The tsunami of 30 July 1627 was the strongest tsunami in the Adriatic in moderm history. It was caused by disastrous earthquake (X MCS) that struck the Gargano peninsula. According to macroseismic data the epicentre was located inland near Lesina and S. Severo (Foggia) but tsunami data suggest that the tsunamigenic sources was located offshore (Tinti and Piatanesi, 1996). The tsunami was described in a number of contemporary documents. Along the Gargano coast between S. Nicandro and the Fortore River mouth the sea first withdrew 2-3 miles, leaving the Lesina Lake completely dry, followed by flooding of the coast and the village of Lesina (Foglia, 1627; Anonymous, 1627; De Poardi, 1627; Ballerani, 1627). Effects of the tsunami were dramatic: “the Abbey of Ripalda was swallowed by water” (Del Vasto, 1627), and “in Manfredonia the waves reached halfway up the city walls” (Cerqua, 1627). Sea withdrew also at the Foro River mouth (Antinori, 1782), while low laying land north of Pescara (between Silvi and Mutignano), which is more than 100 km from the epicentre, was also flooded (Boschi et al., 1995).
