ABSTRACT
Safety measures against the future disaster risk are considered as the main aspect of post disaster reconstructions. The majority of post-disaster villages/settlements and due projects on Sri Lankan coastline are apparently lacking behind the proper safety measures and adequate evacuation procedures. Therefore the immediate necessities of proper safety measures have to be emphasized in order to mitigate future tsunami risks. This paper introduces a number of post disaster coastal villages/settlements, which are in future coastline hazard risk, mainly in a future tsunami event. These include their location risk, land uses and housing designs defects and shortcomings of other safety measures. Furthermore few tsunami risk mitigation measures through land use planning strategies, which could be applied more easily in community level, are introduced. In addition to those the strategic development methods of functional networks of evacuation routes and shelters in different topographies are examined.
