The town of Hijiori lies in the left foreground, along the banks of two rivers that transect the caldera floor. The low 2.5-km-wide caldera formed during a large eruption between about 9500 and 11,000 years Before Present accompanied by pyroclastic flows and tephra fall that extended to the east and reached the Pacific coast.
