Vog Hazards Links
Halemaʻumaʻu’s plume changes from day to day, and wind direction changes periodically. You can deduce where the plume will be by noting the wind direction; the National Weather Service provides a week-long forecast of wind conditions.
The best course of action is:
- Have a supply of materials readyfor future events (baking soda, dust masks, respirators, and an emergency evacuation kit)
- Plan where you would go (friends, relatives) in case the plume was so thick that your health was threatened
- Keep apprised of current conditions at Halemaʻumaʻu by visiting the USGS-HVO update page.
