A 33-year-old Hawaii man is dead after entering a closed section of Kīlauea caldera at Hawaiʻi Volcanoes National Park, triggering an overnight search and rescue operation in steep, hazardous terrain, officials said.

In December, two trespassers were caught on camera hiking dangerously close to an active eruption inside a restricted zone of the park. The Hawaiian Volcano Observatory leaving Byron Ledge Trail in an attempt to get closer to erupting lava. A tree broke his fall and likely prevented him from plunging another 100 feet to the caldera floor, according to the National Park Service.
