Cover Story: The ancient Albojaira (in Arab: Al Bujaira) Lake within the Almanzora Canyon disappeared during the 1863 Huércal-Overa Earthquake (SE Spain), suggesting an intensity of VIII-IX ESI-07. The lake was located within an abandoned meander of the Almanzora River (terrace +20 m) at the site named Los Oribes. The lake was emptied during the earthquake because of large ground-cracking in the ancient lake ground. Only the three permanent water bodies known as the “Ojos de Mar” (Sea Eyes) prevailed, but also emptied during subsequent seismic series. Ground photo kindly provided by Dr. Martin Stokes (University of Plymouth). View this paper

The stability of rock slopes is often guided significantly by the structural geology of the rocks composing the slope. In this work, we analysed the influences of structural characteristics, and of their seismic responses, on large and deep-seated ro...

  • Gianfranco Urciuoli

Proper soil water retention curves (SWRCs) are necessary for a fair analysis of groundwater flow in unsaturated slopes. The question is whether hydraulic parameters operating in situ can be reliably determined from laboratory tests or physical protot...

Reconstruction after an earthquake is often seen as a material issue, which concerns “objects” such as houses, roofs, and streets. This point of view is supported by the mass media showing the work progress in the disaster areas, especial...
