Abstract

This study aims to determine strategic evacuation locations and optimal evacuation routes for visitors in the Klayar Coast area, Pacitan Regency, based on tsunami modeling scenarios with wave heights of 8.5 meters and 20 meters. This region has a high level of tsunami vulnerability due to its direct exposure to the Indian Ocean and its location within a zone of regional tectonic activity, while the intensity of tourism activities has led to a significant increase in the number of people exposed to risk. The study applies tsunami hazard zone modeling based on topographic and elevation data, combined with evacuation route network analysis using a Geographic Information System (GIS). Evacuation travel time was calculated by considering route length, topographic conditions, and average evacuation speed under emergency conditions. The results show that the 20-meter tsunami scenario causes a significant expansion of high-hazard zones and increases evacuation travel time by approximately 3.5–6 minutes compared to the 8.5-meter scenario. Several evacuation routes and Temporary Evacuation Sites (TES) that are effective under the lower scenario become suboptimal under the higher scenario. The novelty of this study lies in the integration of travel-time-based evacuation route analysis with multi-scenario tsunami modeling in a coastal tourism area, providing a more adaptive spatial basis for tsunami mitigation planning. These findings emphasize the importance of worst-case-scenario-based evacuation planning and the strengthening of early warning systems to enhance visitor safety.

Abstract

Forest and land fires represent a form of environmental disaster resulting from the interaction between natural factors and human activities in land use. Ngawi Regency, which is spatially dominated by agricultural and forested areas, exhibits biophysical and socio-environmental characteristics that may increase its vulnerability to forest and land fires. This study aims to assess the level of forest and land fire vulnerability in Ngawi Regency using a descriptive quantitative approach based on Geographic Information Systems (GIS). The analysis was conducted through scoring, spatial overlay, and vulnerability classification using the Equal Interval method applied to a set of biophysical and anthropogenic parameters. The results indicate that the study area is predominantly characterized by a moderate level of vulnerability, while areas with high and low vulnerability are more limited and spatially concentrated. The spatial pattern of vulnerability reveals a strong relationship between physical environmental conditions and the intensity of human activities. Areas located near settlements and road networks tend to exhibit higher vulnerability levels compared to areas with lower human influence. These findings highlight the importance of forest and land fire vulnerability mapping as a supporting tool for more targeted, adaptive, and sustainable mitigation planning aimed at reducing fire risk at the regional level.
