三陸復興国立公園 (2)
碁石海岸を含む国立公園南部にあたる土地は、約4億年前の地殻変動によって北に運ばれてくる前は、赤道付近に位置していました。リアス海岸の不規則な凹凸は、氷河が溶けて海面が上昇し、川の谷間が浸水してできた数々の入り江や半島です。リアス海岸の特徴の一つは、多くの湾が穏やかな水を湛えていることで、これらは海藻や牡蠣、特定の魚類といった海産物の養殖にぴったりの生息域となっています。狭い入り江は、津波の高さや破壊力を増大させやすいため、地震の際は 危険にもなりえます。

Sanriku Fukko National Park (2)
The land that forms the southern section of the park, including the Goishi Coast, was located near the equator before tectonic plate movement carried it north around 400 million years ago. The irregular contours of the ria coast form a series of inlets and peninsulas created when rising seas from melting glaciers inundated the river valleys. One feature of the ria coast is the calm water of the many bays, which makes them an ideal habitat for cultivating marine products such as seaweed, oysters, and certain species of fish. The narrow inlets can also be dangerous when earthquakes occur, as they tend to magnify the height and destructive power of tsunamis.
