The world’s only population of Javan rhinoceros, already under severe threat from poaching, could go extinct in the future due to natural disasters, including volcanic eruptions and tsunamis, according to a new study published in Conservation Letters. The few remaining Javan rhinos live in Ujung Kulon National Park, which is within sight of volcanic Mount Krakatoa and close to the Indonesian Sunda Arc, an area of converging tectonic plates that commonly cause earthquakes, triggering tsunamis.
