Volcano producing toxic lava plume called ‘laze’

The eruption of Kilauea volcano in Hawaii sparked new safety warnings about toxic gas on the Big Island’s southern coastline after lava began flowing into the ocean and setting off a chemical reaction.

The molten rock started pouring into the sea over the weekend. It’s been generating plumes of lava haze or “laze” as it interacts with seawater.

It’s just the latest hazard from a weeks-old eruption that has so far generated earthquakes and featured gushing molten rock, giant ash plumes and sulfur dioxide. The eruption has destroyed more than 40 buildings forced more than 2,000 people to evacuate.

There has been continuous low-level ash emission from Kilauea’s summit with larger explosions every few hours, said U.S. Geological Survey geophysicist Mike Poland. Two small eruptions happened Monday afternoon and Tuesday morning, producing ash clouds that did not reach the 10,000-foot level.
