Fumes (volcanic gases) are hazardous to everyone's health. Visitors with heart or breathing problems and infants, young children, and pregnant women are especially at risk and should avoid being in areas where fumes persist.
The eruptive vents in Halema'uma'u Crater, Sulphur Banks, and Puʻu 'Ōʻō vent generate high levels of gases that may affect visitors - even those visitors who are healthy.
Concentrations of these gases is often dependent on wind direction. Hawaiʻi's normal tradewind pattern generally blows gases, emitted from the two main vents on Kīlauea, away from most visitor areas. However, even on a tradewind day, fumes from Puʻu ʻŌʻō and Halemaʻumaʻu may cross a roadway or linger in other areas of the park. In this event, close your car windows and run the air conditioning on recycled air and leave the area.
There are times when the park will close due to high levels of volcanic gases. Be flexible - Closures are initiated for visitor and employee safety. Air Quality Monitor
