@article {LoIacono2012a, title = {{Large, deepwater slope failures: Implications for landslide-generated tsunamis}}, journal = {Geology}, volume = {40}, number = {10}, year = {2012}, month = {aug}, pages = {931{\textendash}934}, abstract = {Deepwater landslides are often underestimated as potential tsunami triggers. The North Gorringe avalanche (NGA) is a large (\~{}80 km3 and 35 km runout) newly discovered and deepwater (2900 m to 5100 m depth) mass failure located at the northern fl ank of Gorringe Bank on the southwest Iberian margin. Steep slopes and pervasive fracturing are suggested as the main preconditioning factors for the NGA, while an earthquake is the most likely trigger mechanism. Near-fi eld tsunami simulations show that a mass failure similar to the NGA could generate a wave >15 m high that would hit the south Portuguese coasts in \~{}30 min. This suggests that deepwater landslides require more attention in geo-hazard assessment models of southern Europe, as well as, at a global scale, in seismically active margins. {\textcopyright} 2012 Geological Society of America.}, issn = {0091-7613}, doi = {10.1130/G33446.1}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-84868693659\&partnerID=tZOtx3y1}, author = {Lo Iacono, C. and Gr{\`a}cia, E. and Zaniboni, F. and Pagnoni, G. and Tinti, S. and Bartolome, R. and Masson, D.
