Measuring strain and stress from sinkhole distribution, Example of the Velebit mountain range, Dinarides, Croatia.

The sinkholes appear to be a sensitive indicator of the recent tectonic activity. Their spatial distribution allows us the measurement of strain and stress to which the studied area has been submitted during recent periods. Our analysis is based on the center to center method (Ramsy, 1967 ; Fry, 1979), dealing with the determination of strain ellipse. This method is applied to the analysis of topographical changes in distribution of sinkholes. As a result we have obtained a considerable number of local results. To pass from a local to a regional level we have used Panozzo’s projection method (Panozzo, 1984). Both of these methods were adapted to the study of sinkholes. The results represent a very good base for the interpretation of recent local and regional deformation of the studied zone.
