Volcano Watch: Halemaʻumaʻu eruption reaches new heights as HVO updates Volcano Alert Notifications
Record-setting lava fountain and plume heights were reached during Episode 23 of the Kīlauea summit caldera eruption. Given increasing airborne hazards associated with each new eruptive episode, Hawaiian Volcano Observatory is changing its episode notification types.
Lava fountains reach 1,000 feet during Episode 23 of ongoing Kīlauea eruption
Lava fountains reach more than 1,000 feet, volcanic plume soars at least 5,000 feet before most recent phase of eruptive activity — that teased for several days — abruptly ends after just 6 hours and 10 minutes Sunday night.
New eruptive episode at Kīlauea produces lava fountains 650 feet high
The fountaining phase of the latest episode began at 3:20 a.m. this morning and lasted for 10 hours and 8 minutes.
Kīlauea summit eruption remains paused, but glow from lava lake persists
Summit tiltmeters on the Big Island volcano reversed from deflationary tilt to inflationary tilt at about the same time the lava fountain shut down Friday. Rapid change from deflation to inflation at the onset of each of the eruptive episodes suggests another episode could erupt in the coming days to weeks if summit magma chambers repressurize sufficiently.
DOH advises public to be mindful of air quality as Kīlauea erupts
As the eruption and volcanic gas emissions continue, downwind communities may be affected by vog conditions (hazy air pollution caused by volcanic emissions). Particulates in the air and levels of sulfur dioxide (SO2) may increase and fluctuate in various localized areas on Hawai‘i Island, causing poor air quality. Currently, air quality levels are elevated at the Ocean View and Pahala air quality monitoring stations.
Volcano Watch: Tracking down Mauna Loa’s carbon dioxide
Although the amount of CO2 emitted by Mauna Loa may be small in a global view, it could still yield important clues about Mauna Loa’s volcanic processes and future eruptions. HVO hopes to find a location for the new gas monitoring station soon and have it installed in the coming months.
UH study estimates vog, air pollution will hurt student test scores, especially on Big Island
A new University of Hawaiʻi collaborative study by a team of experts estimates vog (volcanic smog) will have detrimental impacts on student test scores, especially students on the Big Island.
Kīlauea Eruption Poses Air Quality Hazard With Increased Vog and SO2 Levels
Health officials say vog conditions and sulfur dioxide (SO₂) air levels may increase and fluctuate in various areas of the state.
Kīlauea Volcano Idle, Air Quality Clean and Clear
Hawaiʻi Tourism Authority executives say, “After 3 months of continuous lava flows,” they are “cautiously hopeful” the cessation in activity becomes permanent.
Voggy Skies from Days Gone By: Reviewing Kīlauea Volcano’s Gas Release
Many Island of Hawai‘i residents are familiar with the volcanic air pollution known as “vog.” The main culprit in the formation of vog is sulfur dioxide gas (SO2) released from Kīlauea’s eruptions.
Active Spattering at Fissures, Sulfur Dioxide Plumes Accumulate in Cloud Deck
The view from the Hawaiian Volcano Observatory overflight this morning showed calm winds with sulfur dioxide plumes rising and accumulating in the cloud deck.
20th Fissure Opens, Elevated Levels of Sulfur Dioxide
Hawaiian Volcano Observatory reports a new fissure has opened in the Lanipuna Gardens Subdivision northeast from fissure 19.
Steps Taken to Mitigate Risks to Puna Geothermal Venture
Expected steps include addressing supplies of pentane gas used in production of geothermal power including options for off-site relocation or controlled leakage or burn.
