On October 16, 1979: a landslide at the Nice Airport, an aseismic submarine landslide, and two tsunamis that struck the coast near Nice. The two waves struck the coast between the Italian border and the town of Antibes (60 miles; 96 km).〔Allaby, M. (2004). A Chronology of Weather. Infobase Publishing.〕 They reached 3 m high near Nice and 3.5 m〔Sahal, A., & Lemahieu, A. (2011). The 1979 nice airport tsunami: mapping of the flood in Antibes. Natural hazards, 56(3), 833-840.〕 at La Salis (Antibes) and decreased in amplitude from there. ==Causes== The origin of these events has been a subject of academic and judicial debate.〔Lee, H.

Continental margin sedimentation: from sediment transport to sequence stratigraphy, 213-274.〕 A hypothesis said that it was the landslide at the Nice airport; the other, the underwater slide.〔Seed, H. B. (1988). The landslide at the Port of Nice on October 16, 1979. Earthquake Engineering Research Center, University of California.〕 In the first hypothesis, there was a 150 m3〔Nisbet, E. G., & Piper, D. J. (1998). Giant submarine landslides. Nature, 392(6674), 329-330.〕 slide off Nice airport while constructing the fill of a new airport, perhaps as a consequence of this work. This landslide would have caused the first tsunami. After that, the material of this slide would have caused the submarine slide that would have caused the second tsunami.〔 In the second hypothesis, the major natural submarine landslide (~8.7 km2) that occurred offshore Nice caused a tsunami which would have caused a landslide of the fill of the new airport. This landslide caused another tsunami.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1979 Nice tsunami」の詳細全文を読む スポンサード リンク
