[:ja]トマ・ペスケ宇宙飛行士がISSから撮影した仏領ポリネシアのマウピハア島です。
マウピハア島は、タヒチなども含まれるリーワード諸島に属します。リーワード諸島は、山がちで火山岩の好例となっており、粗面岩、粗粒玄武岩、玄武岩で覆われています。サンゴ層によって山が持ち上げられているほか、溶岩を様々な形で見ることができます。リーワード諸島の火山活動は長年にわたって活動をしていないため、噴火口は侵食によってほぼ完全に消えてしまっています。

[Earthview Wonders] No.289: Maupihaa of French Polynesia🇵🇫
Astronaut Thomas Pesquet captured from ISS Maupihaa, an atoll in the Leeward group of the Society Islands.
The islands are mountainous, consisting of volcanic rock. They are formed of trachyte, dolerite and basalt. There are raised coral beds high up the mountains, and lava occurs in a variety of forms, even in solid flows. Volcanic activity ceased so long ago that the craters have been almost entirely obliterated by erosion.
Beautiful scenery on the ground is as follows.
