''Some examples for the rainfall induced earthflows in the Western Blacksea Region of Turkey

Regional meteorological anomalies induce different types of mass movements. In May 1998, the Western Black Sea Region of Turkey has experienced such a type of meteorological anomaly. Numerous residential and agricultural areas and, engineering lifelines were buried under the floodwaters. Besides the reactivation of many previously delineated landslides, thousands of smallscale landslides mostly in earthflow type occurred in all over the region. The earthflows were mainly developed in flysch type units, which have already presented high landslide concentrations. In this study, three different catchments namely Agustu, Egerci and Kelemen were selected because these subcatchments have the most landslide prone geological units of the region. The targets of this proceeding are to describe the spatial distributions and statistical assessments of the shallow earthflows triggered. The unique condition units (UCU) were employed during the statistical analyses. The numbers of the unique condition units are 4052 for the Agustu subcatchment, 13241 for the Egerci subcatchment and 12314 for the Kelemen subcatchment. The earthflow intensity is the highest in the Agustu subcatchment (0.038 flow/UCU) while this value is the lowest for the Egerci subcatchment (0.0035 flow/UCU)
