此地形是什麼
The southern Red Sea narrows to the Strait of Bab el-Mandeb between Yemen and the Horn of Africa, the outlet for Saudi Arabia's Red Sea terminals and for Suez-bound traffic. Its Yemeni shore passed to the Houthi movement in September 2026; the strait itself stayed open, and the module keeps those two facts apart.

移動集中之處
自然特徵
- 主要地形
- 一片位於阿拉伯與非洲海岸之間的狹長海域，邊緣分布著礁石與島嶼，南端收窄為一道寬約三十公里的海峽，位於葉門的Ras Menheli與吉布地的Ras Siyyan之間。Perim（Mayyun）島位於海峽中，將其分為兩條水道：靠近葉門海岸的狹窄東水道，以及較寬的西水道，分道通航帶即經由西水道。海峽以北，葉門海岸是一片低窪炎熱的平原——Tihama——荷台達是其主要港口，摩卡則是其歷史港口；Hanish與Zuqar群島位於近海。在沙烏地一側，海岸從南部的Jazan向北延伸至延布的碼頭與吉達港。
- 機動意涵
- The strait is the only southern exit from the Red Sea, and the Suez Canal the only northern one; everything that leaves Yanbu for Asia passes Bab el-Mandeb unless it takes the Cape. The July 2026 Houthi blockade of shipping to and from Saudi ports cut transits by about a quarter and sent Saudi Asia-bound crude north through Suez instead, turning a voyage of about twenty-four days into one of about fifty-four. The wider channel lies west of Perim, so presence on the island changes who is nearest the lanes, not whether they are usable; the module records the advance and does not infer a closure from it.
- 季節性制約
- 紅海南部是地球上最熱的海域之一；夏季的霾與亞丁灣的季風影響的是能見度與小艇航行條件，而非深吃水船舶的通行。Tihama外海的沙塵暴是反覆出現的沿岸現象。
- 水域與天然屏障
- Bab el-Mandeb is the barrier, and it has two shores: Yemen on one side, Djibouti and Eritrea on the other, with Perim between. That is why a change of hands on the Yemeni side is presence rather than control — the western channel and the African shore are not affected by it. Inside the Red Sea the reef belts on both coasts keep deep-draught traffic to the central channel.
- 城市化與聚落
- Sparse on the Yemeni side outside Hodeidah, the country's principal Red Sea port and the entry for most of its imports; Mokha is small and Perim uninhabited but for garrisons. The Saudi side carries Jeddah, the kingdom's largest Red Sea city, the Yanbu industrial city and Jazan's refinery and economic city in the south, all within reach of the strike waves of 2026.
廣泛的作戰意義
The Red Sea is where the Hormuz problem goes when it leaves the Gulf. The east–west pipeline was built so that Saudi crude could avoid one contested strait, and it delivers that crude to a sea whose southern exit is contested in its own right by a movement that has declared Saudi shipping its exception. From July 2026 the region's principal Hormuz alternative therefore depended on a waterway that was itself blockaded for the ships it served, and from 10 September on a line that was itself shut; the two chokepoints are one coupled system, and this record is the geography of the second half of it.
已觀察
The Houthi movement declared a blockade of shipping to and from Saudi ports in July 2026; transits fell by about a quarter. On 10–11 September it took Mokha, Dhubab, Perim and Zuqar. No independently observed interference with non-Saudi shipping from the new positions has been read, and Al Jazeera reported no official Houthi announcement of control over the strait.
經評估
Presence on the Yemeni shore is a change in who is nearest the lanes and not a change in whether they are usable, and the module will keep that distinction until an act against a vessel is observed. What the advance does establish is that the Hormuz bypass's outlet is now held on one side by the party that has declared its blockade.
「觀察所得」是來源所顯示的內容。「經評估」是Vigil對其的解讀，附有此紀錄的信心等級。
仍然未知的事項
- The extent of the coastal control line is the movement's own claim and has not been independently verified.
- Yemen's internal war beyond the coast is outside the module and is not authored here.
