“…Salah satu software yang dapat digunakan adalah TUNAMI-N2 (Imamura et al, 2006). Software ini pernah dipakai untuk mensimulasikan penjalaran tsunami di beberapa tempat di berbagai belahan dunia yang rawan tsunami (Fu et al, 2017;Heidarzadeh dan Satake, 2017;Selvan dan Kankara, 2016;Pribadi et al, 2016;Prerna et al, 2014). Software ini dapat digunakan untuk menentukan ketinggian dan waktu tiba gelombang tsunami.…”

Indonesia merupakan salah satu wilayah rawan bencana gempa bumi dan tsunami. Wilayah beresiko tinggi terjadi gempa bumi dan tsunami berada di laut Sulawesi dimana terdapat zona subduksi Sulawesi Utara. Salah satu cara mitigasi tsunami adalah dengan mensimulasikan ketinggian dan waktu tiba gelombang tsunami. Karena berada di wilayah laut Sulawesi maka Tahuna beresiko mengalami bencana tsunami. Pemodelan gelombang tsunami menggunakan software TUNAMI-N2. Hasil yang didapatkan menunjukkan bahwa, ketinggian gelombang yang dapat menerjang Tahuna adalah 0,23 m dengan waktu tiba sekitar menit ke-50Indonesia is one of the area that prone to disaster like earthquake and tsunami. The area with high risk for earthquake and tsunami to occur is located ini Sulawesi Sea where there have a North Sulawesi Subduction Zone. One way to mitigating tsunami is to simulate the height and arrival time of tsunami wave. Because of its position located in Sulawesi Sea, Tahuna City is very likely to struck by tsunami. The modelling of tsunami wave using TUNAMI-N2 software. The result yield the height of tsunami that could struck Tahuna City is 0,23 m with arrival time around 50 minutes

“…Increased urbanization along these coasts enhances the risk to communities and the built environment of tsunamis and storms. Managers often base risk assessments of different coastal hazards on the power-law magnitude–frequency relationships exhibited by datasets of storm wave height or sea-level exceedance (Burbidge et al, 2008; Prerna et al, 2015). However, tsunami waves do not follow this magnitude–frequency relation, and thus it cannot be used to calculate the frequency or return period of tsunamis based on the historic or observational record, or to identify hazard risk based on run-up elevation alone (Nirupama, 2009).…”

Different political, economic, social and environmental factors are considered in plans for coastline reconstruction following tsunami events. These competing factors inevitably result in a compromise being made with respect to reconstruction policy and practice. Coastline reconstruction may also be constrained by availability of technology, speed of action or decision-making, local political expediency, and external influences such as disaster relief policy and the roles of NGOs. In some cases, it could be argued that such compromises result in inappropriate actions or decisions being taken that do not always consider the dynamics of coastal processes. An outcome is that expensive geoengineering structures may hinder long-term coastline recovery, and may result in future increased coastline vulnerability. Here, based on examples of the 2004 Indian Ocean and 2011 Tōhoku-oki tsunamis, we argue that inappropriate reconstruction after such events may have serious long-term negative effects that can contribute to increased future risk for inhabitants of tsunami-prone coastlines.

“…Besides, the Andaman and Nicobar Islands (ANI) of India was signi cantly damaged by the earthquake and subsequent tsunami (Ramanamurthy et al 2005). The damage include land uplift, subsidence, destruction of coral reef, beach erosion, sediment transport deposition, damage of dunes and mangroves (Nirupama et al 2006;Dharanirajan et al 2007;Bahuguna et al 2008;Prerna et al 2014;Mageswaran et al 2015). The geomorphic changes in ANI was studied by using pre & post-earthquake remote sensing datas and quanti ed their areal extents (Narayana, 2011).…”

We report here a four decades of shoreline changes and possible sea level rise (SLR) impact on landuse/landcover (LULC) in Little Andaman Island by using remote sensing (RS) and GIS techniques. A total of six remote sensing data sets covering years between 1976 and 2018 were used to understand the shoreline changes. Moreover, a Digital Shoreline Analysis System (DSAS) was used to estimate short-and long-term shoreline changes from ArcGIS environment. Besides, the Island vulnerability due to SLR was studied through using digital elevation model (DEM). As a result of Sumatra earthquake ( 2004), the results were showed a signi cant variation in shorline upliftment and subsidence. The land subsidence was noticed in the range of 1042-3077 ha with sea level rise between 1 and 5 m. Hence, we conclude that Little Andaman Island is vulnerable to SLR and overwhelm low elvation coastal zone.
