Determination of the Risks That Are Emerged from the Use of Aerial Photographs in the Mapping Activities for Landslide Movements by FMEA and Pareto Analysis Methods and Suggested Solutions

Abstract

The emergence of landslides; take part among flooding, earthquakes, tsunami, volcano eruptions, storms, etc... that usually play adverse role on the life of the societies. In general, the landslides emerge due to the flow, collapse, slide or fall of the filling materials in the hillside that lose their stability. The monitoring of the landslides in pre-emerging stage and to ensure taking precautionary measures that they do not cause any harm in the infrastructures are so important with regard to human life and dwelling places of the society. Assessing the aerial photography alongside with the topographic measurements on the landslide stricken areas or on the fields of having landslide potential becomes very important during the evaluating, understanding and making inventory and sensitivity mapping of the landslides. There are some risks, especially in the assessment of aerial photography and making high quality inventory and sensitivity maps alongside with the landslide field studies. In the study, it is attempted to provide sufficient information on definition, evaluation and taking precautionary measures by FMEA and Pareto Analysis for difficulties and risks that are relevant with the aerial photography alongside with the landslide field studies.
