          <datacite:description xml:lang="ja" descriptionType="Abstract">福山内港地域は瀬戸内海につながる福山港入江の周辺地域であり，海洋由来の自然災害による危険性を有している．南海トラフ地震発生時の福山港沖合では，津波によって通常潮位より最大1.4mの海面上昇が生じると予測されている．この津波が福山港入江に侵入した際の海面変動を数値計算で求めたところ，津波は最大2.8mまで増幅することが示された．津波の到達が満潮時と重なった場合，平均海水面からの高さが最大4.6mの海面上昇となる．さらに，副振動や吸い上げ効果，吹き寄せ効果によって，最大1m程度の海面上昇が加わることも予想される．福山内港地域の護岸堤防の一部は標高3.5m程度であり，地震動による堤防の破損がない場合であっても平野内部に津波が侵入する危険性があると言える．</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">The Fukuyama inner harbor area is located around the Fukuyama Port Inlet that connects to the Seto Inland Sea.This area has some risk of natural disasters from the ocean. The Nankai Trough Earthquake is predicted to cause a sea level rise of 1.4 meter in the offshore area of Fukuyama Port due to tsunami. We calculated the tsunami propagation in the inlet and showed that the tsunami would be amplified up to 2.8m in maximum height. If the tsunami would approach in full tide, the sea level could rise by about 4.6 meter. In addition to that, the secondary undulation, the inverse barometer and wind-drift effects could cause an additional rise of sea level by 1 meter. Nevertheless, a part of the embankment around the inlet is about 3.5 m high. Therefore, there is a risk of tsunami intrusion into the Fukuyama plain, even if the embankment would not be damaged by severe seismic motions.</datacite:description>
