Red Island (Heard and McDonald Islands)
|Archipelago||Heard and McDonald Islands|
Red Iceland ( English for Red Island is) an up to high island from "dark red lava " in the archipelago Heard and McDonald Islands in the southern Indian Ocean . It is located 800 m north of the Laurens Peninsula from Heard , with which it is connected by a sandy, low and narrow isthmus , a so-called tombolo . This in turn is characterized by the centrally located Roman lagoon .
The island consists of an ash cone and an adjoining lava field . Only the eastern flank of the cone, consisting of a 2 m thick layer of trachyte , which in turn is covered by a 30 m thick layer of ash and breccia , has been preserved. The western part, on the other hand, has been washed away by the sea. In the longitudinal section through the cliffs close to the lake on the north side, five to six lava flows are included; an older lava flow already covered with vegetation runs east and south.
It received its descriptive name from the American seal hunters who operated in the waters around the archipelago from 1855. The island is "easily distinguishable by its color."
