'This photo shows Anak Krakatau at the start of its eruptive phase in August 2018, taken whilst on vacation. This Strombolian eruptive style is building up the flanks of the central cone, out of unconsolidated tephra, with little real strength. Eventually, this constructive phase culminated with the collapse of the southwestern flank (to the left in this image). The water displaced by this slope's failure generated a devastating tsunami with no warning, and claimed more than four hundred lives on 22nd December 2018.'
