Explosive steam could erupt at the summit of a volcano on Hawaii, hurling rocks and ash miles into the sky, say geologists.
The warning came as steam and lava were reported from an 18th fissure caused by Kilauea volcano on Hawaii’s Big Island, with evacuations ordered.
The 18th fissure opening came after two others opened on Saturday.
Plant workers last week removed 50,000 gallons of pentane stored at the Puna Geothermal Venture plant site as a precaution.
