An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group at Pompeu Fabra University and with the participation of Jordi Ibáñez-Insa, researcher at GEO3BCN-CSIC, has advanced in the understanding and preservation of archaeological sites and in improving their analysis and surveying, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a rapid, inexpensive, non-invasive procedure, which enables generating an additional archaeological record from the anthropogenic deposit by analysing chemical elements, combined with geostatistics.
San Jerónimo and Negro de Chorrillos are two shoshonitic monogenetic volcanoes placed in the Pluna plateau, in the Central Volcanic Zone of the Andes, in the north of Argentina. They are younger than previously thought. They erupted 144.00 and 51.000 years ago respectively, according to a new study that has dated and characterized the materials erupted from these volcanoes by using new methods The paper has been recently published in the "Journal of South American Earth Sciences".
A team of researchers of GEO3BCN-CSIC has started a new experiment aimed to use a buried fiber-optic cable as a seismic sensor in Barcelona. The experiment uses the DAS technology (Distributed Acoustic Sensing) which allows to measure the small deformations along the cable caused by vibrations by using laser pulses. The experiment is made possible by the collaboration of Reintel Company (Red Electrica group), who owns and provides the cable network, and the University of Michigan, owner of the DAS interrogator unit.
Jordi Ibañez Insa and Soledad Álvarez Pousa, members of the staff of the GEO3BCN-CSIC X-Ray Diffraction service (XRD), characterised the Salvador Dali’s jewel “The Angel Cross” by using X-Ray fluorescence spectrometry (XRF) in collaboration with Dalí Musem.
In August of 2009, typhoon Morakot passed over Taiwan, triggering over 22,000 landslides and adding another chapter to the forced migration of indigenous settlements in the mountainous areas. A new study recently published in the journal Tectonophysics has analyzed how extreme weather such as that caused by Morakot, when coupled with local geological conditions, can trigger landslides that have caused two forced settlement relocations of one Paiwan group in southern Taiwan in the last 350 years.
Magnetostratigraphic dating is one of the several paleomagnetism tools, being a field that was essential to develop the tectonic plate’s theory.
Agustín Lobo took part in the second edition of the workshop " Hyperspectral Sensing meets Machine Learning and Pattern Analysis (HyperMLPA)" which was held online during March 24-26 as a part of the scheduled scientific program of the Spectro Expo 2021. Lobo gave the talk entitled "Machine-Learning Classification Of Proximal Conventional And Hyper-Spectral Imagery" in which the researcher explained the work developed in collaboration with the company Lithica for the iTarg3T project.
Seismic data might be used, under certain conditions, as a useful proxy to monitor the level of human activity in urban environments, providing similar details to those offered by other common mobility indicators, according to a new study made by researchers from Geosciences Barcelona - CSIC (GEO3BCN-CSIC). Seismologist Jordi Díaz is the leading author of the study that has been published recently in the journal “Solid Earth”. Mario Ruiz (GEO3BCN-CSIC) and José Antonio Jara, from the from Institut Cartográfic i Geologic de Catalunya (ICGC) are the other authors of the study.
After nearly one month and a half of intense seismic activity caused by the moving magma beneath the surface, Galdungaladur volcano erupted last 19th march. The new eruptive fissure emitting lava and gases was formed in the southernmost part of the Reyjkjanes peninsula, 40km away from Reykjavic. Researchers from the University of Iceland, who are also members of the EVE project (European Volcanoes Early Warning System), led by Geosciences Barcelona (GEO3BCN_CSIC), have been closely monitoring the pre-eruption process of Galdungaladur volcano and its unrest phase. This eruption has provided a perfect scenario for testing in real-time the different forecasting tools that are being developed by the EVE project.
Elisabet Beamud, del Laboratorio de Paleomagnetismo (CCiTUB-GEO3BCN), participó en una nueva sesión de muestro arqueomagnético en el yacimiento arqueológico de la cueva del Gegant el pasado viernes, 19 de marzo, junto a Joan Daura y Montse Sanz, investigadores del Seminari d'Estudis i Recerques Prehistòriques de la UB, y Miguel Garcés, del Instituto de Investigación Geomodels y departamento de Dinámica de la Terra i l’Oceà de la Universidad de Barcelona (UB).
