Lava from the Kilauea volcano in Hawaii has crept towards a geothermal power plant, prompting workers to shut down facilities amid fears of deadly gases.
Workers removed flammable substances and the plant's deep underground wells have been filled with cold water.
They will be plugged with iron.
If lava flows into the wells before they are plugged, it could release lethal hydrogen sulphate gas.
The slow‑moving lava has entered the plant site but has since stalled.
Emergency workers at the plant transported 60,000 gallons of highly flammable pentane gas out of the facility as a precaution.
