Three underground cavities in the northern Calabria region have been selected for speleoseismic analysis. Deformed speleothems as well as collapsed stalagmites were observed and sampled in the Romito and the S. Paolo caves in the Pollino Range area, and in the Monaca cave in the Catena Costiera. Deformed carbonate speleothems were sampled and dated by the U/Th method in order to constrain paleoearthquakes which shocked the cave sites and the surrounding area. Medium to large earthquakes have been recognized in the study area by paleoseismic and archaeoseismic studies. Moreover, frequent instrumental small to moderate seismicity occurs in the area. In 2010 a three year seismic sequence struck the area very close to the Romito and San Paolo caves.
