Impact of tourism gentrification on Megathrust Disaster Risk in Pacitan Regency

Abstract

Pacitan Regency is one of the areas that has become the centre for the development of beach tourism in the southern region of Java Island. However, Pacitan is also a disaster-prone area, especially for earthquakes and tsunamis. The Pacitan area, in terms of geological conditions, is an area that has the potential to be affected by the threat of earthquakes, both centred at sea (subduction zones) and on land in the form of active faults. Pacitan Regency has the potential for a megathrust earthquake of 8.8, which can trigger a tsunami as high as 20 meters on land. The cycle of significant earthquakes and tsunamis originating from the subduction zone in southern Java occurs over a long time, where earthquakes are a repeating cycle that has the potential to happen in the future. Evidence related to past geological disasters from the south of Java is paleotsunami deposits in several places on the south coast of Java. Remains of tsunami deposits were found in Lebak (Banten), Pangandaran (West Java), Cilacap (Central Java) and Yogyakarta, to Pacitan (East Java). This study aims to (1) determine the level of vulnerability of the coastal tourism area of Pacitan Regency, (2) determine the level of social, cultural and economic capabilities of coastal communities and the government of Pacitan Regency, (3) develop the resilience of coastal communities and tourism communities to tsunamis and earthquakes. Megathrust in Pacitan Regency. Data collection was carried out by (1) field observations and measurements, (2) in-depth interviews with the community (3) secondary data collection. Data analysis used is spatial approach analysis, Geographic Information System (GIS) analysis, and hierarchy analysis. The study results show that Pacitan Regency is one of the fastest-growing districts. Tourism gentrification is one of the triggers for the increase in the gentrification process, which harms the megathrust disaster risk in Pacitan Regency.
