The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Lihir volcano forms the small Lihir Island, the largest of a group of island north of New Ireland (Papua New Guinea). It is the largest of the volcanic chain east of New Ireland. Lihir is composed of 5 overlapping basaltic stratovolcanoes, including Luise, Kinami, and Huniho. 4 young submarine volcanoes offshore Lihir Island belong to the complex as well.
Luise is the youngest volcano of Lihir and contains an elliptical 5.5 km long and 3.5 km wide caldera open to the sea, forming Luise Harbour. The caldera rises with steep walls 700 m above the sea, and its floor is covered by debris from the walls. It probably formed around 400,000 years ago.
In the center of the caldera, a strongly hydrothermally altered lava dome is present and displays extensive thermal activity along its margins.
Ibu volcano photos: Ibu in Halmahera is one of the most active, but rarely visited volcanoes in Indonesia. A spectacular lava dome is growing inside the volcano's breached crater, with frequent explosions.
