Understanding the retreat of the Jurassic Cantabrian coast (N. Spain): comprehensive monitoring and 4D evolution model of the Tazones Lighthouse landslide

Forecasting coastal dynamics and sea cliff retreat under different sea level rise scenarios requires a good understanding of the conditioning factors and their relative contribution to cliff stability. The so-called Jurassic Cantabrian Coast extends along 76 km of the coastline of the Asturias region (N Spain) and is well-known worldwide due to its paleontological heritage, in particular the presence of dinosaur remains and footprints. The abundance of stratigraphic, paleontological and tectonic studies contrasts with the scarcity of studies focused on the stability of this rocky coastline where cliffs predominate, sometimes exceeding 120 m in height. In fact, evidence of current and recent instability processes can be observed along the entire coastline. In this regard, continuous monitoring is crucial to understand ongoing instabilities in rocky coastlines, as in these settings some instabilities might initiate as slow movements that induce subtle topographic changes whose detection from either satellite or aerial imagery is problematic due to the spatial and temporal resolutions.This research is part of 1) the “COSINES” Project [CGL2017-83909-R], Call 2017 for RETOS Projects funded by the Spanish Economy, Industry and Competitiveness Ministry-Ministerio de Economía, Industria y Competitividad (MINECO), the Spanish Research Agency-Agencia Estatal de Investigación (AEI) and the European Regional Development Found (FEDER) and 2) the GEOCANCOSTA research group, supported by the Asturian Regional Government (Spain) [grant number GRUPIN-IDI-2018-184]

The Asturian Miminig company, la primera gran siderúrgica moderna española.: Construcción y puesta en funcionamiento de la factoría y el alto horno de Mieres

In the early forties of the nineteenth century, when the large steelworks projects of the Real Compañía Asturiana de Minas and the Compagnie de mines d’Espagne had already been discarded, a group of French and English capitalists, supported by Asturian personalities, recorded a number of mining concessions in the municipalities of Tudela and Mieres with the intention of establishing a miner and metallurgical company. After a first failed attempt in 1842 to create a company based in London under the name The Asturian Coal and Iron Company, two years later they succeeded in founding The Asturian Mining Company. In the beginning, its actions were submitted by investors to strong speculative movements on the London Stock Exchange. However, the company built in Mieres (Asturias) the first steelworks in Spain that used coke as fuel in its blast furnace. In this paper we reveal the process, hitherto unknown, of construction of the factory; the British subcontractor that provided the necessary know-how for the construction of the blast furnace and the events that occurred with the ignition. We also describe the steam engines installed and the other facilities that were built: puddling oven, drop hammers, workshops and so on.A principios de los años cuarenta del siglo XIX, cuando los grandes proyectos siderúrgicos de la Real Compañía Asturiana de Minas y de la Compagnie de mines d’Espagne habían sido ya orillados, un grupo de capitalistas franceses, belgas e ingleses, apoyados por personalidades asturianas, registraron un buen número de concesiones mineras en los concejos de Tudela y Mieres con la intención de constituir una gran empresa minero-metalúrgica. Tras un primer intento fallido de crear en 1842 una empresa con sede en Londres bajo la denominación de The Asturian Coal and Iron Company, dos años después consiguieron fundar la sociedad anónima The Asturian Mining Company. En los primeros momentos de su existencia, las acciones fueron sometidas por los inversores a fuertes movimientos especulativos en la bolsa londinense. No obstante, la compañía llegó a construir en Mieres (Asturias) la primera factoría siderúrgica que utilizó coque en España. En el presente trabajo desvelamos el proceso, hasta ahora desconocido, de construcción de la fábrica; la empresa subcontratista británica que aportó el conocimiento tecnológico necesario para el levantamiento del alto horno y las vicisitudes que ocurrieron con su encendido. También describimos las máquinas de vapor que se pusieron en funcionamiento y las demás instalaciones que se construyeron: hornos de pudelaje, martinete, talleres, etc

El dibujo de paisaje en la ingeniería: la colección de vistas de la Comisión del Mapa Geológico de España (1850-1853)

Resumen y palabras claves en español, francés e inglésDesde el Renacimiento, el dibujo de paisaje adquirió interés para el conocimiento del territorio. Siguiendo el modelo francés, a comienzos del siglo xix se implantó como asignatura en las enseñanzas de ingeniería en España. Este artículo da cuenta de la inédita colección de vistas del paisaje elaborada entre 1850 y 1853 por la Comisión del Mapa Geológico con fines geodésicos.Universidad de Oviedo, EspañaInstituto Geológico y Minero de España, Españ

Using Remote Sensing Methods to Study Active Geomorphologic Processes on Cantabrian Coastal Cliffs

Gravitational processes on inaccessible cliffs, especially in coastal areas, are difficult to study in detail with only in situ techniques. This difficulty can be overcome by the complementary application of remote sensing methods. This work focuses on an active complex landslide affecting the slope of the Tazones Lighthouse (Cantabrian coast, North Iberian Peninsula), which has been monitored since June 2018. The aim of this research is to establish a conceptual model of the internal structure of the slope. A remote multitechnique approach was applied, including landscape deformation analysis from photogrammetric surveys, ground motion detection applying A-DInSAR techniques and Sentinel-1 satellite data, and electrical resistivity tomography. The obtained results showed the great potential of some of the remote techniques, such as UAV photogrammetry and electrical tomography, and the ineffectiveness of others, such as A-DInSAR, which failed to provide adequate results due to the profuse vegetation. This work made it possible to establish a geological model of the functioning of the slope of the Tazones Lighthouse and to deduce the surface extent of the destabilized mass (70,750 m2), the rupture surface shape (stepped), its in-depth extent (10–50 m), the volume of materials involved (~3,550,000 m3) and the type of landslide (complex including a predominant translational slide). The combination of field and remote sensing data significantly increased the possibility of reaching a comprehensive geological interpretation of landslides on rocky coasts
