Rockfall is one of the main phenomena in mountainous environments due to its fast and high speed of movement, its unpredictability, and, therefore, the difficulty of identifying signs of instability and detachment of the blocks. Compared to other types of sliding, the proportion of rockfall research is smaller and sometimes little known, but, in the last five years, rapid growth in this area has been shown. Therefore, this research aimed to review the intellectual structure of rockfall, through analysis of scientific production using bibliometric techniques that allow its analysis, knowledge, global evolution, and future trends in rockfall. The research methodology consists of three steps: (1) data compilation, (2) software and data cleaning, and (3) analysis, interpretation, and visualization. This analysis focuses on the period from 1975 to 2019. For the data, a total of 811 academic publications were retrieved from the Scopus database. The results indicate an increasing trend of annual publications on rockfall. This analysis reveals the main topics, countries, and most influential institutions in the world that have carried out relevant research in scientific publications; it also shows the journals that have the most publications. VOSviewer software was adopted to evaluate the co-occurrence of author keywords. Currently, the hotspots rockfall issues mainly include: hazard-risk assessment, remote sensing, and rockfall monitoring. Finally, this article analyzes the limitations of current research and proposes a future direction for the development of new research.

Santa Elena Peninsula is characterized by beautiful geological features, historical geoscientific knowledge, and mineral and tourism resources that could all be combined for the sake of community development. This article provides an overview of the Santa Elena Peninsula Geopark Project through the assessment of six areas that are considered by inhabitants and researchers possible geosites to foster geotourism. The methodology included: (i) a technical description and assessment of the areas of interest evaluating their geological relevance, representativeness, geotouristic prominence, geotouristic scientific interpretation, and conservation criteria; (ii) an assessment through questionnaires carried out on inhabitants; and (iii) a SWOT Plus analysis to propose strategies for promoting geotourism. Results show that the areas of interest are highly valued as geosites, since they integrate geodiversity, biodiversity, and sociocultural aspects. For example, Ancon is a historical icon of early oil exploitation, Baños de San Vicente is a natural spring of thermal water and mud volcano, and Anconcito has bituminous exudations of natural occurrence together with a spectacular landscape produced by erosion. Overall, 90% of these sites were proved to be of high and very high interest in scientific terms. Geotourism is believed to be beneficial for the inhabitants of the Santa Elena Peninsula with respect to education, valorization of resources, and the strengthening of cultural identity of communities.

The purpose of this article is to provide an overview of academic research on volcanic geomorphology, through the use of bibliometric analysis and bibliographic visualization maps for the discernment of its growing interest by the academy in the last 30 years. It is sustained on the publications indexed in the Scopus database between 1956 and 2019, obtaining relevant information on scientific production, following the methodological structure of a rigorous bibliometric process, which ranges from the search for descriptors or keywords to the configuration of visualizations of tables and maps that allowed to consider the contributions by authors, institutions, journals and topics that have shaped the evolution of this field of study. The generations of bibliometric maps allowed understanding the intellectual structure of the field of study made up of 707 articles where the analysis of co-occurrence of author keywords showed six main lines of research that, combined with the co-citation maps, allowed understanding the breadth of intellectual structure. Extensive information is provided on the thematic that other investigations partially addressed or failed to capture their current status. Considering that the results allow us to identify areas of current interest and the potential of research in volcanic geomorphology.

Zaruma is host to the ‘‘El Sexmo’’ tourist mine, the galleries of which extend below the city, and its exploitation dates back to precolonial times. The mining boom created important development in the area, but informal mining also emerged causing environmental issues and safety problems. This study presents a qualitative and quantitative assessment of the “El Sexmo” Tourist Mine in the context of its potential as a tourism geosite and mining site. The methodological stages included: (i) The process and systematization of the general mine information and its surroundings; (ii) the assessment of the geological and mining interest of the mine, through GAM and Brilha method; and (iii) description and proposal of action strategies through Delphi analysis and a Strengths, Weaknesses, Opportunities, and Threats (SWOT) matrix. Based on the results of the quantitative evaluation, the high values in the educational, scientific, and tourist aspects of the two applied methodologies, show the mine as a potential geosite and mining site with added cultural value. In addition, the quantitative assessment in correspondence with the qualitative analysis, allowed to propose improvement strategies to take advantage of the geological resources and mining identity of the area, as an alternative that strengthens the infrastructure of the mine and consolidates the geotouristic development of the area.

Resilience has several meanings, among them the ability to overcome difficulty and return to the state of providing service, even if the initial conditions change. Assessing resilience in an ecosystem, or any system, requires a concise methodology with standard variables and parameters. The current challenge presented by coastal areas is focused on overcoming problems related to the water supply through correct management. This paper aims to evaluate the communal coastal aquifer system with a matrix for assessing water resilience based on indicators in the Sustainable Development Goals (SDGs) in a socio-hydrological framework and the four axes of development (political, social, environmental, and cultural), to promote the development of new strategies for water sustainability. The method is based on (i) political, economic, social, environmental, and even cultural aspects involved in sustainable water management and (ii) the groundwater resilience assessment method (GRAM) design. The GRAM is used for a quasi-quantitative assessment of the resilience in a communal coastal aquifer system. This method was applied to the Manglaralto community; the results show a highly resilient groundwater system (62.33/100 points). Representatives of the community have achieved appropriate use, management, and conservation of the water resource by applying water harvesting and other technical criteria. Hence, they have avoided aquifer overexploitation and provided water to the community.

Inefficient blasting techniques and poor closure management of the old quarry that existed during the 1970s in the area of the actual General Patrimonial Cemetery of Guayaquil resulted in an almost vertical slope of approximately 50 m in height and an intense induced fracturing that weakened the rock mass. This led to the loss of stability and increased material detachment, which damaged the infrastructure of the graveyard representing a risk to visitors and workers. The aim of this research is to evaluate the slope stability through a geotechnical analysis that allows decision-making to recover and preserve the safety of the area. In this work, we used structural measurements and observations made in the field, as well as a three-dimensional model of the slant generated by photographs taken by a drone. Slope Mass Rating (SMR) and Chinese Slope Mass Rating (CSMR) rankings were used to evaluate stability, susceptibility to rockfall was determined using a theoretical–practical procedure, and the safety factor was calculated using the Morgenstern–Price method. The analysis of the geomechanical classifications yielded a low stability value of the slope, which was in accordance with the high susceptibility to rockfall and with the low safety factor. Based on these results, we recommend the application of systematic bolt and shotcrete for stabilization.
