“…Probabilistic functions were utilized within the software to introduce uncertainties and variability in the selection of the restitution parameters. Calibration of parameters followed the existing scientific literature [57][58][59][60] and works previously carried out in similar geological zones [61]. Table 1 details the parameters utilized in the modeling, according to the lithological units identified in the study zone.…”

In recent years, there was an increasing number of studies focusing on rockfalls due to their impacts on social and sustainable development. This work carries out a three-dimensional (3D) simulation of rockfalls at a cultural heritage site nearby the village of Cortes de Pallás (Valencian Community, East Spain). The simulation is based on data collected previously, during an emergency declaration due to the occurrence of a considerable rockfall (7980 m3) on the southern bank of the Cortes de Pallás reservoir, on 6 April 2015. The hydroelectric power plant was damaged, and the main access road to the village of Cortes de Pallás was blocked for eight months. The predominant discontinuities of the rock mass were analyzed by means of the application of structure from motion (SfM) photogrammetry techniques to the set of images taken by remotely piloted aircraft systems (RPAS). The average size of the block was determined as 3.2 m in diameter and 17.6 m3 in volume. Additionally, a digital elevation model (DEM) was generated from an aerial laser scanning (ALS)-derived point cloud using a 1 × 1 grid. These data were implemented in RocPro3D software, obtaining the distances traveled by the blocks detached from different source areas at a cultural heritage site located near the rockfall event, which presents the same geological context. The simulation presented herein shows aggravating circumstances that endanger the cultural heritage area, with higher rockfall hazards than previous official studies (1991) displayed.

“…Hard rocks predominate, especially Jurassic limestone and dolostone, which constitute the framework of the mountains. These conditions determine frequent rockfalls, which have caused significant damage, specifically to the road network [18,30,126].…”

“…Rockfalls are dangerous phenomena due to high kinetic energy related to the velocity of the falling bocks. This often explains the difficulty of taking fast-enough and effective actions and of designing appropriate protection and mitigation measures [17,18]. After detachment, boulders may move by falling, bouncing, rolling, and sliding.…”

Effects of Wildfire on Rockfall Occurrence: A Review through Actual Cases in Spain

Understanding processes and conditions that lead to rockfalls during and after a wildfire in different geological contexts is crucial since this phenomenon is one of the major hazards in mountainous regions across Europe. Spain is one of the European countries with the highest rate of wildfires, and rockfalls cause high economic and social impact, with many fatalities every year. The increase of rockfalls during and after wildfires is connected with the merging of different factors, not only in the detached area but also in the propagation and potentially affected area. When wildfire occurred, many actions take place: changes in the mechanical conditions of the rocks, the loss of protective capacity from vegetation, the effect induced by firefighting activities and/or the impact by the high temperatures in the adopted protective measures. After the wildfire, there is an increase in frequency and intensity of rockfalls in the burned area, causing a major impact of rockfalls on not only road networks and built-up areas but also people living. Additionally, the removal of vegetation by wildfires causes an increase in the risk perception, related not only to detached blocks but also to the general appearance of the rock mass. In this review, the main factors that influence the occurrence of rockfalls after a wildfire are analyzed, and three actual case studies in Spain are presented to support the variety of conclusions obtained.

“…The values of the dynamic rolling friction, the normal and the tangential energy restitution coefficients are usually obtained from the literature (Asteriou et al, 2012;Guzzetti et al, 2003;Guzzetti et al, 2004;Mateos et al, 2016;Santangelo et al, 2019;Sarro et al, 2014Sarro et al, , 2018. Since the information the literature does not provide any reference value for volcanic materials, we have derived these parameters indirectly from the geotechnical map.…”

The island of Gran Canaria (Canary Islands, Spain) is characterized by a large variability of volcanic rocks reflecting its volcanic evolution. The geological map provided by Geological Survey of Spain at 1:25.000 scale shows more than 109 different lithologies and it is too complex for environmental and engineering purposes. This work presents a simplified geotechnical map with a small number of classes grouping up units with similar geotechnical behaviours. The lithologies were grouped using about 350 rock samples, collected in the seven major islands of the Archipelago. The geotechnical map was used to model rockfall hazard in the entire island of Gran Canaria, where rockfalls are an important threat. The rockfall map was validated with 128 rockfall events along the GC-200 road, located in the NW sector of Gran Canaria. About 96% of the events occurred along sections of the road where the number of expected trajectories is high or moderate.
