“…The intrinsic value was evaluated through representativeness, rarity, integrity, observability, scientific knowledge, type locality and diversity. The entire inventory consists of 45 geosites, 30 of which are of geomorphological interest (Galindo et al, 2019(Galindo et al, , 2022. In order to test the hypothesis, related to the existence of implicit magnitude drivers, we made a complete cartographic collection of the similar elements of each geosite in the whole territory, accurately calculated their dimensions and ranked them.…”

Since the 1990s, an international consensus has been emerging with respect to the methods used to identify and assess geosites. These conventional methodologies generally differentiate between the intrinsic or scientific-natural dimension and the social dimension in the potential value of the geological elements. The aim of this article is to analyse the possible existence of other concepts that may underlie these criteria and that could be operating as evaluation parameters even though they are not explicitly and formally described as such in the published studies. An exhaustive analysis of articles on geosite inventories published in Science Citation Index journals in the last 15 years revealed a systematic reference to conceptions of magnitude (in the sense of degree of development and physical prominence) in geosite descriptions around the world, and in particular with respect to sites of geomorphological interest. To contrast this indication, we subjected the geosites inventory of Lanzarote (Canary Islands, Spain) to a Magnitude Rule hypothesis. This inventory is part of the Spanish Geosites Inventory (IELIG, for its initials in Spanish), which was carried out using conventional assessment procedures. Applying this rule, according to which each geosite is the most prominent example of its typology within the reference geological domain, we obtained an almost complete match. That is, geomorphological sites that were selected, a priori, according to intrinsic and social dimension were also (or one could even say ‘actually’) selected, implicitly, on the predominant basis of magnitude. This paper discusses why and how the magnitude parameter may be playing a key role as a subliminal non-explicit driver in the evaluation of geosite relevance, and how this finding may open new perspectives and bring methodological advantages in the inventory of geological heritage.

“…The techniques for geoheritage identification and valuation procedures, that were born as a scientific discipline in the 1970s, aims at providing foundations for the environmental protection of relevant geological sites and landscapes, that is, for geoconservation (e.g., Bostick et al, 1975;Duque et al, 1979;Elizaga et al, 1980). Due to their remarkable geological features and their scientific and social attractiveness, the are many precedents of geoheritage studies in volcanic territories (e.g., Galindo et al, 2019;Guilbaud et al, 2021;Megerle, 2020;Németh et al, 2017;R ożycka & Migo n, 2018;Szepesi et al, 2017). In particular, the Canary Islands, which constitute one of the most prominent oceanic volcanic chains in the world, have been declared as a geological framework of international relevance (García- Cortés, 2008; García-Cortés et al, 2001) and have already been the subject of several works of geosites selection and assessment (e.g., Becerra-Ramírez et al, 2020;D oniz-Páez et al, 2011;D oniz-Páez et al, 2020;Galindo et al, 2019Galindo et al, , 2022.…”

For their scientific value, most of the recent monogenic eruptions on the island of La Palma have been included in the Spanish Geosites Inventory (IELIG project, IGME-CSIC, http://info.igme.es/ielig/), within the regional framework of 'Historical and Prehistoric Volcanism' (Vegas et al, 2019).…”

A geoheritage valuation to prevent environmental degradation of a new volcanic landscape in the Canary Islands

On 19 September 2021, a new monogenetic volcano (Tajogaite) erupted on the Island of La Palma (Canary Islands, Spain). After 85 days of Strombolian style eruption, with emissions of volcanic material, a pyroclastic cone 200 m high and 800 m in its basal diameter was formed. Successive lava flows descended the western slopes and reached the Atlantic Ocean on 29 September. On descending the coastal cliffs and entering the sea, the lava flows formed two lava deltas on the submarine island shelf, backed by fossilized coastal cliffs. This geological event has raised a new challenge: the environmental conservation of new volcanic landscapes in island territories with high anthropogenic pressure on land uses. This work uses comparative and numerical methods in geoheritage to support their conservation from a scientific basis. In a first phase, a cartographic inventory was made of all the volcanic formations similar to the new volcano in the geological framework of the Canary Islands. In a second phase, their representativeness (A), rarity (R), diversity (D), integrity (I), and observability (O) were quantitatively measured by means of dimensional estimators. The results obtained show that the new volcano presents a geological value of the first order in the context of the Canary Islands, which is one of the most prominent oceanic archipelago worldwide. Its value is based above all on its high conservation state with respect to the similar volcanoes in the Canary Islands. The high mismatch found between the intrinsic geological value and the environmental protection of this area, justifies the development and application of urgent basic guidelines for its protection, as well as the promotion of geotourism as opposed to alternative land uses.
