Ras Siyyan or Ras Siyan (Arabic: رأس سيان) is a peninsula in the Obock Region of Djibouti, on the Bab-el-Mandeb strait (between the Red Sea and the Gulf of Aden), about 20 km southwest of Perim Island. The peninsula consists of a reddish volcanic hill about 1.2 by 0.5 km and 138 m high, connected towards to the mainland by a low sandy strip that stretches south by about 5 km while widening from 500 to 800 m. The Ras Siyyan volcano is currently inactive but young, having erupted through a 21,000-year-old coral reef formation.

  • Ras Siyyan or Ras Siyan (Arabic: رأس سيان) is a peninsula in the Obock Region of Djibouti, on the Bab-el-Mandeb strait (between the Red Sea and the Gulf of Aden), about 20 km southwest of Perim Island. The peninsula consists of a reddish volcanic hill about 1.2 by 0.5 km and 138 m high, connected towards to the mainland by a low sandy strip that stretches south by about 5 km while widening from 500 to 800 m. The Ras Siyyan volcano is currently inactive but young, having erupted through a 21,000-year-old coral reef formation. To the west of Ras Siyyan there is a shallow marshy bay or lagoon, about 2.5 km wide, protected on the north side by shallow coral banks. The bay is fringed with patches of mangrove bushes (Avicennia marina), in spite of the little input of freshwater. Abundant sea grasses (chiefly Halodule and Thalassia species) form large beds in the bay, and Sharks breed there in October. An isolated white rock, Rocher Siyyan, lies in the bay about 800 m southwest of the volcanic hill. The hill of Ras Siyyan is sometimes considered the seventh of the Seven Brothers (Sawabi) islands; the other six lie from about 4.5 km to 14.5 km to the east. (en)
  • Ras Siyyan ou Ras Siyan (em árabe: رأس سيان ) é uma península na região de Obock, no Djibouti, no estreito de Babelmândebe (entre o Mar Vermelho e o Golfo de Áden), a cerca de 20 km a sudoeste da ilha de Perim . A península consiste em uma colina vulcânica avermelhada com cerca de 1,2 por 0,5 km e com 138 metros de altura, conectada em direção ao continente por uma faixa de areia baixa que se estende para o sul por cerca de 5 km, enquanto se alarga de 500 para 800 m. O vulcão Ras Siyyan é atualmente inativo, mas jovem, tendo entrado em erupção através de uma formação de recife de coral de 21.000 anos de idade. A oeste de Ras Siyyan, há uma baía ou lagoa rasa e pantanosa, com cerca de 2,5 km de largura, protegida no lado norte por margens rasas de coral. A baía é cercada por áreas com manguezais (Avicennia marina), apesar da pouca entrada de água doce. Gramíneas marinhas abundantes (principalmente espécies dos gêneros Halodule e Thalassia) formam grandes leitos na baía, e os tubarões reproduzem-se em outubro. Uma rocha branca isolada, Rocher Siyyan, fica na baía a cerca de 800 m a sudoeste da colina vulcânica. A colina de Ras Siyyan às vezes é considerada a sétima das Ilhas Sawabi; as outras seis ficam entre 4,5 a 14,5 km a leste. (pt)
