Landslide hazard mapping project was launched to study and identify the distribution of landslide potential in central highland of Sri Lanka.

This paper presents the results of the building survey carried out in housing units locate in very high and high landslide hazard prone areas of Hali-ela D.S Division in the Badulla District.
