Photo Gallery

Steep cliffs up to 300 m high ring the small island of To-shima on three sides. To-shima-mura, the port village of the island, lies at the far left in this view from the west. To-shima lies about 20 km west of the main volcanic front of the Izu-Marianas arc. The latest eruption of the 508-m-high To-shima stratovolcano occurred between about 8000 and 4000 years ago.
