The Laboratory of Geosciences of Lanzarote (LGL) is an infrastructure resulting from the institutional collaboration between the CSIC, the UCM and the Cabildo Insular de Lanzarote.
The LGL was created in 1986 and has three permanent observation modules located in Cueva de Los Verdes, Jameos del Agua and the Timanfaya National Park.
Multidisciplinary research activities in geosciences are carried out its facilities, including, among others, observations related to geodynamic activity (gravity, seismicity, geodesy, etc.), the ocean-earth-atmosphere system, environmental monitoring in underground systems or studies of terrestrial analogues.

Geodynamics
 
Since 1987, the LGL has been developing and implementing geodetic and geophysical observation instruments and methods in its three observation modules. The research conducted involves obtaining continuous measurements of gravity, crustal deformations, sea level measurements, seismic and climatic parameters. The work carried out to date and those under development include:
·        Study of deformations of the earth's crust and variations of gravity in active volcanic zones.
·        Determination of the earth's crust structure through gravimetric inversion models by density contrasts, micro-seismic probing and magnetic data inversion.
·        Investigations of Earth tides, oceanic loading and vertical ground displacements for the study of the elastic properties of the upper earth's crust
·        Geophysical prospecting applied to the identification and characterization of volcanic structures combining georadar penetration, electromagnetic induction and microgravimetry.
 
 
Geomaterials
 
Within the Geomaterials Program developed at IGEO, a wireless network of microclimatic sensors was installed in the “Jameos del Agua” module to validate this monitoring system in underground environments.
The system installed consisted of 16 temperature and humidity sensors at different points in the cave to control environmental variations throughout the day. These sensors transmit the results to a server also installed in the same cave that has remote access for continuous monitoring and in real time from the Petrophysics Laboratory of the IGEO and the headquarters of the Casa de los Volcanes. Six temperature and humidity sensors were also installed using datalogger technology, placed both indoors and outdoors in the “Cueva de Los Verdes”. The results obtained show the validity of the wireless network system since the data reception was 100%.
 
 
 
Terrestrial Analogues
 
In order to select terrestrial analogues useful for the geological and astrobiological exploration of Mars, and within the studies that have been carried out in the Canary Islands since 1999, the LGL has begun activities aimed at their use in this field of research.
These studies will be based on geological, mineralogical, petrological and geochemical characterizations, testing of new prototypes, detection of biogeomarkers and the establishment of models extrapolable to Mars research, also integrating geo-educational and geoetic aspects. The dissemination of results will be carried out mainly through the IGEO and other institutions involved and will be complemented by the Spanish Network of Planetology and Astrobiology (REDESPA).
