A key realisation of this work for me has been that earthquake-triggered slides cause a very substantial proportional (probably in fact the majority) of fatalities is mass movement events. Attention is drawn to the importance of both the education and training of the local people in the recognition of signs of potential movement and a reporting management system. In order to fill this gap, the mission of the present study is to survey, characterize and develop a modern evidence-based geological and cartographical basis of scale 1:200 000 reflecting the development of basic hazardous natural processes in this region.
