Anak Krakatau emerged from the caldera left by the 1883 Krakatoa eruption and has been growing through repeated eruptions since 1927.
In December 2018, Anak Krakatau experienced a flank collapse that generated a deadly tsunami in the Sunda Strait. The waves struck coastal areas of Java and Sumatra, killing over 400 people. Ujung Kulon National Park, home to the entire Javan rhino population, lies directly within this strait. Reports indicated that parts of the park were affected by flooding and debris. Fortunately, post-event monitoring did not record a catastrophic loss of rhinos. However, the event demonstrated how close the species lives to geophysical disaster. Anak Krakatau remains active, with ongoing eruptive episodes. The rhino population exists within the radius of future volcanic instability.

The 2018 event triggered renewed disaster modeling for Ujung Kulon. Conservation planners evaluated elevation maps to identify higher-ground refugia within the park. Infrastructure such as ranger stations required reassessment for resilience. Unlike controlled threats such as poaching, volcanic hazards cannot be deterred. The rhino population effectively inhabits a dynamic geological frontier. This adds a non-anthropogenic layer of extinction risk to an already constrained species.
For conservation biology, the lesson extends beyond Indonesia. Species confined to single reserves near active fault lines face compound risk scenarios. Climate change may further alter storm intensity and coastal dynamics in the region. The Javan rhino’s story now intersects with volcanology and coastal engineering. Its continued survival depends not only on habitat protection but on the unpredictable behavior of Earth’s crust. Evolutionary endurance meets tectonic uncertainty.
