A new study led by the Institut de Ciències del Mar (ICM-CSIC) in Barcelona and the Institució Catalana de Recerca i Estudis Avançats (ICREA) has revealed the exact location of the boundary between the European and African tectonic plates, located in the Alboran Sea region. The work also evaluates its potential capacity to produce large earthquakes that, in turn, could trigger devastating tsunamis on the coast.
