Down here, the whine of mosquitoes grows much louder, and the humidity becomes more and more oppressive. Jets of steam hiss menacingly as they escape from underfoot, hinting at the island’s lethal secret. Something terrible lurks just below Aogashima’s crust, you see – and it’s more than capable of claiming lives.
Yet despite Aogashima’s terrible power, it’s actually surprisingly small. The island measures just over 2 miles long, in fact, and slightly more than 1.5 miles wide. And a generous portion of the isle is taken up by an impressive crater that’s almost a mile across. A little hillock sits within the hollow, complete with its own diminutive depression at the top.
And although more than 200 miles of ocean separates the little island from the sprawling metropolis of Tokyo, Aogashima has close links to Japan’s capital. After all, Tokyo administers the 200 or so people that call Aogashima home. The city performs similar services for other isles in the Pacific, too. Iwo Jima and Okinotori are also both governed by the metropolis – despite the fact that they’re 750 miles and 1,080 miles away from it respectively.
