Abstract

Vertical thermal profiles of active faults and geothermal gradients are related to the tectonic fault slip (Pérez-López et al., 2017). We have measured temperature at different depths (each 10 m), by using SEABIRD SBE56 high accurate loggers (±0,002 ºC, temp. range -5 y +35 ºC). We used the FAM-1 borehole (Martínez-Díaz et al., 2016), with 174 depth and a dia- meter of 8.8 cm. The borehole is located 3 km south-westward of the city of Lorca, and the Alhama de Murcia Fault intersects the borehole at -60 m. We measured each 10 m depth during 190 minutes, in two different yearly seasons. The geothermal gradient is 3.86 °C/100m, slightly higher than results from Henyey and Wassemburg, (1971): 2.7 °C/100 m in 300 m, and 3.6 °C/100m in 450 m, in the S. Andrés Fault.
