The 20 x 26 km Kutcharo caldera, seen here from its west rim, is the largest of a cluster of calderas in NE Hokkaido. It formed around 30,000 years ago. Naka-jima, a Holocene post-caldera lava-dome complex, forms the large island at the left in Lake Kutcharo, which fills much of the western half of the caldera. The Atosanupuri stratovolcano and lava dome complex is located near the center of the caldera, east of the crescent-shaped Lake Kutcharo. Atosanupuri erupted about 1000 years ago, and remains fumarolically active.

A cluster of lava domes is located in the center of Kutcharo caldera, partially filled by Lake Kutcharo (upper right). Light-colored areas of hydrothermal alteration cover the slopes of Atosanupuri (left), seen here from the east with the rounded Sawanchisappu lava dome to its right. The far western wall of the 20 x 26 km Kutcharo caldera lies in the clouds at the far end of the lake.

Atosanupuri lava dome, its hydrothermally altered flanks only sparsely vegetated, was emplaced about 1000 years ago. This marks the latest known eruption of Kutcharo volcano. The 900-m-wide dome was constructed within a 1-km-wide explosion crater. Atosanupuri is one of a cluster of lava domes that occupy the eastern side of Kutcharo caldera.

Intense fumarolic activity occurs on the margins of Atosanupuri lava dome and along fissures cutting the dome. Constant high-temperature emisson of steam and gas has extensively altered rocks on the dome. Areas of sulfur deposition such as this are common and have been mined since 1887.

Souvenir vendors at Atosanupuri volcano take advantage of intense fumarolic activity to cook baskets of hard-boiled eggs for visiting tourists. Atosanupuri is the youngest of a group of lava domes on the east side of Kutcharo caldera. Its last known eruption occurred about 1000 years ago, but fumarolic areas abound on the margins of the dome and on radial fissures cutting it.
