Abstract

Administratively, the research location is situated in the Maen area and its surroundings, Likupang Timur District, North Minahasa Regency, North Sulawesi, with UTM (Universal Transverse Mercator) coordinates 51 N 732393 mE – 736394 mE and 179973 mN – 183983 mN using the WGS 1984 datum. The research area covers an area of 4x4 square kilometers. Maen village is located in an area rich in energy and mineral resources potential. Previous geological mapping in this area was conducted on a regional scale. Therefore, the author is interested in conducting detailed mapping at a 1:10,000 scale in the Maen area and its surroundings, Likupang Timur District, North Minahasa Regency, North Sulawesi. The geomorphology of the research area comprises four geomorphological units: Piroclastic Flow Ridge unit, Lava Flow Ridge unit, Coastal Plain unit. The stratigraphy in the research area consists of four rock units arranged from oldest to youngest: Coarse Tuff unit, Lapilli Stone unit, Andesite unit, and Lake Deposit unit. The geological structure in the research area includes weathered joint fractures oriented generally northeast to southwest. Geological history in the research area began in the Pliocene epoch with the deposition of the Coarse Tuff unit, followed by the deposition of the Lapilli Stone unit in the Pleistocene epoch, and simultaneous deposition of the Andesite unit in the same Pleistocene period. The topmost layer consists of Alluvial Deposit unit deposited from the Holocene epoch to the present.

Abstract

The Sangihe Islands Regency, North Sulawesi Province, is situated between the Talaud Islands Regency and Biaro Islands Regency. This region hosts several active volcanoes, such as Mount Banua Wuhu and Mount Awu, the latter being the highest point in Tahuna District. This study focuses on the volcanic geology, specifically the facies of Mount Awu, conducted in the Bungalawang area of Tahuna District. The methodology involved field surveys encompassing direct observations of surface geological conditions, followed by laboratory analysis and studies. The identification of volcanic facies was based on geomorphology, volcanic rock stratigraphy, and geological structures. Research findings indicate that the study area falls within the distal facies of Mount Awu. The stratigraphy of the area comprises units such as Volcanic Rock Unit, Tuff Santiago Breccia Insert, Santiago Tuff Insert Breccia, Tuff Manente Breccia Insert, Manente Tuff Insert Breccia, and Alluvial Unit. Geomorphological identification, geological structure analysis, and stratigraphy reveal that the study area constitutes a distal facies located at the foothills of Mount Awu. Geological structure analysis indicates the presence of fractures showing a main stress direction towards N3240E. The geological history of the study area began with the formation of the Volcanic Rock Unit due to the eruption of the ancient Sahendarumang volcano. Subsequently, a series of eruption and deposition events formed distinct stratigraphic units. This research contributes significantly to understanding the geological and geological history of the region. Its findings are applicable in various practical applications, including disaster mitigation and natural resource development. This study also serves as a foundation for further research in the field of geology, particularly Volcanology.

Abstract

Geotourism is increasingly popular in modern tourism because it allows tourists to understand and appreciate the unique geological features of a region. This study aims to explore the geotourism potential based on the cape landscape and sheeting joint phenomenon on Sangihe Island, North Sulawesi. Focusing on a case study of Cape Lelapide, the research involves field surveys, rock descriptions, joint structure analysis, geotourism analysis, and literature review. The research findings indicate that Sangihe Island has significant geotourism potential due to its stunning cape landscapes and sheeting joint phenomenon. The cape landscapes offer beautiful natural scenery, while the sheeting joint phenomenon provides evidence of tectonism based on previous studies. Tectonic features are indicated by the predominant N1200E orientation of joints from 100 measurements, interpreted as resulting from northwest-southeast directed stress, suggesting the subduction of the Philippine Plate beneath the Eurasian Plate (Molucca Sea Suture). Rock distribution at Cape Lelapide includes lava igneous rocks and occurrences of Calcite Vein and several vesicular structures indicating ancient volcanic activity of Sandarumang during the Quaternary-Tertiary period. Geotourism assessment highlights significant potential across various aspects, including scientific research, education, tourism, and risk degradation. With high value in scientific and educational aspects, coupled with promising tourism potential, this location is attractive for research and learning. However, attention is needed to address degradation risks, particularly due to its coastal location exposed to high wave erosion and inadequate legal protection.

Abstract

Administratively, the research area is located in Ratatotok District, Minahasa Tenggara Regency, North Sulawesi. Geographically, the research area is situated at UTM (Universal Transverse Mercator) coordinates 51N between 687000-691000 meters easting and 98000-102000 meters northing, covering an area of 4 x 4 square kilometers (16 km²). The objective of this research is to understand the geomorphology, stratigraphy, geological structure, and geological history of the study area. The geomorphology of the research area consists of four geomorphological units: Karst hill unit, Karst plain unit, Intrusive hill unit, and Alluvial plain unit. The stratigraphy of the study area comprises three rock units arranged from oldest to youngest: Crystalline Limestone unit, Porphyritic Andesite unit, and Alluvial Deposit unit. The geological structure in the study area includes fractures oriented generally northwest to southeast and a suspected uplift fault. The geological history of the study area began in the early Miocene epoch with the deposition of the Crystalline Limestone unit, followed by the emplacement of hypabyssal intrusions forming the Porphyritic Andesite unit during the early to middle Miocene epoch. In the Holocene epoch, alluvial units were deposited non-conformably, accompanied by erosion processes shaping the morphology of the study area, which continue to the present day.

Abstract

Disasters are events that can harm affected communities, caused by natural, non-natural, or human factors. Several dominant factors contributing to vulnerability to landslides or soil movements include rainfall intensity, slope steepness, soil type, as well as geological and geomorphological conditions. Taas District, as the study area, exhibits potential landslide hazards that require assessment. This research utilizes assessment methods and leverages Geographic Information System (GIS) tools. The study results, based on classification according to Minister of Public Works Regulation No. 22/PRT/M/2007, indicate low and moderate landslide vulnerability classes within the research area. These findings provide valuable insights for further mitigation efforts.
