Anak Krakatau eruption July 2009: vulcanian explosions
After a 36 hrs pause in activity between the evening of 30 June and the morning of 2 July, Anak Krakatau started again with powerful vulcanian explosions. The largest of these explosions were preceded by an inflation and shaking of the active cone or lava dome, triggering rock-slides from its flanks, until the plug gave way in giant explosions ejecting a rapdly expanding mass of red-hot lava, solid rocks, and large amounts of ash, forming plumes of up to 2 km heights.
