Structural and oceanic effects in the gravimetric tides observations in Lanzarote (Canary Islands)

Abstract

Since 1987, and as part of the research project that the I.A.G. is carrying out in the Canary Islands, records are obtained of gravimetric and ocean tides, pressure, temperature, etc. on the island of Lanzarote. The structural and geodynamic features of the island make our observations especially interesting because they may help to further research of the possible correlations of responses to tidal forces and other parameters such as crust structure and thickness, geothermic anomalies, etc. In this paper, we present the results obtained until now and a preliminary appraisal is given of these results in view of various previous hypotheses.
