Geologists say explosive event possible at Hawaii volcano

PAHOA, Hawaii (AP) — Geologists warned Wednesday that Hawaii’s Kilauea volcano could erupt explosively and send boulders, rocks and ash into the air around its summit in the coming weeks.

The U.S. Geological Survey said the risk will rise if the lava drops below the groundwater level beneath the summit’s caldera.

An influx of water inside could cause steam-driven explosions. There’s also potential for ash, steam and sulfur dioxide emissions.
