The LNEG, based on systematic geological and hydrogeological mapping (emersed and immersed area), as a support for the knowledge of the territory, intervenes in the characterization, inventorying and evaluation of geological hazards in general, competing to be the holder of up-to-date and detailed scientific knowledge in order to respond to scientific challenges and support public policies, and in particular:
In the characterization of seismic hazard
- Identify, characterize and recognize active tectonic structures, capable of generating seismicity and evaluation of associated hazard;
- Elaboration of neotectonic maps at different scales, active faults and Soil-site characterization.
In the characterization of mass movements in slopes
- Identification, characterization and recognition of sites susceptible to the occurrence of mass movements;
- Elaboration of maps of susceptibility of occurrence of mass movements.
The geological and geomorphological characterization of the coastal zone and the sustainable management of the coast
- The characterization and quantification of the coastal erosion mainly due to the climatic changes, regarded as a determining factor in the planning of the territory;
- Development of works, specifically in the quantification of the coastline retreat and in the volumetric determination of changes.
- Elaboration of maps in the scale 1:3000 with indicator of danger associated with the changes suffered at the coastline, over time.
Characterization of other risk situations
- Environmental geochemistry in areas of abandoned mines and marine and estuarine sediments;
- Floods, droughts;
- Contamination, over-exploitation and rehabilitation of aquifers.
Participates in national and international projects on hazards and natural geological risks. Additionally, LNEG intervenes in land use policies to organize the territory in a sustainable way, mitigating the catastrophic effects associated with geological risks.
