Residents near Hawaii's Kilauea volcano faced warnings on Monday that more lava-spewing fissures could open near their homes and that the volcano's summit may be getting ready for an explosion that could scatter ash and debris for miles.
Since Kilauea began erupting on May 3, nearly 2,000 people have been ordered to evacuate as 18 giant fissures ripped through the area, including two new ones that opened on Sunday with ear-piercing screeches that sent lava and rocks flying.
But the U.S. Geological Survey also has warned that pent-up steam could cause an explosion at the top of the volcano as the pool of lava recedes, launching a 20,000-foot (6,100-meter) plume that could spread debris over 12 miles (19 km).
