Abstract

Landslides are a ubiquitous natural phenomenon in some parts of the hill country in Sri Lanka. The objective of the study is to identify landslide prone micro areas in the Haldummulla divisional secretarial division in the Badulla district located in the hill country.  It comprises 04 villages with a total population of 1375 spread over a land area of 4.8 km. An analysis of the data revealed the existence of four landslide prone micro-areas; sites of landslides in the past, high, moderate and low. The National Building Research Organization (NBRO) and field investigations revealed two areas where landslides have occurred during the last 5 years. High - and moderate hazard areas cover 97 percent of the total area. As high and moderately vulnerable areas are not suitable for settlements, cultivation or for commercial purposes a disaster management plan is essential.

Key words: Haldummulla; GIS; High Hazard; Moderate hazard; Low hazard; Disaster
