Tore, Volcanic formation in Bougainville, Papua New Guinea.

Tore is a volcano in northern Bougainville, Papua New Guinea, whose Pleistocene eruptions left a caldera measuring 6 km by 9 km and two ignimbrite fans running west to the coast. A lava cone sits on the caldera's southern rim, and lava flows from it spread across the surrounding ground. A nearby ash cone keeps well-preserved shapes.

Tore's violent Pleistocene eruptions produced two ignimbrite fans that stretch west to the coast of northern Bougainville, along with a caldera measuring 6 km by 9 km. After the caldera collapsed, a lava cone grew on its southern rim and became the source of later lava flows. Well-preserved surfaces on that cone and a nearby ash cone point to a recent date for both.

The volcano lies in northern Bougainville, where the local population lives along the coast west of the ignimbrite fans. The name Tore is used for the volcano itself; the sources record no specific stories, ceremonies or traditions attached to it. Visitors pass through coastal villages on the approach, and arranging access with local landowners is the usual practice.

Tore lies in northern Bougainville, and the source records no road access; plan on boat or helicopter. The 6 km by 9 km caldera and the lava cone on its southern rim are the main features to locate on approach. The two ignimbrite fans run west to the coast, giving a natural line of orientation from the sea.

The lava cone sits on the caldera's southern rim, not inside the crater, and its fresh-looking form plus a nearby ash cone point to a recent age. The two ignimbrite fans from the Pleistocene eruptions reach west to the coast.
