It's just the latest hazard from a weeks-old eruption that has so far generated earthquakes and featured gushing molten rock, giant ash plumes and sulfur dioxide. The eruption has destroyed more than 40 buildings forced more than 2,000 people to evacuate.

There has been continuous low-level ash emission from Kilauea's summit with larger explosions every few hours, said U.S. Geological Survey geophysicist Mike Poland. Two small eruptions happened late Monday afternoon and early Tuesday morning, producing ash clouds that did not reach the 10,000-foot (3,048-meter) level.
