Background
Geologic history of the Kurikuma complex:The earliest eruptions from Higashi-Kurikoma began about 500,000 years agoand produced lava flows to the north and south. This stage was followed by the growth of the Higashi-Kurikoma (East Kurikoma) stratovolcano. The next volcanic edifice to form was Magusa-dake volcano on the western side of the complex, active until about 100,000 years ago. Construction of Magusa-dake's main cone concluded with lava flows to the east, SE, and west.
Daichigamori lava dome and Aguroshi-yama pyroclastic cone are located on the southern flank.
