In this work, we show the deep thermal profile of the Benis Cave (-350 m, Cieza, SE of Spain), which is related to the Benis Fault. This thermal profile was obtained from single rock point temperature measured over a period of 2 years. The temperature increases with depth, being, as a consequence, a reverse thermal profile. Based on this thermal profile, we have estimated that, over that period of time, the Vertical Geothermal Gradient is of 4.63ºC/100 m for the deep zone (-150-290 m). Furthermore, we have obtained a carbon dioxide profile, the values of which range between 650 and 880 ppm. Finally, on the basis of those data, we have calculated the Quaternary slip-rate for the fault-cave of Benis by estimating the shallow heat flow and the fault geometry. The slip-rate value ranges between 0.05- 0.04 mm/yr.
