Description
Summary:The 1755 Lisbon earthquake & tsunami had one of the highest magnitudes in the history of Europe. The source mechanism requires generation at a subduction zone. Intensity distribution & tsunami modelling excludes the Gorringe Bank as a source area & suggests generation by the incipient convergence of the Atlantic with the Southwest Iberia & Morocco margin rather than at the less active Gulf of Cadiz Accretionary Prism. The comparison with the 2004 Sumatra earthquake & tsunami supports this interpretation. A tsunami warning alert system is urgent for the Atlantic. 2 Tables, 39 References.
