- The aims of this research are to determine the changes of tsunami risk in coastal area of Pacitan and to evaluate it by considering land suitability for settlement. Comparative method was used to analyse between existing risk from land use map and potential risk from land suitability for settlement map. These comparison also considered the regional spatial plan of Pacitan Sub-district. Tsunami hazard map was taken from previous research to build the tsunami risk scenario. Tsunami hazard could be classified into five level, i.e. very low, low, medium, high, and very high. Based on this model, the research area is dominated by very high level of tsunami hazard. The results showed that Pacitan Sub-district has land suitability for settlement at the moderate level (S2) and not suitable (S3) level. Land suitability with level S2 is highly potential for settlement development that might result in tsunami risk change. Refer to the risk analysis result, it can be seen that actual and potential element at risk is going up between 2014 and 2034. The actual increase is about 123 Ha while and potential increase is about 1.342 Ha. If there is no control at developing of settlement, there are very wide area of settlement development will be built in the high level of tsunami hazard area. As consequence, the risk of the tsunami will be higher as well.
