Waiowa

Waiowa is a volcano in Oro Province, Papua New Guinea, rising about 640 meters above sea level. The summit features a crater lake surrounded by steep rock walls.

The volcano erupted in September 1943 after months of seismic activity, continuing with repeated eruptions until August 1944. These events significantly altered the surrounding landscape.

Indigenous communities near the volcano maintain traditional practices connected to the geological landscape of Oro Province and its natural formations.

The site is remote, located about 19 kilometers inland from Collingwood Bay on the island's interior. Visiting requires proper planning and awareness of challenging jungle terrain and local conditions.

The 1943-1944 eruptions created lahars and pyroclastic flows that destroyed vast stretches of forest and completely reshaped the terrain. The area still bears clear marks of these dramatic geological changes today.
