: Information regarding an avalanche observed in the past. Mapped based on a survey of inhabitants of the area where the phenomenon took place. The boundaries shown are based on the explanations given by the witnesses consulted. Information is usually taken from Avalanche Zones close to inhabited areas where avalanches have historically interfered with human activity. For this reason the majority of the information is found around these zones. They are shown in purple. Cartography often maps only the avalanche arrival zone, as the descriptions usually refer to their extent and the damage caused.

Information regarding an avalanche observed recently. Mapped based on direct observation of the event or observation following it. The information is obtained based on the nivometeorological observation network, rescue groups, countryside wardens, mountain guides, and ski and mountain resort personnel. In the event of important episodes and accidents the IGC technicians also gather information. The elements mapped mainly include the extent to which avalanches affect populated areas, roads, ski resorts and people who carry out mountain activities. Data began to be gathered in 1986. It is shown in blue.

This study analyzes the sediment loss associated with the removal of Syringodium filiforme berms from 10 beaches in the Dominican Republic. The results show that approximately 63.8% of the removed volume corresponds to interspersed sediment. This type of management has a continuous morphological impact, affecting the stability of the system's sediment balance.

The study analyzes changes in the forest landscape of the Costa Brava over the past century through the comparison of historical and contemporary photographs. The results show a significant increase in forest cover, with the recovery of pine and oak forests, while agricultural areas have declined. This suggests a shift in land use and in the tourist perception of the landscape.

Soil information on soil profiles described in the field, with varying degrees of detail, both of the place where the observation is made and of the profile described. Including its composition in horizons, morphological description and physical-chemical characterization, such as the type of soil.

This study analyzes the historical management of coastal dune fields on the Catalan coast to understand their changes over time.

3D model of Port del Comte aquifers, developed as part of the assessment of underground water resources available in Catalonia. More specifically, this model contains the lithological-hydrogeological units, the main geological structures, the topographic surface of the project area, the location of the main karst springs and the saturated rock volumes of the water reservoirs associated with each of the springs

The study analyzes the floristic composition and vegetation structure in the dune spaces of the Llobregat Delta, highlighting the changes caused by natural and anthropic factors. The impacts of exotic species, especially invasive ones, are also discussed.

1D/2D geophysical data, obtained through the application of different geophysical methods in different locations in Catalonia, consisting of the measurement of different physical parameters of the subsoil to obtain information on the behavior of its materials and its structure throughout the territory. Specifically, this set of information includes data, profiles and models resulting from the application of the following geophysical techniques: Magnetotelluric (MT); Electrical Tomography (ERT); Vertical electric sounding (SEV); Seismic refraction Survey (SRA); Seismic reflection survey (SRX); Surface wave analysis (MASW); H/V spectral quotient; Passive seismic array (ARRAY); Geophysical testing in wells.

The Map for the Prevention of Geological Risks is a document that represents the geological hazard of the territory at a scale of 1:25,000. It is a multi-hazard map, which offers an overview of the hazards identified in the territory. The territory is zoned, for each hazard considered, into high, medium and low hazard, and is represented according to traffic lights. The symbology used allows the type of phenomenon causing the hazard to be identified, while the phenomena and indicators of this hazard are represented.
