Due to the dangerous nature of this event, visitors should NOT attempt to get close to or view lava flows in the active area. Please keep the roads clear to allow Civil Defense and residents to conduct their evacuations and necessary duties. The FAA has also closed the airspace overhead, so please be understanding if helicopter tours will not fly nearby.
Please note that the only really affected area is the southeast side of the island of Hawaii, AKA The Big Island. If you are flying into either Hilo or Kona, you are not likely to be affected by this event, so long as you are not driving down to Puna. Please check the maps linked above for an idea of where Hilo and Kona are relative to Puna. If you are sensitive to air quality, you may wish to check https://airnow.gov/index.cfm?action=airnow.local_state&stateid=12&tab=0 and http://weather.hawaii.edu/vmap/. Kona is far more likely to experience any air quality issues, due to the way tradewinds travel across the islands.
