Scientists find evidence that structural damage to the Alhambra is due to seismic activity

14.04.2004


The Granada Basin, home to the Alhambra, is located in one of the most seismically active zones in the Iberian Peninsula. Historical evidence shows that the last major earthquake occurred there in 1431. New evidence indicates, however, that the topographical features of the area surrounding the Alhambra reflect recent and recurrent, though moderate, seismic activity. The research is published this week in Journal of Quaternary Science.



The Alhambra, one of the most visited monuments in Europe and a world heritage site, was the focus of research carried out by scientists in Granada. They studied the cracks and other damage to the structure of the monument, small-scale faults affecting the substratum, topographic steps, and seismic focal mechanisms, which evidence seismic activity produced by normal faults nearby the Alhambra.

Although the structural damage displayed by the Alhambra is far from significant, the cracks were able to be related with underlying faults that are possibly seismically active. Some of the cracks showed a geometrical continuity with fault planes in the underlying conglomerates, while collapsed segments of a wall surrounding the Alhambra coincide with underlying faults that cut Quaternary soil levels. Thus the structural damage and topographical steps in the neighbourhood of the Alhambra are shown to be caused by repeated earthquakes over the last 800 ka.


Based on their observations of the Alhambra Formation and the surrounding geomorphological evidence, the researchers have described the seismic risk associated with the faults of the Alhambra and surrounding areas as moderate.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
