Aogashima – one of the islands of the a volcanic island arc South of Japan (see the right of the Picture for a depression in the ocean –> Izu-Bonin Trench)
Aogashima, along with several other volcanic islands, form the Izu Islands – a volcanic island arc (possibly due to the convergence of Pacific plate and Philippine(?) plate)
For the residents of Aogashima, an island about 200 miles due south of Tokyo, 1785 was an unforgettable year. Although they weren’t alive to witness the deadliest event in island history, they know what unfolded all too well—and what they know hasn’t changed their mind about living atop a real-life volcano.
They’ve heard the stories about how, on May 18, the ground began to shake. Giant plumes of gas and smoke billowed out from the mouth of the island’s volcano, shooting rocks, mud and other debris into the sky. By June 4, the island’s 327 residents had no choice but to evacuate, but only about half succeeded and the rest perished. Those who live on the island that’s home to a volcano still registered as active by the Japanese Meteorological Agency, the governmental agency responsible for monitoring the nation’s 110 active volcanoes, know that there’s always the chance that history could repeat itself. But Aogashima’s inhabitants are willing to take that risk
