Instability processes affecting the katskhi pillar monastery (Georgia)

The present work reports the main results of a preliminary hazard assessment affecting Katskhi pillar Monastery stability conditions in western Georgia (Imereti regions). The research activities have been carried out with the support of National Agency for Cultural Heritage of Georgia in Tiblisi, following field survey activities conducted during May and December 2012. The field mission was aimed at the identification of the following main issues: (1) collection of preliminary geological, geomorphological and geomechanical data in order to define the main strength and deformation parameters; (2) geodetic surveying with TLS techniques for the 3D model reconstruction of the site and collection of geometric data for future slope stability analysis; (3) seismic survey with passive technique to achieve information about resonant frequency of the site; (4) preliminary analyses of potential rock slope stability of the pillar; (5) preliminary monitoring project and assessment of stability condition with the implementation of a project proposal for a full analysis on long-term risk assessment for the Katskhi pillar Monastery.
