Volcanic gases rise from the Kilauea lava flow near #Pahoa, Hawaii, on Monday. Scientists say higher sulfur dioxide emissions recorded at the #volcano's vents in recent days are creating the potential for heavier than usual #vog, or volcanic smog. So far, trade winds have been mostly blowing the gray haze offshore.

Volcanic smog, or air pollution, is created by vapor, carbon dioxide and sulfur dioxide gas released from #Kilauea. It reacts in the atmosphere with oxygen, sunlight, moisture and other gases and particles. In a matter of hours or days, it converts to fine particles that scatter sunlight, creating a haze that can be seen downwind of Kilauea.
