Sanriku Coast
The Sanriku coast (Japanese三 陆 海岸, Sanriku kaigan ) is a Japanese coast on the Pacific.
Name
The name Sanriku - literally " three Riku " - refers to the three provinces Rikuzen, Rikuchu and Rikuo, extending over the area of the three prefectures before the establishment of the prefecture system.
Geography
The Sanriku coast extends over a length of 600 km from Hachinohe in Aomori Prefecture in the north to the Oshika Peninsula in Miyagi Prefecture in the south. The northern part is characterized by steep tilting and the southern part, from Miyako in Iwate Prefecture, due to its estuary.
The coast, particularly the southern part is in serious danger for two reasons by tsunami damage. Firstly, the coast is opposite a subduction of the Pacific plate, which results in an increased number of earthquakes with great strengths, in turn, trigger large tsunamis. Examples are the Jogan - Sanriku earthquake 869, the Keicho - Sanriku earthquake in 1611, the Meiji- Sanriku earthquake in 1896, the Showa Sanriku earthquake in 1933, the Tokachi earthquake in 1968 and the Tōhoku earthquake in 2011. Causing the other the highly irregularly shaped bays of Riasküste waves at a high degree of refraction (refractive ), which in turn increases the flood height, so that thereby the destructive power of tsunamis is enhanced.
Communities
The communities along the coast are:
- Aomori Prefecture Hachinohe, Hashikami
- Iwate Prefecture: Hirono, Kuji, Noda, Fudai, Tanohata, Iwaizumi, Miyako, Yamada, Otsuchi, Kamaishi, Ofunato, Rikuzentakata
- Miyagi Prefecture: Kesennuma, Minamisanriku, Onagawa, Ishinomaki
Conservation
The section of Kesennuma in Miyagi until after Kuji in Iwate belongs to Rikuchu - Kaigan National Park. The southern part of the Sanriku coast is the Minamisanriku- Kinkazan Quasi National Park.
Fishing
Off the coast coming from the north and the Oyashio cold current from the east coming warm ocean current Kuroshio meet together. Due to this feature include the off-shore waters - Sanriku - oki (三 陆 冲, dt " Sea off Sanriku " ) called - to the three richest fishing grounds in the world.
