The Hawai‘i Department of Health (DOH) is advising residents and visitors to remain cautious of air quality impacts following the early morning eruption of Kīlauea Volcano within Hawai‘i Volcanoes National Park.
The eruption, which began at approximately 2:20 a.m., has stabilized within the summit crater and poses no immediate threat to lives or infrastructure, according to the U.S. Geological Survey (USGS). The volcano alert level has been downgraded from Warning to Watch. However, the eruption continues to emit significant volcanic gases, including sulfur dioxide (SO₂), which may lead to vog (volcanic smog) and fluctuating air quality in downwind communities such as Ocean View and Pāhala.
Public Safety Measures
The DOH urges the public to take the following steps to protect themselves during periods of poor air quality:
- Limit Outdoor Activities: Avoid outdoor exercise and reduce activities that cause heavy breathing, particularly for sensitive groups such as children, the elderly, and individuals with respiratory or heart conditions.
- Keep Medications Accessible: Those with asthma or chronic respiratory issues should have prescribed medications on hand and take them as directed.
- Stay Indoors: Close windows and doors, and set air conditioners to recirculate air.
- Avoid Face Masks for SO₂: Standard masks like surgical, cloth, KN95, or N95 do not protect against volcanic gases but may help reduce exposure to particulates such as ash or Pele’s hair.
- Stay Hydrated: Drink plenty of fluids to avoid dehydration.
- Avoid Smoking: Steer clear of smoking and second-hand smoke.
- Prepare Emergency Plans: Ensure family plans are ready for any potential escalation of volcanic activity.
Resources for Real-Time Information
Residents and visitors are encouraged to use these resources to stay informed:
- Hawai‘i Interagency Vog Information Dashboard (www.ivhhn.org/vog/)
- Hawai‘i Ambient Air Quality Data (health.hawaii.gov/cab/hawaii-ambient-air-quality-data/)
- USGS Kīlauea Volcano Updates (www.usgs.gov)
Health Considerations
Those experiencing respiratory difficulties should contact their healthcare provider promptly, as symptoms may escalate quickly in areas with high SO₂ or vog exposure.
The DOH and other agencies continue to monitor the situation closely and will provide updates as conditions evolve. Residents are reminded to follow guidance from county and state emergency management officials.
