Voyage Unzen

The volcanic complex of Mount Unzen is in the Shimabara Peninsula, which reaches out into Ariake Bay. The town centre of Shimabara is 6 km (about 4 miles) from the peak as the bird flies. The town itself is located by the Bay and comprises 45,000 inhabitants. Part of the town was destroyed and the rest is still threatened by the many pyroclastic surges that came from the volcano between 1990 and 1995.
