“…With this geological structure analysis, the pattern formed because of the formation of the Great Sumatran Fault can be determined. One of the most valuable methods to see the formation of geological structures in this Great Sumatran Fault area is to use analysis of Landsat 8 OLI / TIRS C2 L1 satellite imagery 15)- 16) , which displays geological conditions in the form of results such as geological maps, geological structure maps, geomorphological maps, and maps of - This research aims to see indications of the appearance of fault structures using visual satellite image data located in the Pulau Padang Village and its surroundings. Field geological observations are also carried out to record geological condition data in the form of lithology types, geological structures that develop, flow patterns and geological structures that are currently developing at the research site so that they can integrate the analysis of geological data obtained from visual data from Landsat images combined with field data.…”

The Great Sumatran Fault is the main fault on the island of Sumatra, which stretches throughout the island, and one of its products is Central Sumatra Basin. The research area is an area that developed from the Central Sumatra Basin at the time of its formation, and this research area is in Pulau Padang Village. This study focuses on the geological and structural developments due to the Central Sumatra Basin. Central Sumatra Basin is the main producer of oil and gas in Indonesia. River straightness patterns, lithological offsets, and others can indicate the fault structure. Based on satellite image data and digital elevation models, there are indications of fault structures appearing in the research area and its surroundings. This can be seen from the straightness of the Bukit Mudoh's river. This anomaly is visible in the river's flow pattern, which shows a significant change in the upstream area, which is in the form of a trellis, then changes instantly to a straight line. Based on the appearance of the Landsat 8 OLI/TIRS C2 L1 satellite image, there is a hill offset that shifts with the movement of the fault. This is also supported by data supporting the tectonic framework of the Central Sumatran Basin, which indicates a compression phase during the Middle Oligocene to Middle Miocene with a North-South direction of stress and reactivation in the Pliocene-Pleistocene.
