Con un planteamiento pertinente y un enfoque institucionalmente neutral e independiente, la obra agrupa más de medio centenar de...

The urban area of Albuñuelas, a small town located to the south of Granada (S Spain), has been developed in terrain affected by a large-scale rotational landslide with very slow rate of movement. Despite this situation, the internal structure of the landslide and how it has evolved to its present state has not been analyzed in depth up to now. In t...

In this work, a method for the fast evaluation of seismically-induced landslides is applied at regional scale in the Granada Basin (southern Spain). The methodology is based on the concept of rigid block but takes into account the variability in input data (geotechnical properties, failure depth and saturation state of the materials) through the us...

The project is interdisciplinary in nature, combining innovative techniques from both the natural sciences and the social sciences to address the problem: how could society become more resilient to the risks and natural hazards associated with volcanoes. It focuses on volcanoes that have not erupted in recent times, are considered dormant, but have...

An online survey was released in collaboration with the Nicaraguan Institute for Territorial Studies (INETER) and the National Autonomous University of Nicaragua (UNAN-Managua). Preliminary results from a sub-sample of community members from Managua N=204 (111 women, M age=30.68; SD=13.39) are presented. Participants indicated their perception atti...

The reactivation of very large landslides may cause severe damage to society. Its prevention and management requires detailed information on the geometry and structure of these landslides, but the use of standard techniques (boreholes) may be prohibitive from an economic point of view. To overcome these difficulties, geophysical techniques are of s...

This paper analyses the seismic vulnerability of various rammed earth medieval fortifications situated in Southeastern Spain, where seismic events with intensity over VII have taken place in the last millennium, using the vulnerability index method. This method begins with the choice of a certain initial value, V0, of the vulnerability index, which...

In this study, an inventory of landslides induced by the 2011 Lorca earthquake (Mw 5.1) has been used in order to develop a new procedure to obtain objective logic-tree weights for a probabilistic earthquake-induced landslide hazard analysis. The 2011 Lorca earthquake triggered more than 250 landslides, mainly of disrupted type. The logic-tree was...

Land-use decisions in relation to seismic-induced landslide hazard are usually made through the preparation of hazard maps. The rigid-block method is probably the most used for this purpose. Under this method, Newmark displacement is computed for each slope unit and this displacement is used as a guide for establishing categories of hazard. At pres...

Newmark displacement estimation is generally computed using empirical models. These models are estimated from large datasets that mainly comprise moderate-to-high magnitude events (Mw > 6.0). In this work, we study the performance of several of these models to study moderate-to-low magnitude scenarios. For this purpose, data from the Betic Cordille...

Land-use planning in regard of earthquake-triggered landslides is usually implemented by means of the production of hazard maps. The well-known Newmark rigid block methodology is the most frequent used approach for this purpose. In this method, slope stability is evaluated by the estimation of the Newmark displacement, which is used to set differen...

Medieval defensive earthen architecture is typically represented by big and well maintained defensive walls, lookout towers or castles despite mostly represented by remains of tower walls or defensive walls. While studies on natural hazards have been carried out concerning these castles or lookout towers, there are no studies on defensive walls. Bo...

The January 25, 2016, Mw 6.3 Alborán Sea earthquake shook the autonomous city of Melilla (Spain) with a macro-seismic intensity of VI (EMS-98). In spite of this low intensity, significant non-structural damages were reported, whose cost was estimated in more than 13 million euros. The damages were concentrated in the modernist district, which is co...

On February 23, 2015, an earthquake of magnitude Mw 4.7 (Imax = V, scale EMS) struck the center of the Spain, triggering dozens of instabilities in taluses and natural slopes of an area characterized by low relief. These instabilities were characterized by: (1) very small size, most of them with volumes lower than 1 m³, and (2) to occur in rock mas...

The H/V technique is used throughout this research to characterize the soil column at different locations of the metropolitan area of Málaga (Southern Spain). This region stands as a good example of a continuously growing zone, mostly developed on soft alluvial sediments, with moderate to low seismicity. The H/V analysis of the noise measurements r...

