Question: Does vog reach every main island in the State of Hawaii?
Answer: Yes. Although volcanic emissions from the Kilauea volcano (located on the Big Island) and wind patterns are unpredictable, I can provide a basic understanding of how each of Hawaii's main islands are affected by that substance:
Vog is common in these locations:
- Big Island - West
Vog is uncommon in these locations:
- Big Island - East
- Lanai
- Mauai
- Molokai
- Oahu
Vog rarely reaches these locations:
- Kauai
- Niihau
Vog is uncommon or rare in those locations because Hawaii's normal northeast trade winds either blows Kilauea's vog out to sea, and/or to the western part of the Big Island, but abnormal prolonged periods of southerly winds can blow that substance to the rest of the island chain.
