“…In addition, in Goto et al (1997) the moving boundary approach developed by Iwasaki and Mano (1979) is used for inundation modeling. This method has been successfully used to run the tsunami simulation in several regions, including Padang, Indonesia, Mexico, and Japan (Muhari et al, 2010Goda et al, 2014;Mori et al, 2017).…”

“…Consequently, the potential impact of the future tsunami may be significant in this area. In addition, with the low-lying plain topographic features in Padang, the probability of large inundated areas and large inundation depths is also high (Borrero et al, 2006;Muhari et al, 2010Muhari et al, , 2011. In the past, two types of earthquake source scenarios have been mainly considered to develop tsunami risk mitigation plans in Padang: deterministic scenarios (Borrero et al, 2006;Schlurmann et al, 2010;Muhari et al, 2010Muhari et al, , 2011 and probabilistic scenarios (McCloskey et al, 2008;Griffin et al, 2016).…”

“…In Padang, 23 tsunami evacuation shelters (TESs) have been planned and built in the urban areas near the coastal line. However, an extensive assessment of the TESs in Padang during the tsunami event was not conducted by the previous studies (Schlurmann et al, 2010;Muhari et al, 2010Muhari et al, , 2011Imamura et al, 2011). Only horizontal evacuation time maps to safe areas were provided in Schlurmann et al (2010), excluding seismic and tsunami vulnerability assessments of TESs.…”

Abstract. This study develops tsunami evacuation plans in Padang, Indonesia, using a stochastic tsunami simulation method. The stochastic results are based on multiple earthquake scenarios for different magnitudes (M w 8.5, 8.75, and 9.0) that reflect asperity characteristics of the 1797 historical event in the same region. The generation of the earthquake scenarios involves probabilistic models of earthquake source parameters and stochastic synthesis of earthquake slip distributions. In total, 300 source models are generated to produce comprehensive tsunami evacuation plans in Padang. The tsunami hazard assessment results show that Padang may face significant tsunamis causing the maximum tsunami inundation height and depth of 15 and 10 m, respectively. A comprehensive tsunami evacuation plan -including horizontal evacuation area maps, assessment of temporary shelters considering the impact due to ground shaking and tsunami, and integrated horizontal-vertical evacuation time maps -has been developed based on the stochastic tsunami simulation results. The developed evacuation plans highlight that comprehensive mitigation policies can be produced from the stochastic tsunami simulation for future tsunamigenic events.
