The 1883 Krakatoa eruption was so powerful it generated pressure waves recorded around the globe and caused tsunamis that killed over 36,000 people.
Ujung Kulon National Park sits directly across the Sunda Strait from Anak Krakatau, the active volcanic island formed after the 1883 Krakatoa eruption. Geological records show that Krakatoa-triggered tsunamis have devastated coastlines in this region before. In December 2018, a partial collapse of Anak Krakatau generated a tsunami that struck nearby shores without warning. Much of the Javan rhino habitat lies in low-elevation coastal forest vulnerable to similar wave surges. With fewer than 80 individuals concentrated in this area, even localized flooding could remove a significant fraction of the species. Unlike widespread species that can recolonize, Javan rhinos have no secondary population to buffer catastrophic loss. Conservation assessments explicitly list natural disaster as a primary extinction risk. The species’ fate is therefore partially tied to tectonic forces beneath the Sunda Arc.

This creates a rare conservation paradox: the park that saved the species also concentrates its vulnerability. Ujung Kulon’s isolation protects rhinos from poaching, yet it amplifies exposure to geophysical risk. Disaster mitigation strategies, including early warning systems and habitat zoning, have limited utility against sudden volcanic flank collapse. Establishing a second population elsewhere in Indonesia has been proposed, but identifying sufficient habitat free from human encroachment is politically and ecologically complex. Translocation would require moving some of the most endangered large mammals on Earth. A miscalculation could reduce breeding success or trigger fatal stress responses.
The broader implication is that extinction risk in the 21st century is no longer driven only by hunting or habitat clearing. It now includes probabilistic geophysical events interacting with human-induced range contraction. The Javan rhino has effectively become a species dependent on volcanic stability. Its survival depends on seismic quiet as much as ecological management. Few conservation stories intertwine so directly with plate tectonics. The margin between continuity and extinction can be measured in meters of elevation.
