Shocking satellite image shows before and after eruption of Anak Krakatau

Officials have released satellite images of Anak Krakatau volcano, both before and after the eruption which left hundreds dead in Indonesia.

The volcano's eruption caused a landslide, which in turn triggered a deadly tsunami.

Officials have since widened the exclusion zone around the volcano, fearing further eruptions.
