Vog mostly affects the Kona coast on the west side of the Island of Hawaii, where the prevailing trade winds blow the vog to the southwest and southern winds then blow it north up the Kohala coast. Prolonged periods of southerly Kona winds , however, can cause vog to affect the eastern side of the Island on rare occasions, and affect islands ...
The 2018 lower Puna eruption was a volcanic event on the island of Hawaiʻi, on Kīlauea volcano's East Rift Zone that began on May 3, 2018. It is related to the larger eruption of Kīlauea that began on January 3, 1983, though some volcanologists and USGS scientists have discussed whether to classify it as a new eruption. [2]
The latest eruption of a Hawaii volcano isn't threatening any infrastructure but health officials are warning the public about air-quality hazards from volcanic smog known as vog. Kilauea, one of ...

In the mid-1980s, HVO launched the Big Island Map Project (BIMP) to update the geologic map of the island of Hawai'i. Its major publication is the 1996 Geologic Map of the Island of Hawai'i (1996) by E.W. Wolfe and Jean Morris, digitized in 2005.
A separate plant (Puna Geothermal Venture) went online in 1993 in Puna's Lower East Rift Zone and continued to generate 25–30 megawatts of electricity [11] The natural increase in hydrogen sulfide and volcanic ash emissions due to volcanic activity within the Kilauea caldera at times produces sufficient vog to affect breathing on the nearby ...
