U.S. Geological Survey's Hawaiian Volcano Observatory perched on the rim of Kīlauea Volcano's summit caldera, Hawai‘i

Close view of the USGS Hawaiian Volcano Observatory (right, with viewing tower) and National Park Service Jaggar Museum and overlook (left) on Kīlauea Volcano's caldera rim. At least three fault blocks can be seen below the observatory, which developed when Kīlauea's summit collapsed about 500 years ago to form the present-day caldera.

This section of Crater Rim Drive in Hawai‘i Volcanoes National Park was closed in February 2008 because of the high concentration of volcanic gas blowing across the road from Halema‘uma‘u Crater by prevailing trade winds. The concentration of sulfur dioxide gas in this area is considered hazardous to human health.

Volcanic air pollution, commonly called volcanic smog or vog, at the summit of Kīlauea Volcano created by the gas plume rising from Halema‘uma‘u Crater during slack tradewinds. High vog levels result in regionally hazy sky conditions that degrade air clarity and reduce visibility for everyone.
