THE GREAT SUMATRAN FAULT DEPRESSION AT WEST LAMPUNG DISTRICT, SUMATRA, INDONESIA AS GEOMORPHOSITE FOR GEOHAZARD TOURISM

Two approaches can be taken to understand geotourism, namely the geological approach and the geographical approach. This approach will lead to the creation of new geotourism products, initiatives, and experiences, one of which is geohazard tourism involving faults and earthquakes. To identify geomorphosites, the researchers examined rocks, outcrops, and geomorphology. Then various thematic maps are created using mapping software and other drawing applications to simplify textual material and aid synthesis. A synthesis of all that is then carried out to reconstruct the geological and geomorphological history of the study area. Furthermore, the West Lampung geomorphosite candidate was compared to the worldwide fault and earthquake geomorphosite theme. The Great Sumatran Fault depression landscape can be found in Balak Pekon, Batubrak Regency, and Pekon Padang Dalom, Balik Bukit District, West Lampung Regency. This depression is caused by both endogenous and exogenous factors. The endogenous activity takes the form of sediment from volcanism and fault movement, whereas exogenous activity takes the form of river water erosion. The valley's sediments are ignimbrite tuffs/sandy tuffs that form a cliff morphology with a height of + 75 meters and a trend of Southeast-Northwest. In the case of geotourism, initiatives have grown over time around two complementary approaches (geological and geographic) and the result is a geomorphosite in the geohazard area. One of the areas is the Sumatran Great Fault depression geomorphosite, this area was formed due to the movement of the Sumatran fault which caused the 1908, 1933, and 1994 earthquakes. Situations like these can be used as opportunities to enhance learning about the relationships between people, land use, natural processes, and large-scale events by providing real-life examples, this can be packaged into the form of geohazard tourism.
