Almost exactly half a century after the eruption of Teneguía Volcano on La Palma (26 October to 28 November 1971), new occurred island and lasted for 85 days from 19 September until 13 December 2021. This opened volcanic vent complex western flank Cumbre Vieja rift zone, N‐S elongated polygenetic ridge that has developed over last c . 125 ka. The is volcanically active region most one Canary Islands, hosting all historically recorded eruptive events in archipelago. 2021 seen no direct loss...

222Rn has been detected in 28 groundwater samples from the northeast of Gran Canaria (Canary Islands, Spain) utilizing a closed loop system consisting an AlphaGUARD monitor that measures radon activity concentration air by means ionization chamber, and AquaKIT set transfers dissolved water to within circuit. Radon studied varies between 0.3 76.9 Bq/L. Spanish radiological protection regulations limit for drinking 100 Bq/L, therefore values obtained all analyzed are below this threshold. The...
Abstract Aim Long‐term ecological data provide a stepped frame of island ecosystem transformation after successive waves human colonization, essential to determine conservation and management baselines. However, the timing impact initial settlement on many islands is still poorly known. Here, we report analyses from 4800‐year sedimentary sequence Gran Canaria (Canary Islands), with goal disentangling forest responses natural fire early pressure island. Location La Calderilla, volcanic maar...
Abstract Previous published data, combined with our results of 13 new radiocarbon ages and extensive geological fieldwork, indicate that during the past 11 ka 24 monogenetic basaltic eruptions occurred in north sector Gran Canaria. These can be grouped into three periods eruptive activity: 1900–3200 14 C a BP; 5700–6000 an older period represented by only one eruption, El Draguillo, dated at 10 610 ± 190 BP. Archaeological studies have shown more recent affected prehistoric human settlements...
La erupción del Complejo Volcánico Cerro Blanco en el sur de la Puna, noroeste Argentina (4410–4150 a BP) se investigó para obtener nueva información sobre estratigrafía, geomorfología, volcanología física, dataciones por radiocarbono, petrografía y geoquímica. caracterización los productos relación evolución caldera permitió estimar distribución depósitos ceniza fase paroxísmica Plineana erupción. Estos novedosos resultados evidencian una gran explosiva riolítica que generó cineríticos un...

Abstract: A complete framework of chronostratigraphic, petrographic, geochemical and thermobarometric data allows a reinterpretation the evolution Plio-Quaternary volcanism in Gran Canaria. Bulk-rock mineral chemistry has been used to define P – T crystallization paths, based on clinopyroxene–melt thermobarometry. Mafic magmas mainly crystallized at mantle depths (17–22 km) with secondary fractionation crustal levels (1.5–8.0 km), suggesting multistage magma ascent. Crystallization evolved...
El Hierro, the youngest of Canary Islands (Spain), is no stranger to hazards associated with volcanic activity or efforts minimize effects these on local communities. As early as 1793, administrative records Hierro indicate that a swarm earthquakes was felt by locals; fearing greater catastrophe, first evacuation plan an entire island in history Canaries prepared. The 1793 eruption probably submarine appreciable consequences other than were [ Carracedo , 2008]; over next roughly 215 years...
This work presents the first detailed map of Holocene eruptions Gran Canaria (Canary Islands, Spain). It provides complete and information for all 24 Canaria, improving knowledge this recent volcanism assessment volcanic hazards on island. is a synthesis collated interpreted field data topographic maps. We have integrated obtained from: (1) geological surveys, (2) morphometric analysis eruptive deposits, (3) high-resolution digital elevation models, (4) aerial photographs.
In recent months the media have drawn attention to Cape Verde archipelago, with particular focus on island of Fogo, only presently active and an eruption that began 23 November 2014, finally ceasing 7 February 2015. The Monte Amarelo conical shield forms most 476 km 2 almost circular Fogo. After attaining a critical elevation about 3500 m, volcano was decapitated by giant landslide formed caldera‐like depression (Cha das Caldeiras), which subsequently partially filled basaltic nested...
Marine and subaerial erosion of volcanic ocean islands form coastal cliffs shore platforms, particularly during stable sea levels. Posterosional lava flows can spill over these fill the leading to progradation deltas. This work aims analyze this rocky coast setting at island scale assess constructional erosive degradational effects on one edifice. El Hierro Island, Canary Islands, exemplifies a with an active sea-cliff profile, reflecting its early evolutionary stage as young no fringing...
The classification, assessment, and estimation of the atmospheric corrosivity are fixed by ISO 9223 standard. Its recent second edition introduced a new category for extreme environments CX, defined mathematical models that contain dose–response functions normative estimations. It is shown here application standard to archipelagic subtropical areas exhibits major shortcomings. Firstly, corrosion rates zinc copper exceed range employed define CX category. Secondly, would require be redefined...
