“…From the analysis of coulomb stress changes in zone 3 obtained an increased value of Coulomb stress that ranges from 0.1 to 1 bar indicated by red and coulomb stress decrease ranges between -0.1 to -1 bar indicated by blue. Zone 3 with normal fault type N6E/32 South-North [24]. Analysis of coulomb stress change distribution showed increased stress and decreased stress by perpendicular to each other.…”

This study aims to analyze the distribution of earthquake events, analyze seismicity based on the parameters of b value, analyze changes in Coulomb stress and analyze the risk of earthquake events in South Sulawesi based on seismicity levels and changes in Coulomb stress in the range of 1991-2021. The data used in this study is data on earthquake events in 1991-2021 obtained from the IRIS and ISC catalogues. Data from the IRIS catalogue is mapped using ArcGIS software to see the distribution of the next earthquake spread processed by using MATLAB-based ZMapp 7 software to obtain the value of seismicity parameter (b value). Data from the ISC catalogue is mapped using Google Earth software to see the spread of earthquakes and then processed using MATLAB-based Coulomb 3.1 software to obtain analysis of stress Coulomb changes. Based on the results of the analysis obtained a value of b between 0.9-1.5 shows the value of b obtained is relatively low which correlates with a high level of stress. Based on the results of the analysis of changes in Coulomb stress obtained the movement of increased stress towards the red lobe with a value of 0.1 to 1 bar and decreased stress towards the blue lobe with a value of -0.1 to -1 bar. In general, earthquake-prone areas are located in the northern to central parts of South Sulawesi.

“…Hal tersebut menyebabkan kondisi yang tidak stabil karena sistem tektonik yang bekerja tidak sama (Massinai et al, 2017). Sesar walanae terletak di sebelah selatan Sulawesi Selatan yang membentang dari Selat Makassar, Mamuju, Majene, Pinrang, Sidrap, Bone, Sinjai, sebelah timur Pulau Selayar, dan Bulukumba (Lorna et al, 2019). Karena kondisi geologi tersebut menjadikan Kabupeten Bulukumba tergolong rentan terhadap ancaman bencana gempa yang berpotensi tsunami.…”

Sempadan pantai merupakan wilayah daratan yang paling dekat dengan laut sehingga sangat rentan dengan bencana seperti tsunami. Menurut sejarah, Kecamatan Ujung Bulu sebagai bagian dari Kabupaten Bulukumba pernah mengalami bencana Tsunami pada tahun 1820. Penelitian ini bertujuan untuk memprediksi tingkat kerentanan tsunami di Kecamatan Ujung Bulu sebagai salah satu upaya mitigasi yang dapat dilakukan. Metode analisis yang digunakan adalah weighted overlay dengan memanfaatkan teknik tumpang susun (overlay), scoring, dan pembobotan pada peta jarak dari garis pantai, jarak dari sungai, ketinggian, dan kemiringan lereng dengan menggunakan teknologi GIS. Hasil penelitian ini mengelompokkan kerentanan terhadap bencana tsunami di Kecamatan Ujung Bulu dalam 3 tingkatan kerentanan tsunami yaitu kerentanan tinggi 49,43%, kerentanan sedang 35,14%, dan kerentanan rendah 15,43%.
