UH Manoa Vog Measurement and Prediction project (VMAP) Volcanic gas and particulate data and forecast. Uses volcanic gas emission rates and wind field data to model and predict the concentration and dispersion pattern of volcanic SO 2 and sulfate particles.

The Hawaii Department of Health reports that vog conditions may increase and fluctuate in various areas of the state as volcanic activity on Hawaii Island continues. Vog is a hazy mixture of sulfur dioxide gas (SO 2 ) and fine particles (PM 2.5 ) emitted from an erupting volcano.

Oct 3, 2017 · Vog is the term that refers to the hazy air pollution caused by volcanic emissions from Kilauea Volcano on Hawaii (Big) Island. Think of it as volcanic smog, composed of carbon dioxide, sulfur dioxide, water vapor and fine acid particles.

In Hawaii, the gas plumes of Kīlauea rise up from three locations: Halemaʻumaʻu, Puʻu ʻŌʻō, and from along the coastline where lava flows from the East Rift zone enter the ocean. The plumes create a blanket of vog that can envelop the island.

Dec 28, 2024 · The University of Hawaii (UH) Vog Model shows that SO2 emissions have mostly cleared out of the smaller islands and should remain confined to portions of the Big Island and the waters to the ...

Vog Measurement and Prediction Project (VMAP) The University of Hawaii uses volcanic gas emission rates and wind field data to model and predict the concentration and dispersion pattern of volcanic SO2 and sulfate particles. Provided by the University of Hawaii at Manoa’s School of Ocean and Earth Science Technology. Hawaii SO2 Short Term ...

Mar 1, 2025 · The greatest concentrations of volcanic haze (vog) remain confined to Maui County and leeward Big Island but recent GOES GeoColor daytime imagery did depict haze creeping into eastern Oahu late...

The International Volcanic Health Hazard Network (IVHHN) has a new resource for the current eruptive activity and associated hazards at Kīlauea Volcano's lower East Rift Zone and summit. Find it at https://vog.ivhhn.org.
