PAHOA, Hawaii — White plumes of acid and extremely fine shards of glass billowed into the sky over Hawaii as molten rock from Kilauea volcano poured into the ocean, creating yet another hazard from an eruption that began more than two weeks ago: A toxic steam cloud.

Authorities on Sunday warned the public to stay away from the cloud that formed by a chemical reaction when lava touched seawater.

Further upslope, lava continued gushing out of large cracks in the ground in residential neighborhoods in a rural part of the Big Island. The molten rock made rivers that bisected forests and farms as it meandered toward the coast.

The rate of sulfur dioxide gas shooting from the ground fissures tripled, leading Hawaii County to repeat warnings about air quality. At the volcano’s summit, two explosive eruptions unleashed clouds of ash. Winds carried much of it toward the southwest.

Joseph Kekedi, an orchid grower who lives and works about 3 miles (5 kilometers) from where lava dropped into the sea, said the flow luckily did not head toward him. At one point, it was about a mile (asterisk)1.6 kilometers) upslope from his property in the coastal community of Kapoho.

Residents can only stay informed and be ready to get out of the way, he said.

“Here’s nature reminding us again who’s boss,” Kekedi said.

Scientists said the steam clouds at the spots where lava entered the ocean were laced with hydrochloric acid and fine glass particles that can irritate skin and eyes and cause breathing problems.

The lava haze called “laze” from the plume spread as far as 15 miles (24 kilometers) west of where the lava met the ocean on the Big Island’s southern coast. It was just offshore and running parallel to the coast, said U.S. Geological Survey scientist Wendy Stovall.

Scientists said the acid in the plume was about as corrosive as diluted battery acid. The glass was in the form of fine glass shards. Getting hit by it might feel like being sprinkled with glitter.

“If you’re feeling stinging on your skin, go inside,” Stovall said. Authorities warned that the plume could shift direction if the winds changed.

The Coast Guard said it was enforcing a safety zone extending 984 feet (300 meters) around the ocean entry point.

Coast Guard Lt. Cmdr. John Bannon said in a statement Sunday that “getting too close to the lava can result in serious injury or death.”

Gov. David Ige told reporters in Hilo that the state was monitoring the volcano and keeping people safe.

“Like typical eruptions and lava flows, it’s really allowing Madam Pele to run its course,” he said, referring to the Hawaiian goddess of volcanoes and fire.

Ige said he was thankful that the current lava flows did not pose a threat to homes and hoped it would stay that way.

On Saturday, the eruption claimed its first major injury when a man was struck in the leg by a flying piece of lava.

David Mace, a spokesman for the Federal Emergency Management Agency who was helping Hawaii County respond to the disaster, did not have further details about the man’s injuries or his condition.

Kilauea has burned some 40 structures, including two dozen homes, since it began erupting in people’s backyards in the Leilani Estates neighborhood on May 3. About 2,000 people have evacuated their homes, including 300 who were staying in shelters.

In recent days, the lava began to move more quickly and emerge from the ground in greater volume. Scientists said that’s because the lava that first erupted was magma left over from a 1955 erupted that had been stored in the ground for the past six decades.

The molten rock that began emerging over the past few days was from magma that has recently moved down the volcano’s eastern flank from one or two craters that sit further upslope — the Puu Oo crater and the summit crater.

The new lava is hotter, moves faster and has spread over a wider area.

Early Monday, a small eruption occurred at the Kilauea summit, producing an ash plume that reached about 7,000 feet (2,134 meters). Officials said wind carried the ash plume to the southwest, toward the communities of Wood Valley, Pahala, Naalehu and Waiohinu.

Scientists have said they do not know how long the eruption will last. The volcano has opened more than 20 vents, including four that have merged into one large crack. It has been gushing lava high into the sky and sending a river of molten rock toward the ocean at about 300 yards (274 meters) per hour.

Hawaii tourism officials have stressed that most of the Big Island remains unaffected by the eruption and is open for business.

(CNN) After earthquakes and molten lava tore open the earth in Hawaii, residents of the Big Island have new threats to worry about: acid rain and volcanic smog.

Sulfur dioxide gas and other air pollutants emitted from Kilauea volcano react with oxygen, atmospheric moisture and sunlight to produce volcanic smog and acid rain, according to the US Geological Survey.

Similar to battery acid

Such droplets turn into sulfuric acid, and have the corrosive properties of diluted battery acid.

The amount of acid rain depends on the concentration of sulfur dioxide in the air, Guy said.

“However, there is great uncertainty at this point how … big a risk acid rain is at this time,” he said. “There will be greater certainty in the coming days”

But he emphasized that while the effects of the acid rain on the skin are unclear, it’s been known to damage metal objects.

“When atmospheric moisture is abundant, these droplets combine with it and fall as acid rain, damaging plants and accelerating the rusting of metal objects such as cars, industrial and farm equipment, and building components,” the USGS said.

“When atmospheric moisture is abundant, these droplets combine with it and fall as acid rain, damaging plants and accelerating the rusting of metal objects such as cars, industrial and farm equipment, and building components,” the USGS said.

Acid rain can also affect rooftop rainwater-catchment systems, which Hawaii residents use for drinking water.

“In 1988, the drinking water of nearly 40% of homes using such systems in the Kona Districts of the island was found to be contaminated with lead leached by acid rain,” the USGS said. “Tests confirmed that the blood of some residents of these homes had elevated lead levels.”

In addition to acid rain, sulfur dioxide gas also causes hazy air pollution known as vog — volcano and smog.

“Wherever you have a vog plume, you’re going to have acid rain, if it’s raining,” University of Hawaii Meteorologist Steven Businger told CNN affiliate Hawaii News Now.

High concentrations of sulfur oxide emissions can cause acid rain, volcanic smog and air pollution, the USGS said.

The elderly, infants and those who suffer from respiratory conditions and cardiovascular disease are especially vulnerable to serious health effects of vog.

At higher concentrations, vog can cause headaches and irritation to the lungs and eyes, the University of Hawaii at Hilo said.

“For people with asthma and other respiratory problems, the effects are much more serious, causing a tightening of the airways in the lungs and making it very difficult to breathe,” the university said.

“There’s been no clear evidence that vog causes lingering damage to normally healthy individuals.”

The US Geological Survey says vog can affect human health and agriculture while acid rain can contaminate household water supplies by leaching metals from building and plumbing materials. But much is still unknown about vog’s composition and specifics on how it can affect health.

But Businger told the affiliate that acid rain is not an immediate health hazard, adding that it’s “the least of their (residents) worries.”

Army National Guard First Lt. Aaron Hew Len takes measurements for sulfur dioxide gas at volcanic fissures in the Leilani Estates neighborhood.

More vents

Dangers still persist, not only in the form of lava, but also earthquakes and newly formed cracks.

Two additional volcanic vents erupted Tuesday, leading to new evacuation orders on the island’s southeastern corner, where all 1,700 residents have been asked to leave. At least 36 structures have been destroyed.