The interaction between seismic waves and slopes is an important topic to provide reliable scenarios for earthquake-(re)triggered landslides. The physical properties of seismic waves as well as slope topography and geology can significantly modify the local seismic response, influencing landslide triggering. A novel approach is here applied to two...

Geochemical and geophysical techniques have been applied to investigate the potential environmental impact of the abandoned La Aquisgrana mine tailings, one of the most important sulfide-bearing tailings ponds of the Linares-La Carolina mining district (Spain). The geometry of the pile has been defined through geological field work and electrical r...

Most of the Spanish cultural heritage is exposed to natural hazards. This fact is opposed to a sustainable development, which is the cultural heritage base, because its goal is to be passed down to future generations (Andalusian Cultural Heritage Law 2007). The impact of natural hazards on the Spanish cultural heritage has been checked over the Lor...

The Diezma landslide (Southern Spain) occurred on March 18 of 2001 after a heavy rainfall period, interrupting an important motorway. Landslide involves a heterogeneous soil laying on a metamorphic substratum (shale). A geological model has been made using 34 boreholes drilled between 1998 and 2012 in this area. As it results from this model, the l...

The La Carolina district, which is located in Jaen (Southern Spain), has experienced important mining activity for centuries. These long-standing mining activities, which have been associated with the presence of a philonian network of metallic sulfides, have generated vast accumulations of mine wastes—primarily tailings impoundments—that contain h...

A novel unconventional pseudostatic analysis is proposed here to infer on the sensitivity of a landslide to earthquakes characterized by different physical properties. Several sine waves with different amplitudes, frequencies and phases were applied to the landslide mass assuming limit equilibrium conditions. The unconventional approach was used fo...

The socioeconomic losses in Spain and Italy due to natural hazards are considerable. Most of them are related to a policy which is not sufficiently based on prevention. Spatial and town plannings are the most efficient and economic tools for natural hazards prevention, through prohibitions or restrictions. In Spain, the use of natural hazards maps,...

According to the Ministry of Internal Affairs, in the 1990–2012 period, there have been 57 deaths in Spain due to mass movements. The economic losses were estimated at about €180 million each year. Some of these losses have been related to violating the laws and/or the lack of risk-focused land use planning. In accordance with the provisions set ou...

Es un hecho ampliamente asumido que la gestión del agua potable suele ser un "asunto de mujeres" en relación a que el acceso al recurso hídrico es una necesidad cotidiana de las mujeres en sus roles de cuidado y mantenimiento del entorno y el hogar (Murdialgay, 2012), y son éstas las que más resienten su carencia porque son las que realizan las tar...

La ocurrencia de inestabilidades de ladera inducidas por terremotos es conocida en España y Portugal desde épocas remotas. Durante las últimas décadas, varios grupos de investigación han realizado estudios al respecto que han permitido recopilar información sobre este fenómeno. En este trabajo se realiza una revisión de las aportaciones realizadas...

Granada and its metropolitan area lie on the eastern edge of a basin where the foothills rise into the adjacent Sierra Nevada (3,482 m). On the west the valley is bordered by several faulted, Quaternary-age alluvial fans and by dissected terraces of the Genil River. Landscape evolution from about Tortonian to Pleisto-cene time is reflected by relic...

Earthquakes often induce landslides. During the last decade, several research groups have collected information about this effect in relation with earthquakes felt in Spain, both historic and recent times. In this work, a review of data collected to date is done, describing the typology of induced landslides recognized, their relative abundance dep...

An earthflow near Cenes de la Vega (southern Spain) was first observed after a heavy rain in January 2010 in an area where a spring had existed. Initially, the landslide affected only the lower part of the slope. Displaced materials accumulated over terraces and the river course, damming it. A year later, a new rainy period reactivated (or increase...

Earthquakes may induce landslides at large distances from the epicentral area. In the last two decades, there have been many studies of this phenomenon to determine the causes that contribute to the occurrence of landslides at very long distances from earthquake epicenter. In this study, which is based on previously published works, a worldwide dat...
