Analysis of Landslide Disaster Vulnerability in North Tapanuli Regency Using a Grid-Based Geographic Information System Approach

Year: 2025

Type: article

Abstract: Landslides are natural disasters that cause material losses, casualties, and environmental damage. North Tapanuli Regency has a hilly and valley-filled topography that makes it prone to landslides. Data from the Regional Disaster Management Agency (BPBD) shows a high intensity of landslides, indicating the need for a study to identify the level of vulnerability. This study aims to map landslide vulnerability in North Tapanuli Regency using a Grid Base Geographic Information System (GIS) approach. This study uses a quantitative descriptive method with a spatial approach. The results of the study show that most of the area is classified as having a very high (52.13%) and high (42.31%) level of vulnerability, while the moderate, low, and very low levels of vulnerability only cover a small part of the area. These findings confirm that North Tapanuli Regency is highly prone to landslides, requiring serious attention from the government in disaster mitigation efforts.
