Under the waters of the eastern Alborán Sea and buried at the shadow of an old volcanic edifice lies a body of sediments that may have been originated by a massive flood that refilled a partially desiccated Mediterranean 5.3 million years ago. This mass of sediments, seen in seismic reflection profiles, represents new possible megaflood deposit of the so-called Zanclean flood, according to a new article published in “Earth-Science Reviews" journal.

Researchers at the Institute of Earth Sciences Jaume Almera of the Spanish National Research Council (ICTJA-CSIC) have described in a new study the effects of the lithospheric structure on the topography of the Strait of Gibraltar area. This new researh shows the deep structure of the plate boundary between Africa and Eurasia across the Gibraltar Arc. It describes the distribution of density, temperature and composition of the lithosphere and sublithosphere ( up to 400 km deep).

A fast collision rate between tectonic plates and a young age are two factors that favour the sinking of the lithosphere in the mantle, according to a new study made by researchers from the Institute of Earth Sciences Jaume Almera of the Spanish National Research Council (ICTJA-CSIC). The study has been published recently in the Scientific Reports journal.

A team of researchers at Institute of Earth Sciences Jaume Almera of the Spanish National research Council (ICTJA-CSIC) have analysed the seismic signals generated by the variations in water flow of the Aragón river due to the snow melting in its upper basin. In the study, published in the journal PLOS ONE, the researchers describe identifying snowmelt episodes from the temporal variation patterns in the seismic data.

A new study conducted by an international team of scientists has found new evidence that support the hypothesis of the megaflood occurring during the Zanclean period, a giant flood in which water from the Atlantic poured back into the Mediterranean sea and ended the Messinian Salinity Crisis (MSC) 5 million years ago. The study, led by Professor Aaron Micallef from the University of Malta, has been published in the Scientific Reports journal.
