1755年，里斯本大地震（估计震级为8.7级）造成伊比利亚南部和摩洛哥西北部6万人死亡，并产生了5至10米高的海啸波。从他的角度来看，

讨论了地震构造震源的研究现状。最近的证据表明，直布罗陀下面的一个向东倾斜的俯冲带可能引起了这次地震。虽然这里没有记录到板间地震，但泥火山、变形沉积物的地震图像和热流数据的证据表明，俯冲是活跃的，孕震断裂带可能被锁定。2004年和2005年计划进行的许多航行可能有助于提供一个明确的答案。
In 1755, the great Lisbon earthquake (estimated magnitude 8.7) killed 60,000 people in southern Iberia and northwest Morocco and generated a 5- to 10-m-high tsunami wave. In his Perspective,

discusses the current research on the tectonic source of the earthquake. Recent evidence suggests that an eastward-dipping subduction zone beneath Gibraltar may have caused the earthquake. Though no interplate earthquakes have been recorded here, evidence from mud volcanoes, seismic images of deformed sediments, and heat flow data suggest that subduction is active and that the seismogenic fault zone may be locked. Numerous cruises planned in 2004 and 2005 may help to provide a definitive answer.
