Bromo volcano (East Java, Indonesia), Feb 2011: strombolian activity

Most of the material ejected during its ongoing eruption is ash and blocks from the crater and conduit walls. Incandescent material (i.e. fresh magma) was first observed at Bromo in Dec 2010. Mild strombolian activity was visible at night during our tour from 15-19 Feb, usually accomanied by hissing and soft explosion sounds. At least two different vents were active inside Bromo's crater. Most of the strombolian activity took place from the vent in the W half (right in the pictures) of the crater, while a vent in the eastern half (left) was the principal site of ash emissions and occasional powerful explosions accompanied by loud detonations and shock waves rattling windows in up to several kilometer distance.

A powerful vulcanian-type explosion shakes the ground. Many incandescent bombs are thrown many hundreds of meters into the night sky, and many of them land outside the crater. Note, that most blocks are actually NOT glowing, making a further approach to Bromo quite dangerous. (Photo: Tom Pfeiffer)
