(AP) — Lava from the Kilauea volcano oozed over two wells at a geothermal power plant on Hawaii’s Big Island, but county officials say the flow has stopped.

Officials say there was no release of any dangerous hydrogen sulfide gas after lava crept over the plugged wells Sunday.

Some feared a breach if lava penetrated the well shafts that tap steam and hot water to make electricity. Both wells were closed and secured in anticipation of the lava flow.
