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.

When the most powerful of explosions occurs on the afternoon of 3 July, we need to make a quick escape with the boat, because bombs and blaocks fall several hundred meters from shore. We manage to increase our distance quickly by more than 200 meters; nevertheless, few blocks still land around the boat. Due to the circumstances, the movement and suddenly finding myself on the wrong side of the boat... framing of photos was not easy, but the spashes of many blocks landing in the water where we just were are barely visible.
