The Volcano Island Inside Another Volcano

Aogashima is a tiny Japanese island that sits inside a massive, active volcanic crater. Remarkably, a second, smaller volcanic cone sits right in the center of that crater, meaning people live inside a double volcano.

Located hundreds of miles from Tokyo, this remote island is actually a giant volcanic caldera containing a smaller volcano within it. It is one of the most isolated inhabited places in the world and remains active to this day. Steam vents are scattered across the island, which locals cleverly use to cook their food in natural geothermal saunas. It is a breathtaking example of life thriving in a geological pressure cooker.
