Abstract

ABSTRACT. The idea that speleothems may record earthquakes is rather old, but it was only after 1950 that system­atic studies started on this topic. Presently it's well accepted that karst speleothems (especially stalagmites) can be used as a tool for tectonic and seismic analysis. In the present paper an overview on the state of the art in the seismotectonic and paleoseismic analyses using naturally broken speleothems and/or still growing stalagmites is presented. Specifi­cally they may be important with respect to:

location and epicentre of past earthquakes;

their relative and absolute dating (within the last 500,000 yr. or so);

magnitude of these earthquakes;

improvement in the seismic hazard evaluation.
