Raung volcano (East Java, Indonesia): photos August 2015

With a small group we climbed Raung during 14-15 August 2015. The hike involves approx. 20 km trekking and almost 2000 m climbing along a mostly overgrown path as only few people visit this spectacular volcano, even though it is one of Indonesia's most active ones.
We might have witnessed the end of the large 2015 summit eruption, which during June-early August produced large lava flows, lava fountains and significant ash plumes.

View of the immense, 2 km wide summit crater, a small caldera surrounded by steep walls 4-500 m deep. It reminds a lot of Nyiragongo. The recent eruption has covered the whole floor with fresh lava and built a large cinder cone in the SE part (view is from the north). (Photo: Tom Pfeiffer)

Dark jets of ash and blocks as well as white steam expelled suggest that interaction of magma and water inside the conduit drives these eruptions (so-called phreatomagmatic activity). (Photo: Tom Pfeiffer)
