UGR professor Jesús Galindo Zaldivar, together to the Spanish Geological and Mining Institute (IGME –Ministry of Education and Science) have carried out a study of the variables suffered by the earth’s crust in the area of Almeria.
Through the geological observation of the field and the carrying out of geophysical prospecting, which determine the deep structure of the Campo de Dalías and the Campo de Níjar, it has been possible to establish the relationship between the tectonic structures observed in the surface and in depth. In addition, they have analysed the seismic activity of the area registered by the Andalusian Seismic Network, managed by the Andalusian Institute of Geophysics of the University of Granada (Universidad de Granada [http://www.ugr.es]).
Applications of the study
The results of the research work have allowed to identify the state of the active structures with seismic risk for the population of the area, besides involving a significant advance in the knowledge of geometry of the geological formations which form the aquifers of the region, necessary to get to know how to exploit and manage them correctly in a strongly agricultural area. Thanks to these research works it has been possible to establish a recent tectonic evolution for the south east of the Bética Mountain Range, with lifting over the sea level of marine terraces, the present fold of the ocean bottom and the fracture of the crust as a response to the approach of the African and Eurasian plates, which will come to collide in a geological future.
The geologists who have taken part in the study have been able to identify a wide variety of tectonic structures (different kinds of faults and folds) which are simultaneously active and will help to characterize the seismic danger of the area. Another novelty of this work is connected with the formation of the southern mountainous front of the mountain range, a determinant factor in the evolution of the coast line in the last ten million years.
These results have been published in four international journals, like Journal of Structural Geology, and in Spanish, Italian and Czech ones, besides expositions in national and international conferences.
The COST European program, financed by the European Union, has given rise to contributions between both work teams, facilitating the sharing of the knowledge acquired in each area, the interchange and collaboration in common projects with other participating countries such as Italy and Romania.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
