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.

: 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.

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.

Study that collects, from a more general perspective, all the information on the problem of sand loss and the disappearance of beaches in the Maresme region. From a more specific level, the study focuses on the port of Masnou and the coastal dynamics correction measures that can be applied there.

The study focuses on floristic diversity and impacts on dune systems along the Catalan coast. Twenty-one dune-restricted plant species were identified as indicators of ecological integrity. A new index was applied to measure species diversity relative to total site biodiversity. Results indicate that dunes with less human activity retain more native species.

This study analyzes the historical transformation and current situation of the dune landscape in Catalonia.

The patterns of use and frequentation of beaches are a useful tool in coastal management and planning. The aim of this article is to apply the methodology for the analysis of physical carrying capacity in 16 beaches of the island of Menorca, based on the values in m²/user recommended in 2000. A multi-temporal analysis of the evolution of the beaches is carried out using qualitative variables that allow obtaining the trends of the beaches with parameters that analyze their management and occupation (2000-2017). The results obtained show that the beaches have acceptable carrying capacities and that environmental management, their publicity, and the services provided condition their spatio-temporal evolution. The methodology allows establishing future scenarios through the use of the analyzed variables.

Synthesis of the geological constitution of Catalonia through the cartographic representation of lithostratigraphic geological units, major structural elements (unconformities, faults and folds) and types of contact between units. The situation of the soundings carried out for the exploration of hydrocarbons is also included.

The study analyzes the evolution of the beaches of Sant Adrià de Besòs, Badalona and Montgat during the last decades to be able to characterize the problems encountered there, identify the most critical points and define initial proposals to solve the problem of regression they suffer.

Information regarding an area exposed to an avalanche. Mapped based on analysis of the terrain and of signs that avalanches leave in their path, mainly, in forests. In Avalanche Zones, avalanches occur frequently and are of different sizes. Avalanche Zones have been systematically mapped throughout the region. They are shown in orange. There are two types of Avalanche Zones: zones where avalanches usually follow the same path, shown in orange, and zones where avalanches usually follow different paths, shown in pale orange.
