Hawaii volcano: Dangerous sulfur dioxide may cause ‘inability to breathe’


Dangerous levels of the toxic gas are rising from some fissures, or cracks in the ground caused by the volcano, Hawaii County officials said.

“Severe conditions may exist such as choking and inability to breathe,” the county’s civil defense agency said. “This is a serious situation that affects the entire exposed population.”

Officials warned residents to leave the area and get medical attention if they’re affected by the gas.

Since the Kilauea volcano erupted May 3, it’s been one nightmare after another for residents in the southeast part of the Big Island.

‘It sounded like hammers in the dryer’

At least 19 fissures have cracked open since Kilauea volcano erupted, purging lava and sulfur dioxide from deep underground.
A fissure spews lava in Pahoa, Hawaii, after a massive eruption of the Kilauea volcano.

Fissure 17 is the most active, shooting lava like a fountain and “sending spatter more than 100 feet into the air,” the Hawaiian Volcano Observatory said.

CNN’s Stephanie Elam said her heart started pounding as she approached one fissure.

“It sounded like hammers in the dryer,” she said. “The molten rock was such a deep vibrant orange that it looked technically altered. When the sulfur dioxide hit my lungs once, it took my breath away.”

The lava from Kilauea may get hotter and spew farther
The Hawaii State Department of Health is asking the general public to avoid any area with fissures because the gases emitted require special cartridge respirators.
Nina Bersamina heeded warnings to evacuate, saying residents are at the mercy of Pele, the Hawaiian goddess of fire.

“When you move to this volcano, or move to this island, you move into her house,” Bersamina said.

More eruptions could follow

Scorching lava has already swallowed dozens of homes and vehicles. So far, at least 37 structures have been destroyed, and counting.

In addition to the lava and toxic gases, now there are concerns about phreatic eruptions.
Those are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits, the US Geological Survey says. The intense heat may cause that water to boil and result in eruptions.

The lava lake in the crater has been dropping since May 2, which increases the chances for a phreatic explosion.

USGS officials said a phreatic eruption could happen at Halemaumau crater at the top of the Kilauea volcano. And it could send ash plumes as far as 12 miles from the summit crater, the Hawaiian Volcano Observatory said.

But it will be difficult to warn residents who may be in the path of such an eruption.

Janet Babb, a geologist from the volcano observatory, said phreatic eruptions are “notoriously hard to forecast, and can occur with little or no warning.”
