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 District
Landslide that occurred on May 15th, 2019 in the Central Black Sea Region was examined.
This study aims to investigate the occurrence of landslide and its consequences. 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. Snowmelt
is the main factor that triggers landslides in the work area. 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 among preparative conditions 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. It has been proposed to establish new settlements far from
the landslide zone and the people in the landslide zone be moved to safe areas.
