 The gas plumes of the Kīlauea Volcano create a blanket of vog which the dominant trade winds mostly deflect toward the Kona coast on the west side of the island of Hawaiʻi.Vog contains chemicals that can damage the environment and the health of plants, humans, and other animals.Most of the aerosols are acidic and of a size where they can remain in the lungs to damage them and impair function.
