Volcanoes in motion

[EN] We explain the geological history of the island of El Hierro through a collection of eight panels. How the Canary Islands were formed and evolved is contextualized, and we introduce the birth of El Hierro. Next, we observe the landscapes of El Hierro as a response to macro-scale, such as giant landslides and rifts, and micro-scale phenomena (cones, lavas, and shore platforms). The last eruption of the island that gave rise to the Tagoro submarine volcano is also exposed. Finally, we present how the Herreños have adapted to the territory, knowing how to take advantage of its scarce water resources and adapt their way of life to the volcanic landscape, achieving that the entire island was declared in 2000 a UNESCO World Biosphere Reserve and Geopark in 2015.[ES] A través de una colección de ocho paneles se explica la historia geológica de la isla de El Hierro. Se contextualiza cómo se formaron y evolucionaron las Islas Canarias y se introduce el nacimiento de El Hierro. A continuación, se observan los paisajes herreños como respuesta a fenómenos de macroescala, como los deslizamientos gigantes y las dorsales (rifts), y microescala (conos, lavas e islas bajas). Se expone la última erupción de la isla que dio lugar al volcán submarino Tagoro. Finalmente, se presenta cómo los herreños se han adaptado al territorio, sabiendo aprovechar sus escasos recursos hídricos y adaptando su modo de vida al paisaje volcánico que le rodea, consiguiendo que la isla al completo haya sido declarada por la UNESCO Reserva Mundial de la Biosfera en el año 2000 y Geoparque en el año 2015.Project LAJIAL (ref.

Volcanoes in motion: El Hierro and La Palma (Canary Islands)

Ten informative panels were designed to organize an exhibition of the LAJIAL project results about the recent volcanism of El Hierro Island and the 2021 eruption in La Palma Island. The format was self-rolling panels (roll-ups) 1 m wide by 2 m high, easily transportable, and highly protective. This exhibition was entitled 'Volcanoes in motion: El Hierro and La Palma' and allows us to understand that the volcanic phenomenon is very dynamic and capable of quickly changing the forms of relief, the water network, or the land use. The presentation in all these panels always keeps the same content: an upper strip including the titles of the exhibition, the thematic block, and the panel, as well as its numbering and logos of the promoting entities; a central part with much visual information in the form of maps, figures and photos accompanied by concise and easy-to-read texts; and a lower strip with the credits of the authors and logos of their institutions. The first block of panels, 'A sea of volcanoes', deals with the generation of intraplate volcanic islands, with the example of the Canary Islands (Panel 1: The Canary Islands, that is how it all began) and the geological evolution of the island of El Hierro (Panel 2: And El Hierro was born). The second block, 'Volcanic landscapes of El Hierro', focuses on geological structures on a large scale (Panel 3: Megastructures) and a small scale (Panel 4: Structures on the ground). The third block, 'Explore your volcanic paradise', pays homage to the geological maps and the last eruption on El Hierro island. Panel 5: Walking among volcanoes shows the Gorona del Lajial eruption, a true paradise of volcanic structures but a geological puzzle solved within the framework of the LAJIAL project. Panel 6: 'The last volcano' is dedicated to the eruption of the Tagoro submarine volcano. The fourth block, 'Living among volcanoes', focuses on the islander's adaptation to the volcanic territory through the rational exploitation of groundwater (Panel 7: Water on El Hierro), volcanic materials as construction elements, or the figure of the UNESCO Geopark of El Hierro (Panel 8: What the land tells us), which brings together the geology of the island with its inhabitants, promoting the sustainable development, its agricultural techniques or knowledge of its archaeological remains. The last block of two panels, 'La Palma: the pretty island' is devoted to the geological evolution of La Palma island (Panel 9: And La Palma was born) and the 2021 eruption of Tajogaite volcano (Panel 10: The eruption of 2021) that represent the last volcanic activity in the archipelago.Project LAJIAL, Grant PGC2018-101027-B-I00 funded by MCIN/AEI/10.13039/ 501100011033 and by "ERDF A way of making Europe", by the "European Union"PhD Grant 2021 FISDU 00347, Departament de Recerca i Universitats, Generalitat de CatalunyaResearch Consolidated Group GEOVOL (Universidad de Las Palmas de Gran Canaria)Research Consolidated Group GEOPAM (Generalitat de Catalunya, 2017 SGR 1494)Peer reviewe
