New! IVHHN Vog Dashboard has all the information you need about vog.
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 .
