Abstract
Description
The Lanzarote Island is the most eastern and oldest island of Canarian Archipelago. It present a recent volcanic activity during s. XVIII (1730-1736) and XIX (1824) Its geographic location, its volcanic origin and the condition of Reserve of Biosphere, give to the island of a special interest like Natural Laboratory of Investigation. From 1987 we are doing diverse geodetic and geophysic measurements in the island, focused in the study of the geodynamic activity, actual state and possible evolution. These investigation was the origin and development of the Lanzarote Geodynamics Laboratory (LGL). The LGL is a scientific-technical installation with an important techincal infrastructure, suitable instrumentation and installations, and long series of data. In the three observation modules we have more than 70 sensors (gravitymeters, tiltmeters, strainmeters, tide-gauge, weather stations, seismic stations, gps, etc) that register continuosly the respond in the surface to the geodynamic activity present. We present here the actual state of the investigations developed in the laboratory, with special focus to which have done in the National Park of Timanfaya, in relation with the recent volcanic activity, and in Jameos del Agua, laboratory dedicated to the observations of the sea level variations and the influence of the ocean in the geodetic and geophysic measuments.
