S11JDY ABOUT TIlE RELATIONSHIP AMONG CRUSTAL TIlICKNESS. HEAT FLOW AND GRAVIMETRIC TIDE IN THE ISLAND OF LANZAROTE

Data from heat flow and gramivetric tides are at our disposal in the island of Lanzarote (Canary Islands); its formation is known and, in addition to it, a model of its. crust which provides us with its thicknes is at our disposal. When studying the relationship among these parameters, a disagreement with the results obtained from previous studies is observed; those studies show a clear relationship between positive anomalies in the cosine component of the M2 and 01 waves of the gravimetric tide harmonic development and high values of heat flow; while the heat flow values determined in the island are abnormally high, the cosine components of the residues for these waves, determined by observation, have no abnormal values, and in the case of M2 wave, a negative value. On the other hand, the measured heat flow values are as expected, once the island crust thickness and its recent volcanic activity have been seen.
