To influence public awareness of seismic risk in Spain and how policy-makers perceive such risk and to improve preventive efforts (from hazard maps and building codes to legislation), this work (1) synthesizes the loss and damage experienced in historical and modern times in Spain, (2) explores empirical loss scenarios by applying the USGS PAGER (P...

Below the central nave of the Gothic Cathedral of Palencia (14th to 16th centuries) lies the Crypt of San Antolín, which represents the remains of a Visigothic building from the mid-7th century. The crypt itself has suffered recurrent episodes of flooding over the centuries. However, the latest flooding, which began in mid-2021 and ended in mid-202...
Resumen: El presente trabajo analiza la tectónica cuaternaria del Valle del Tajuña (Madrid) haciendo hincapié en el ensamblaje geomorfológico de superposición/solapamiento de los niveles de terraza más modernos (+8, +10 y +12m), y las características de los Escarpes en yesos (fallas) de unos 60 m de altura que los enmarcan. El análisis se completa...
El presente trabajo resume el conjunto de nuevas investigaciones geológicas y arqueológicas que certifican la ocurrencia de un potente evento terremoto-tsunami que devastó la antigua ciudad romana de Baelo Claudia (Estrecho de Gibraltar) en la segunda mitad del siglo IV d.C. Aparte de las importantes deformaciones cosísmicas documentadas en forma d...
The renaissance botanical garden of ‘El Bosque’ in Béjar (Salamanca, Spain) presents a pond bounded by a dam in its western part. The latter is formed by two masonry walls interconnected by buttresses. Cubic spaces in between are filled with a variable grain‐size material (silty sand) that allows limited water flow. In recent years the southern par...
The “Caliphal City of Medina Azahara” was built in 936–937 CE or 940–941 CE (depending on the source) by the first Caliph of al-Andalus Abd al-Rahman III, being recently inscribed (2018) on the UNESCO World Heritage List. The abandonment and destruction of the city have been traditionally related to the civil war (“fitna”) that started between 1009...
We report on the tsunami deposits burying the coastal Roman remains of the Baelo Claudia archeologic site and its environs up to ca. +8 m above the sea-level. New data on 2D ERT profiles (Electric Resistivity Tomography) of the lagoonal zone near the eastern necropolis adjacent to the city walls as well as new sedimentologic insights on the paleots...
In this work, two earthquakes are compared that occurred in the same area of Ademuz (Valencia): the Ademuz earthquake of June 7, 1656 (EMS VIII), and the earthquake of March 10, 2006 of magnitude Mw 4.3 (EMS V-VI). The geological effects of the 1656 earthquake have been evaluated applying the ESI-07 intensity scale, obtaining a maximum intensity of...
We have applied archaeoseismological techniques to evaluate the historical information about the earthquake/hurricane that occurred in Cordoba, on 21 st September 1589 (Southern Spain). We have estimated the Earthquake Archaeological Effects (EAEs) and the macroseimic earthquake environmental scale ESI07 to destruction patterns of buildings and chu...
Este trabajo presenta nuevos mapas de anomalía magnética y gravimétrica absoluta (Bouguer) del yacimiento polimetálico del Cerro de Almadenes (Otero de Herreros, Segovia). Los datos han sido adquiridos y procesados con equipamiento y técnicas modernas (eliminando todas las posibles fuentes de ruido), y los mapas obtenidos se han comparado con los m...

this work offers methods for the quantification of the deformation in Archaeoseismological scenarios using drone-based high-resolution 3D models.
Abstract
This study deals with the morphometric characterization and quantification of earthquake damage in the ancient Roman city of Baelo Claudia in South Spain (Gibraltar Arc) by...
In the last two decades, as the importance of soil has been recognized as a key component of any ecosystem, there has been an increased global demand to establish criteria for determining soil quality and to develop quantitative indices that can be used to classify and compare that quality in different places. The preliminary estimation of the attr...
In recent years, the interest of institutions in land use has increased, creating the need to determine the changes in use through spatial-temporal and statistical analysis. This study analyzes the changes over the last 40 years, based on a cartography of landscape units obtained from the study of geo-environmental parameters in the Jerte Valley (S...
Soil erosion is one of the most important environmental problems of the moment, especially in areas affected by wildfires. In this paper, we study pre-fire and post-fire erosion using remote sensing techniques with Sentinel-2 satellite images and LiDAR. The Normalized Burn Ratio is used to determine the areas affected by the fire that occurred on 1...

The lack of urban sustainability is a widespread deficiency in urban agglomerations. To achieve adequate land use, we present a methodology that allows for: 1) the identification of the impacts caused by urban expansion since 1956 to the present in Salamanca (Spain); and 2) the promotion of a more sustainable future in urban development. A multi-te...
El Radar de Apertura Sintética (SAR) es una herramienta muy potente para el control de la superficie ocupada por agua en la superficie terrestre, y así cuantificar las consecuencias generadas por los posibles episodios de sequías e inundaciones. En el presente trabajo se calcula la extensión de la lámina de agua del embalse Jerte-Plasencia mediante...

La erosión es un problema medioambiental de relevancia, reconocido mundialmente y con una legislación específica de carácter estricto, en constante revisión. A nivel nacional según datos del Ministerio de Agricultura y Pesca, Alimentación y Medio Ambiente (MAPAMA) el 12.6 % de la superficie estatal está afectada por procesos erosivos extremos o muy...
Erosion and the production of sediments effect the siltation of reservoirs and create large environmental problems. This work calculates the volume of sediments caused by erosion in a hydrological basin using the Revised Universal Soil Loss Equation 2 (USLE–RUSLE2), applying, or not, the sediment delivery ratio, and is compared with the volume of s...
Wildfire is a major threat to the environment, and this threat is aggravated by different climatic and socioeconomic factors. The availability of detailed, reliable mapping and periodic and immediate updates makes wildfire prevention and extinction work more effective. An analyst protocol has been generated that allows the precise updating of high-...
