Nature Communications: Tsunamis in Africa may be caused by plate boundary



The article, published in Nature Communications, a journal dedicated to publishing high-quality research in the fields of biology, health, physics, chemistry and earth sciences, describes how the flaws in Plates underlying the African and Iberian Peninsulas have moved over the past five million years and what these movements have resulted in.

The system of faults in the plates underlying the African and Iberian peninsulas is capable of producing large earthquakes, which cause devastating tsunamis, according to research by the Institut de Ciències del Mar (ICM-CSIC) [The Institution for Marine Science] in Barcelona and the Institució Catalana de Recerca i Estudis Avançats (ICREA) [The Catalan Institution for Research and Advanced Studies] in Catalonia.
The experts who were responsible for the discovery concluded that the risks had previously been underestimated due to lack of data.

“These studies are a first assessment of the seismic and tsunami potential of these large faults, which until now were almost completely unknown to us and which must be carefully evaluated in future studies,” said Laura Gómez de la Peña, researcher at the ‘ICM-CSIC and leader. study author said.

Although studies aimed at discovering the geological structure of the subsoil of the Alboran Sea in the Mediterranean – where the border is – have been carried out since the 1970s, sufficient information could not be obtained until present due to inadequate machinery.

“We used the latest data acquisition techniques to conduct our study aboard the Spanish oceanographic vessel Sarmiento de Gamboa, and the processing was specifically designed to observe the structures now described for the first time,” said César Ranero, researcher at ICM-CSIC and professor at ICREA.
