The Dolokapa Formation is a sedimentary rock formation formed in a deep-sea depositional environment with a fairly complex level of deformation and tectonic arrangement. Analysis of the sedimentation mechanism is carried out to determine how much tectonic influence on the mechanisms that occur in a depositional environment and the variations in the sedimentation mechanism formed. Research on the sedimentation mechanism needs to be carried out to determine the history of the formation of Gorontalo sedimentary rocks, especially in the Dolokapa Formation which was formed during the Miocene. The purpose of this study is to know the mechanisms of deep-marine sedimentation based on the identification of lithological characteristics, layer stacking patterns, and sedimentary structures. The method used was measuring sections using a range of ropes divided into four measurement paths. After that, a correlation was performed based on the genesis of deep marine formation. Based on the results of processing and analysis of the data, obtained units of lithology that insertion silty-clay, and the sandstone graining insertion of silt. In vertical succession, the layering pattern formed generally thickens upwards which describes the energy of the depositional currents. The sedimentary structure consists of rip up-clast, parallel lamination, graded bedding, convolute, slump, and trace fossils of nereites trace fossils of nereites that characterize the sedimentation of traction currents and turbidite currents in the deep-sea environment. The sedimentation mechanism formed is the traction current mechanism which is a further development of turbidite current and high-low concentration turbidity current mechanism that occurs slowly on a suspension-controlled grain. The stratigraphic relationship of the rock units in the research area is aligned based on the genesis formation that is located in the setting of the deep marine.

Gorontalo is one of the areas prone to earthquakes because Gorontalo has a geological structure, which is a fault. This fault has a northwest-southeast direction that cuts across the Gorontalo City area and crosses Lake Limboto. The research objective is to determine the direction of subsurface geological structures and analyze the impact of geological structures on the GORR development infrastructure. The research method is divided into several stages, namely, the preparation phase, the stage of data collection and the stage of data processing and analysis. The preparatory phase includes literature studies and regional geological studies. The next step is data collection in the field including lithology, geomorphology and structural data. And finally, data processing and analysis uses several classifications. Based on surface data, there are several types of lithology such as tuff, clay, and limestone which have started to decay. Geological structure in the form of fault / normal fault with northwest-southeast direction is also found in the study area. Based on subsurface data there are three types of layers namely clay sand, alluvial, and sandstone which are determined based on the classification of rock and mineral resistivity. Subsurface data also shows faults, in the same direction. And based on the vertical resistivity cross section shows the slip area seen from the resistivity value of the layer above it has a lower value than the layer below, it is very possible for landslides because the layer is more easily eroded and flowed, plus supported by a fairly steep field and rainfall in the GORR Region high enough.

North Sulawesi is an area close to the earthquake source due to tectonic processes such as active faults. This study aims to analyze the earthquake in Suwawa Timur from the earthquake depth and magnitude data. The method used in this research is a qualitative method by collecting and processing earthquake data. The analysis was carried out by creating a seismicity map of the Suwawa Timur area. The map shows that the earthquake points in Suwawa Timur are at shallow earthquakes (0 - 70 km) and moderate earthquakes (70 - 300 km). Shallow earthquakes are usually sourced from active seismic movement activity. Lithological conditions and structural geology affect the magnitude and depth of the earthquake value. Zonation map relates to the epicenter point of Suwawa Timur. Suwawa Timur is dominated by minor earthquakes (0.0 - 3.9), light earthquakes (4 - 4.9), and there is one point of a moderate earthquake (5 - 5.9).

Gorontalo has geological diversity that can be developed for geotourism. One of the tourist destinations of Gorontalo that has geological features is Pantai Indah. This study aims to examine the geological features in the Pantai Indah area based on the assessment of the value of science, education, tourism and the risk of degradation. The method used is geological observation and geological feature assessment issued by the Geological Agency. The research's results reveal that the landforms of Pantai Indah were composed of intrusion hills and marine plains. The lithology of the Pantai Indah area is granite and alluvial deposits. There is a geological structure that is indicated as a normal fault. The weighting of the criteria for the values of science, education, tourism and the risk degradation in the Pantai Indah area is 53.75%, 77.5%, 65%, 76.25%, respectively.
