モザンビーク海峡
Two of the islands—Juan de Nova and Europa—and the Bassas da India atoll lie in the Mozambique Channel west of Madagascar, while a third island, Tromelin, lies about east of Madagascar and the Glorioso Islands lies about northwest of Madagascar. Also in the Mozambique Channel is the "Banc du Geyser", a submerged reef considered a part of the Glorioso Islands by France and the Comoros.
