Seismic and Tsunami Hazard Potential in Sulawesi Island, Indonesia
Journal of International Development and Cooperation, 2011
From the middle of 1970's until now, the Sulawesi Island which is surrounded by several small and big tectonic plates had been struck 270 times by earthquake above 5.0 in magnitude. This number of occurrence tends to get higher and higher each year, beginning after the raising activity of Sunda Arc over the past last six years, which recently struck Padang, West Sumatera in September 2009. The goal of this study is to find out the most potential areas for seismic and tsunamis activities in Sulawesi Island, by analyzing the historical data of earthquakes and tsunamis at the areas and also base on the fault system on it. It was found out that the earthquakes with magnitude above 5.0 in the next ten years will occur minimally 49 times; with almost all of them will be sea-epicenter which could generate tsunami in some areas. The most potential areas will be the North Arm of Sulawesi, especially in the coasts of North, South and East.

Proceedings of the International Conference on Social Sciences, Humanities, Economics and Law, 2019
The experience of a large earthquake has occurred in the past few years. Along the subdiction of the west coast of Sumatra, the 2004 Aceh Earthquake and tsunami, the Bengkulu Earthquake in 2007, the Padang Earthquake in 2009 and the Mentawai Earthquake and tsunami in 2010. Based on the research results of Nanyang Technology University and the Indonesian Institute of Sciences in Padang, the Mentawai Megatrusht subduction predicted to be 8.9SR. Such conditions, the City of Padang Government needs to prepare mitigation measures in efforts to reduce disaster risk. Qualitative interpretive research methods, data sources consist of primary data and secondary data. Primary data in the form of interviews and secondary data from the documentation review. The results showed that the Padang city government had prepared mitigation efforts carried out in the form of determining disaster-prone areas, the rules for building construction by earthquake standards, training, and disaster education, determining evacuation areas and evacuation routes. The Padang City Government has also installed earthquake evacuation signs and the making of SOPs in disaster-prone areas.
Preparedness of the community in facing disasters like earthquakes (Case: Cisarua, Indonesia)
Jàmbá Journal of Disaster Risk Studies
The potential for disaster in an area is based on the geographical characteristics of a place and the living factors of the surrounding community. Community preparedness must be implemented to minimise the impact of an earthquake. This study aimed to determine the level of community preparedness in facing earthquakes in Cisarua District, Indonesia, based on the results of earthquake hazard mapping. The research used the quantitative Analytical Hierarchy Process (AHP) for earthquake hazard mapping and disaster preparedness using questionnaires. The AHP parameters include earthquake acceleration, distance from the Lembang fault, rock type, soil type, land use, slope and population density. The sample for this study comprised 80 respondents from six villages with a relatively high level of vulnerability, namely the villages of Jambupida, Padaasih, Pasirhalang, Pasirlangu, Kertawangi and Tugumukti. Data collection was carried out through interviews and site surveys based on a questionna...
EARTHQUAKE, TSUNAMI, AND SOCIETY COOPERATION EARLY FINDINGS IN PALU POST OF INDONESIA DISASTER.pdf
Geographically, the Sulawesi Island is located on 5.36LU-7.48S and 117.02-125.74E. It is one of the safest islands due to its location that is not directly related to two oceans, namely the Pacific Ocean and the Indian Ocean. Sulawesi is divided into six provinces and has several small islands. This makes it one of the islands with the longest coastline in Indonesia. However, this is what causes Sulawesi Island to be susceptible to marine disasters, such as high waves and tsunamis triggered by submarine earthquakes whose distribution can be seen in figure 3. In this study, we tried to examine how the society established cooperative relationships with various social elements that existed, a few days after the disaster occurred. In addition, data collection was conducted through interviews, focus group discussions (FGD) along with scientific findings or research that had previously been conducted so that the results of the research became more accurate and systematic. This article was the initial findings so that it only presented data from sources in a homogeneous manner. An earthquake with a magnitude of 7.5, followed by a tsunami, hit the West Coast of Palu, Central Sulawesi on September 28, 2018.. As reported by the Meteorology and Geophysics Agency (BMKG) report, the quake was not only felt in Paluas the epicenterbut also in some surrounding regencies and cities, namely Donggala, ParigiMoutong, Sigi, Poso, Tolitoli, Mamuju, Samarinda, Balikpapan, Gorontalo, and Makassar.

Analysis of Padang City community preparedness to face the earthquake and tsunami disaster
E3S Web of Conferences, 2021
Padang, West Sumatra is located in the collision area of two tectonic plates, namely Indo-Australia and Eurasia. Which is marked by the presence of a tectonic earthquake center in the Mentawai islands and surroundings. Realising the high risk of disasters, the people of Padang city must be ready and prepared for the possibility of an earthquake and tsunami. To reduce the risk of disaster, the use of “self-help” and “mutual-help” parameter might be the best way to help the people to know “what should they do?” and “how can they do it?” to protect themselves from disasters. This research aims to analyse the Padang city community’s preparedness to face the Earthquake and Tsunami disaster by using “self-help” and “mutual-help” parameters. A questionnaire consisting of 20 questions was used to collect the data. The sample size of this research is 400. The data was collected from 4 different areas (Random area, Pondok area, Purus area, and Ulak Karang area). The study found that the Padan...

A tsunami is a disaster that can be hardly estimated. It is a significant concern UN since more than 60% of the world's population lives in coastal areas prone to tsunamis, including Indonesia. The county community with complex and dynamic plate requires mastering of mitigation strategies as a tsunami preventive effort. Understanding the vulnerable elements in risky areas is critical. However, the magnitude of potential disasters cannot be minimized. This study analyzes the tsunami vulnerability in Bantul, Special Region of Yogyakarta (DIY). The analysis was based on a description of assessment parameters such as land use, the physical condition of the area, social conditions, and availability of infrastructure. The results show that social vulnerability had the most significant impact.

Post-event Field Survey of 28 September 2018 Sulawesi Earthquake and Tsunami
Natural Hazards and Earth System Sciences Discussions
An earthquake with a magnitude of M W = 7.5 that occurred in Sulawesi, Indonesia on September 28, 2018, triggered liquefaction and tsunamis that caused severe damage and many casualties. This paper reports the results of a posttsunami field survey conducted by a team with members from Indonesia and Taiwan that began 13 days after the earthquake. The main purpose of this survey was to measure the runup of tsunami waves and inundation and observe the damage caused by the tsunami. Measurements were made in 18 selected sites, most in Palu Bay. The survey results show that the runup height ranged from 2 to 10 m and that the inundation distance was between 80 and 510 m. The highest runup (10.5 m) was recorded in Tondo, a complex that has many boarding houses near a university. The longest inundation distance (511 m) was found in Layana, a marketplace. The arrival times of the tsunami waves were quite short and different for each site, typically about 3-8 minutes from the time of the earthquake event. The characteristics of the damage to buildings, facilities, and structures are also summarized. Several indicators of underwater landslides are described. The survey results can be used for the calibration and validation of hydrodynamic models for tsunamis. They can also be used for regional reconstruction, mitigation, planning, and development.
