“…Tsunamis generally occur after a large earthquake on the oceanic plate with a strength above 7 on the Richter Scale. Tsunami waves are able to ravage land areas because of its speed reaching 500 km/hour while reached the land [16]. To minimize the impact of the disaster, it is necessary to increase the buffer zone in coastal areas and settlements to responsive the tsunami hazard.…”

Settlement in coastal areas is at risk of a tsunami disaster. In urban areas, the risk of disaster can be greater than the area behind it. This study aims to analyze the priority of tsunami disaster mitigation based on settlements criteria in urban areas. The data collection technique uses a questionnaire given to experts in the field of disaster mitigation. The research variables consisted of occupancy typology, settlement locations, settlement patterns and density, coastal environment, evacuation routes and evacuation sites. Processing and analyzing data using statistical product and service solution software. The results of the regression analysis obtained that the settlement model Y = 3,055 – 0,410 residential typology + 1,119 settlement locations -0,017 settlement patterns + 1,323 settlement density + 0,040 coastal environment + 0,853 evacuation routes + 0,875 evacuation places. A high correlation was obtained on the location criteria and settlement patterns. Based on the mean value, the criteria for vertical evacuation places have the highest value, so can be recommended as a priority for the tsunami mitigation plan in urban settlements.

“…Large magnitudes have large deformation areas. One way to calculate the area is using the Well and Coppersmith equation (1994) [5] After the tsunami height is defined, the wave simulation of the tsunami is generated with the Gaussian hump equation [6] and then it is solved by the Shallow Water equation and Partial Differential Equation [7] that can be seen in (2.a) and (2.b) as the general equations. Gaussian hump is effective to make the distribution data of the parameter with mean and standard deviation factor and the Partial Differential Equation will simulate the tsunami in a couple times as the Shallow Water method as the simple one [11].…”

There was tsunami in Aceh in 2004 with the height reached to 30 meter. It was caused by a 9.2 magnitude earthquake on the Sunda megathrust. The tsunami destroyed most of the buildings in affected cities and claimed many fatalities. However, there were many tsunami incidents around Aceh before 2004. Aceh is located in the northern Sumatera Island of Indonesia. It is part of the Great Sunda Arc subduction zone, a convergent boundary between the Indo-Australian and Eurasian plates. Records of pre-instrumental tsunami in this region are scarce. Here we describe a tsunami in Aceh that happened in 1907. It was caused by a magnitude 7.6 earthquake on the Sunda megathrust, similar to the tsunami Aceh in 2004. Details of parameter information like the height, inundation, and the arrival times as the parameters after shaking was felt to some cities like Banda Aceh, Meulaboh and Gunung Sitoli are lacking and we want to calculate the these parameters to the cities although with the poor information. Based on the magnitude, the deformation and the possibilities of the parameter of the tsunami to the cities are calculated and modelled from Well and Coppersmith (1994) equation. After that we estimate the tsunami height, inundation and the travel time with Bayesian Markov Chain Monte Carlo and we get the result in the cities that the tsunami height is about 3 m, arrival times ranging from 20 second to 48 second and an inundation between 66 m to 127 m.

“…Areas right by the sea will bear the brunt of a tsunami, making communities near the coast more susceptible than those further inland. Tsunami waves, capable of reaching speeds up to 500 km/h, can severely damage structures and even push ships from the Meuraxa District port inland, as seen with the National Electricity Company's (PLN) generator ship during the last disaster [23].…”

The cataclysmic tsunami in 2004 profoundly impacted the city of Banda Aceh, resulting in significant redevelopment efforts in the coastal areas. This research examines the spatial development of settlements in these regions, mainly focusing on their vulnerability to future tsunami hazards. Surveys, literature reviews, and Geographic Information System analyses assessed how current urban growth aligns with the directives outlined in the Regional Spatial Layout Plan and disaster mitigation strategies. The findings reveal a notable escalation in settlement development within Banda Aceh City, with a 73.70% increase in directed sites. However, establishing sufficient tsunami rescue facilities has yet to accompany this growth adequately. Only 3.4% of the population has access to vertical evacuation infrastructure, highlighting inadequacies in the city's preparedness for future tsunami events. This deficiency in safety infrastructure poses an elevated risk to the expanding population residing in these areas. The study underscores the need to reassess urban planning and disaster mitigation strategies comprehensively. We emphasize the urgent requirement for the government to implement policies regulating urban expansion in high-risk coastal areas and enhancing the availability and distribution of vertical evacuation facilities. These measures are of utmost importance in safeguarding the lives of Banda Aceh's residents against potential future tsunamis, thereby contributing to the city's sustainable urban development and resilience. The study also provides valuable insights and recommendations for government policymaking in urban planning, focusing on prioritizing the safety and well-being of coastal communities in regions prone to tsunamis.
