Lava in Hawaii has crept towards a geothermal power plant forcing the workers to shut down facilities due to fears of deadly gases.
Flowing lava has been seen from the Kilauea Volcano, and workers in the nearby power plant have removed flammable substances and the deep-underground wells have been filled with cold water.
If the lava flows into the wells before they’re plugged, it could release lethal Hydrogen sulphate gas.
