Photo Gallery

The forested Kurikoma volcano is seen from the SSE with its summit at the right-center, the satellitic cone of Daichimori on the left, and Higashi-Kurikoma on the right. On the opposite side of the volcano, the summit is cut by a 4-km-wide caldera breached to the north that is partially filled by the Tsurugi-dake central cone, once mined for sulfur. Minor phreatic eruptions have occurred in historical time from the central cone.
