Hawaii Interagency Vog Information Dashboard

Welcome to the Vog Dashboard. Please click on the links below to find comprehensive information and data related to vog and its impacts.

Breaking news - on 20 December 2020 a new eruption commenced at the Kīlauea summit. The water lake has boiled away and multiple fissures opened in the caldera, erupting lava. Volcanic gases are continuously released during eruptions of Kīlauea volcano, resulting in the potential for vog, downwind. Ashfall presently represents a minor hazard, but visitors to Hawai‘i Volcanoes National Park should be aware that, if trade winds are absent, ashfall and elevated concentrations of SO2, at publically accessible areas of the summit, are possible. Follow eruption updates at https://www.usgs.gov/volcano/volcano-updates or on social media https://www.usgs.gov/volcano/social-media. Please also see the State of Hawaii Department of Health's news release.
