Assessing earthquake effects on archaeological sites using photogrammetry and 3D model analysis
No full textThis paper evaluates the application of photogrammetric recording to seismically-affected archaeological sites from the moment of on-site data acquisition through to the analysis of the resulting 3D model. This methodology facilitates (i) rapid but accurate recording of seismically-damaged archaeological contexts, (ii) three-dimensional reconstructions, (iii) the documentation of archeological features (e.g. plans, sections, elevations), and (iv) the extraction of additional information and data for archaeoseismological analysis (DEMs, for instance). Not only is greater detail observed using these methods but it can also be quantified at a distance from the target site, thereby extending the researcher's time in the field. 3D photogrammetry and modelling also reduce the risk that small but significant features such as seismic fractures and deformations are overlooked. This paper draws on evidence from two case studies of the EU-funded ArMedEa project (Archaeology of Medieval Earthquakes in Europe, 1000-1550 AD), namely the Islamic fortified village of El Castillejo (Guajar Faragüit, Granada, Spain) and the crusader castle of Saranda Kolones (Paphos, Cyprus)
Researching Natural Disasters in the Later Middle Ages

A generic toolkit for the visualization of archaeological features on airborne LiDAR elevation data
No full textA range of techniques have become established for the visualization and analysis of airborne LiDAR elevation data within the field of archaeology. In this paper we discuss the visualization of test data representing archaeological features in a variety of terrains using a suite of techniques, all available through generic geographical information system or image processing software. These comprise elevation shading using constrained colour ramps, slope analysis, hill-shading, principal component analysis of multi-azimuth hill-shading, local relief models and solar insolation modelling. The strengths and weaknesses of each technique are discussed and a generic toolkit, suited to the visualization of airborne LiDAR data for archaeological purposes, is presented. © 2011 John Wiley & Sons, Ltd
Exploring representativeness and reliability for late medieval earthquakes in Europe
No full textSeismic catalogues of past earthquakes have compiled a substantial amount of information about historical seismicity for Europe and the Mediterranean. Using two of the most recent European seismic databases (AHEAD and EMEC), this paper employs GIS spatial analysis (kernel density estimation) to explore the representativeness and reliability of data captured for late medieval earthquakes. We identify those regions where the occurrence of earthquakes is significantly higher or lower than expected values and investigate possible reasons for these discrepancies. The nature of the seismic events themselves, the methodology employed during catalogue compilation and the availability of medieval written records are all briefly explored
Rituals of resilience. The interpretative archaeology of post-seismic recovery in medieval Europe
No full textThroughout the later Middle Ages (AD 1000–1500), seismic catastrophes in Europe led to considerable losses of life as well as inevitable structural, infrastructural and economic damage. This paper provides an overview of the archaeological evidence for the reactions of medieval people to seismic disasters—tackling, in particular, the role of interpretation, belief and ideology in post-event counter-measures which can be glimpsed through the archaeological record. Three specific aspects are considered in detail: the rescue of earthquake victims in the ‘golden hours’ after a seismic disaster, the interpretation of the seismic event in the adoption of mitigative responses, and the use of symbols in pre- disaster protective technology. Ultimately, the paper reflects on how the archaeologist might analyse archaeological sites affected by natural disasters, emphasising the adop- tion of a more critical, interpretative and contextual approach in order to investigate relevant cognitive elements which contribute to the shaping of so-called local ‘seismic cultures
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
