This new cone, named Anak Krakatau (Child of Krakatoa), represents the next distinct phase in the eruption history of the region. A sector of the Anak Krakatau volcano slid into the sea, triggering a devastating tsunami that struck the coasts of Java and Sumatra.
Krakatoa Seismic Activity and Build Up of Anak Krakatau
In the early 20th century, a new volcanic island began to emerge from the debris of the old caldera. The 1883 eruption of Krakatoa stands as one of the most violent geological events in recorded history, a cataclysm that reshaped the island chain and sent shockwaves literally around the globe.
The iconic caldera collapse occurred when the magma chamber emptied and could no longer support the weight of the volcanic edifice, causing the center of the island to cave inward. Geological Precursors and Ancient Activity Long before the iconic cone of Krakatoa emerged, the region hosted a predecessor volcanic edifice known as Proto-Krakatoa.
Krakatoa Seismic Activity and Building Eruptions Before Anak Krakatau
This event, which occurred without a preceding major explosive eruption, highlighted the various hazard mechanisms associated with the volcano, from direct blasts to secondary effects like underwater landslides. Post-1883 Activity and the Formation of Anak Krakatau In the decades following the monumental 1883 event, the area remained geologically restless.
