Özet:

Bagbası village located 11 kilometer northeast of Usak is under the threat of rockfall. The village is placed at an altitude of 1100-1190 metres on a volcanic mass. The volcanoclastic fractured rock masses placed on the eastern parts of the village roll over due to the influence of gravity and damage the houses by descending toward the accomodation units. Twenty-two houses are under this risk currently. The slope with topographic gradient changing between 35-45° is 1 km in length and 200 metres in width and is covered with unstable blocks. The distance of the rock blocks is varying between 15 and 150 metres. The mass of these blocks is between 0.5-25 m3. While some rocks under the danger of falling are bound with steel rope, the others are either broken with the help of hand tools or upheld with stones in order to prevent their movement. The rock fall case influences the geologic, geomorphologic, climatologic features of the area to a great extent. Earthquakes and shocks at the close stone quarry lead to the movement of the rocks. In case necessary precautions are not taken seriously, these rocks may descend toward the accomodation units at any time. The inhabitants in the village live in fear.
