AB The spatial distribution of groundwater temperatures in the volcanic island of Tenerife, CanaryIslands, has been inferred through measurements of water temperatures collected in the vast network of wellsand subhorizontal tunnels, locally called ‘‘galleries,’’ which constitutes the main water supply of the island.The spatial coverage of the network of galleries allows us to reach from depth almost any geological featureof the island. The complex spatial distribution of temperatures in the interior of Tenerife is the result of thecomplex geological evolution of the island. Groundwater temperatures are greatly affected by groundwaterflow and are considerably warmer in those galleries located in areas where water circulation is reduced due tothe low permeability of materials and/or to the low infiltration rate of cooling meteoric water. In this sense,groundwater temperature should be characterized in quiescent conditions (background level), in order tofacilitate monitoring changes in heat flow, such as those induced by ascending gases expected with an increasein volcanic activity.
