The Sunda Arc is one of the most geologically active volcanic chains in the world.
Ujung Kulon lies along the Sunda Arc, a tectonically active zone formed by the subduction of the Indo-Australian Plate beneath the Eurasian Plate. This region includes Krakatoa and its successor, Anak Krakatau, both historically active volcanoes. Geological monitoring confirms continued eruptive episodes in recent decades. The Javan rhino population is entirely confined within this seismic landscape. Unlike species distributed across stable continental interiors, these rhinos inhabit a dynamic geological frontier. Earthquakes, ashfall, and tsunamis remain part of the environmental context. The species’ confinement intensifies the significance of each event. Geological probability now intersects with biological survival.

From a risk management perspective, natural hazard exposure increases extinction vulnerability. Conservation planning must incorporate seismic and volcanic data alongside demographic modeling. Unlike poaching, geological activity cannot be deterred through enforcement. Establishing a second population would reduce concentration risk but requires complex logistics. Until then, the species remains exposed to tectonic volatility.
On a broader scale, the Javan rhino exemplifies how anthropogenic range contraction magnifies natural hazard impact. When a species spans continents, disasters are localized. When confined to one seismic zone, disasters become existential. Evolutionary endurance now depends partly on plate movement stability. The species persists at the intersection of biology and tectonics.
