“…Data released by BMKG revealed that the earthquake would continue to strike as long as the geological conditions in the disaster-prone area were unstable. The BNPB also said that the number of victims would continue, and victims reported missings due to liquefaction that followed (Rusydi, Efendi, Sandra, & Rahmawati, 2018). Secondly, this report rendered the community anxious and restless.…”

The earthquakes that occur in the Indonesia are caused by several primary factors such as the tectonic plate shifts which lead to the increased activity of earthquakes and volcanoes. Moreover, the geological condition and the rock structure of swathes of Indonesia constitute the secondary factor that contributes to the danger of the disaster in Indonesia. Various disasters having occurred in the last 2 years are summarized in this article. This study was aimed to provide information concerning the history as well as attempts to cope with disasters and impacts on society following the disasters in Indonesia. The qualitative case study methodology was selected along with sources derived from various community groups as well as governmental agencies such as BNPB (The National Agency for Disaster Countermeasure) and BMKG (Meteorological, Climatological, and Geophysical Agency) that serve as a reference in this study. The results of the study delineated that the community’s response to the natural disasters led to increased security mitigation efforts made by the community and the government. In addition, it affected social relationship between communities in a positive manner evidenced by participation in helping with the post-disaster recovery.

“…Sulawesi Island is located at the convergence of three plates: the Indian-Australian Plate, the Pacific Plate, and the Eurasian Plate [33]. Consequently, the island has several active faults, including the active Palu-Koro fault located in the northwest area of Palu (Figure 2) [34].…”

A Mw 7.4 earthquake hit Donggala County, Central Sulawesi Province, Indonesia, on 28 September 2018, triggering a tsunami and liquefaction in Palu City and Donggala. Around 2101 fatalities ensued and 68,451 houses were damaged by the earthquake. In light of this devastating event, a post-earthquake map is required to establish the first step in the evacuation and mitigation plan. In this study, remote sensing imagery from the Landsat-8 and Sentinel-2 satellites was used. Pre- and post-earthquake satellite images were classified using artificial neural network (ANN) and support vector machine (SVM) classifiers and processed using a decorrelation method to generate the post-earthquake damage map. The affected areas were compared to the field data, the percentage conformity between the ANN and SVM results was analyzed, and four post-earthquake damage maps were generated. Based on the conformity analysis, the Landsat-8 imagery (85.83%) was superior to that of Sentinel-2 (63.88%). The resulting post-earthquake damage map can be used to assess the distribution of seismic damage following the Palu earthquake and may be used to mitigate damage in the event of future earthquakes.

“…Faults found on tectonic plates in their development also experience movement and will contribute to earthquake events (Farid et al, 2016). e magnitude of the earthquake that occurs due to the mechanism of the movement of the fault depends on the area of the asperity area where the greater the area of asperity (Arunee et al 2019), the greater the probability of the earthquake occurring (Rusydi et al 2018). e mechanism of this fault movement can be in the form of strike-slip, reverse, and normal (Irsyam et.al.…”

Lawanopo Fault is a horizontal shear fault (sinistral strike-slip) found in Southeast Sulawesi province and is thought to be active during Plio-Pleistocene or mid-late Miocene to the present. This study has been carried out which aims to find out the geometric shapes below the surface of the Lawanopo fault using complete Bouguer anomaly (ABL) data. The ABL data is projected onto a flat plane using the Dampney method at an altitude of 8 km, and the separation of local and regional anomalies is carried out using the upward continuation method at an altitude of 60 km. Three-dimensional (3D) modeling under the surface of the Lawanopo fault is done using the computer program Grablox. Data processing techniques using Singular Value Decomposition (SVD) and Occam inversion. The results showed that a high gravity anomaly of 190-225 mGal was caused by an igneous rock below the surface with a density of 2.7-3.33 gr/cm3 and a thickness of about 13 km, a moderate anomaly of 175-187 mGal caused by Paleozoic igneous rocks aged Carbon with a density of 2.6-2.9 gr/cm3 and a thickness of about 25 km. Low anomaly 115-160 mGal is caused by rocks with a density of 2.0-2.5 gr/cm3 and a thickness of about 22-23 km. The Lawanopo fault constituent rocks consist of alkaline rocks in the basement covered by sediment and metamorphic with a depth of Lawanopo fault more than 15 km and begin to be seen at a depth of 4.3 km of the surface. it is known that the area around the Lawanopo fault is an area prone to earthquakes. But, based on the soil and rock structure around the Lawanopo fault, the compactness and attenuation levels in reducing earthquake waves are quite good, so that land use around the Lawanopo fault tends to be safe.
