On Sunday, a powerful eruption from Hawaii’s Kilauea Volcano hurled lava over 1,000 feet into the sky. The eruption occurred in Hawai‘i Volcanoes National Park, located about 200 miles southeast of Honolulu. The park is home to both Kilauea and Mauna Loa, the latter being the world’s largest active volcano.
According to the US Geological Survey (USGS), Kilauea stands at 4,091 feet and is one of the world’s most active volcanoes. Since December 23, lava has been steadily erupting from its Halemaʻumaʻu crater, now entering its 23rd episode.
Details of the May 25 Eruption
The USGS reported that on May 25, lava erupted from two vents inside Halemaʻumaʻu. The eruption lasted around six hours, with the south vent stopping at 10:25 p.m. and the north vent ending at 9:48 p.m. local time.
Health Hazards from Volcanic Gases
Authorities are concerned about elevated levels of volcanic gases such as sulfur dioxide (SO₂), carbon dioxide (CO₂), and water vapor, which can have serious health effects, especially downwind.
When sulfur dioxide reacts with the atmosphere, it forms a visible volcanic smog or “vog”, which may cause respiratory problems and other health issues for those exposed to it.
“Pele’s Hair” and Volcanic Debris
In addition to vog, volcanic debris such as lava fountains and Pele’s hair thin strands of volcanic glass pose further risks. These fibers can collect into tumbleweed-like formations and are known to irritate the skin and eyes.
Officials have advised visitors and locals to minimize contact with Pele’s hair and other debris, especially during strong winds, which can carry the particles beyond the eruption site.
