Hawai`i Volcanoes National Park
Current Sulfur Dioxide (SO2) and Particulate (PM2.5) Conditions
The map above indicates the approximate direction
and extent of the volcanic gas plumes (yellow wedges) from Halema'uma'u and
Pu'u O'o. Within the plumes are unhealthy concentrations of sulfur dioxide
(SO2) and small particles (PM2.5). Color-coded health advisories (color
circles or label boxes) are issued when the plumes affect surface areas.
 |
Sulfur dioxide gas plumes from volcanic vents may impact common visitor areas around the Kilauea caldera. Unhealthy to hazardous conditions may exist. Plan outdoor activities for safer areas. |
