Papandayan is the volcano you can actually see on satellite images (e.g. Google Earth) even from a view point 800 km above ground – it is the white patch of a collapse scar that stands out in stark contrast from the dark green forest. The volcano sits at the southern end of the Kendang-Papandayan mountain range.
G. Papandayan is generally said to be 2665 m high but there seems to be some confusion as to location and actual height Continue Reading

It’s always good to have a spare volcano in your desert – for scenery, for tourists, for sulfur, for energy, whatever – as long as it doesn’t erupt. There are far more volcanoes in the world which have not erupted in the last 10 000 years than those considered presently active. With most of them we will never know whether they are truly extinct or just keep their heads down. And then there are those Continue Reading
On the volcanic front of the New Britain Island Arc: from left to right, Ulawun, Lolobau in the foreground, and Bamus volcanoes in New Britain. (© Richard Arculus, via Flickr)
Ulawun stratovolcano is a very steep and 2334 m-high mountain on the central-north coast of New Britain, P.N.G. Bamus stands 2248 m tall beside him, and both have a problem – they’re growing too high. Both Ulawun and Bamus are more than 400 m taller than all other stratovolcanoes in the 1000-km-long Bismarck Volcanic Arc. Given existing faults and scarps of historical events, concerns are that flank failure is in the cards for both volcanoes. Locally the three volcanoes Ulawun, Bamus (to the SW of U.) and Likuruanga (to the NE of U.) are better known as the “Father group”: After myths told by the Nakanai people these three are named Father, South Son and North Son.
