A Boston-area man hoping to get an up-close view of the Kilauea eruption at Hawaii Volcanoes National Park was injured after falling off a cliff in the dark, a National Park Service spokesperson said.

A tree ultimately broke his fall, saving the man from an additional, potentially fatal, 100-foot fall to the caldera floor

One of the world’s most active volcanoes, Kilauea on Hawaii’s Big Island, began spewing lava from the north vent Wednesday, the latest event in an ongoing eruption that began almost six months ago. Lava fountains reached heights of more than 330 feet (100 meters) and feeding multiple lava streams.
