Details for: Adatarayama
The broad forested massif of Adatara volcano, seen here from the west, is composed of a group of stratovolcanoes capped by lava domes. The unvegetated area on the left summit ridge is a 1-km-wide circular crater that is breached by the Iwo-gawa (Sulfur River) on the west. The crater has been mined for sulfur. Seventy-two miners working in the summit crater were killed during an explosive eruption in 1900. Photo by Lee Siebert, 1988 (Smithsonian Institution).
