In 2015 the sixth season of the renewed excavations at the Bronze Age city of Hala Sultan Tekke continued in the compound which was ex­posed in Area 6W in 2013–2014. Further evidence of textile process­ing was found. The results of another ground-penetrating radar (GPR) survey in 2014 indicated a new city quarter west of the former. Exca­vations were initiated there in 2015 and parts of the remains of a large compound were exposed. Two occupational phases, Strata 1 and 2, could be determined, both of which were destroyed in a conflagration. Further excavations were carried out in Area A, 550 m to the east of Area 6W and close to the mosque of Hala Sultan Tekke. In 2014 more than 80 circular anomalies were indicated by our geomagnetic survey supported by GPR. Twelve of them were excavated in 2015. Most of them turned out to be backfilled wells of which the fills mainly date from the 13th and 12th centuries BC (Late Cypriot IIC–IIIA). One of the excavated anomalies is interpreted as an offering pit. The preliminary date according to the pottery is roughly the 15th century BC (Late Cypriot IB).

Convective hydrothermal systems have been extensively studied using electrical and electromagnetic methods given the strong correlation between low conductivity anomalies associated with hydrothermal brines and high temperature areas. However, studies addressing the application of similar geophysical methods to hot dry rock geothermal systems are very limited in the literature. The Timanfaya volcanic area, located on Lanzarote Island (Canary Islands), comprises one of these hot dry rock systems, where ground temperatures ranging from 250 to 605 °C have been recorded in pyroclastic deposits at shallow (<70 m) depths. With the aim of characterizing the geophysical signature of the high ground temperature areas, three different geophysical techniques (ground penetrating radar, electromagnetic induction and magnetic prospecting) were applied in a well-known geothermal area located inside Timanfaya National Park. The area with the highest ground temperatures was correlated with the location that exhibited strong ground penetrating radar reflections, high resistivity values and low magnetic anomalies. Moreover, the high ground temperature imaging results depicted a shallow, bowl-shaped body that narrowed and deepened vertically to a depth greater than 45 m. The ground penetrating radar survey was repeated three years later and exhibited subtle variations of the signal reflection patterns, or signatures, suggesting a certain temporal variation of the ground temperature. By identifying similar areas with the same geophysical signature, up to four additional geothermal areas were revealed. We conclude that the combined use of ground penetrating radar, electromagnetic induction and magnetic methods constitutes a valuable tool to locate and study both the geometry at depth and seasonal variability of geothermal areas associated with hot dry rock systems.
