Resumen
We have carried out a paleoseismic analysis of the Benis Fault, located at the southeast part of Spain. We have estimated the last earthquake size-magnitude and time, from evidence of celling collapse and displaced broken carbonate blocks (M6 and 65 ± 18 ka BP). Our analysis suggests that the tectonic slip-rate of the Benis Fault is lesser than 0.01 mm/yr. Additionally we have measured the deep thermal profile of the Benis Cave (-350 m of vertical development, Cieza, SE of Spain), from single rock point temperature measurements in different field campaigns and for a period of 2 years. The temperature increases with depth, being in consequence a reverse thermal profile in comparison with normal gradients in deep caves. Furthermore, we have estimated the Vertical Geothermal Gradient with a value of 1.85ºC/100 m for the deepest zone (-150-290 m). Finally, we have calculated the heat flux of 0,46 mWm2.
