Abstract

Landslides cause loss of life and property from time to time. In Turkey, the Black Sea Region is the region where landslides are seen most frequently. In this study, Sağlık Neighborhood Landslide that occurred on May 15th, 2019 in the Central Black Sea Region was examined. This study aims to investigate the formation of the landslide and to discuss measures that can be taken in order to minimize the damage. For this purpose, area was visited and measurements were performed, soil samples and photos were taken. The region which has a rough terrain, receives precipitation throughout the year. The site has volcanic bedrock and thick debris and ground cover on it. The liquefaction limit of the soil is between 45.7 and 47.8 and the plasticity limit is between 20.51 and 22. Also, turning forests into agricultural areas, opening roads crossing the slopes, additional weights created by houses, water leaking from the sewer network to the ground and vibrations created by passing vehicles are among main causes of landslides. Stress cracks that started to occur in the crown part of the landslide three years ago started to expand on the day of the incident. The authorities who realized this evacuated the houses being under threat. Despite this, 22 buildings were destroyed and 8 hectares of agricultural land were damaged. To prevent damages, it has been proposed to prepare landslide susceptibility maps, to build new settlements away from potential landslide areas and to move residences in high-risk areas to safe places.
