Breaking news - on 29 September 2021 a new eruption commenced at the Kīlauea summit. A new lava lake is forming in Halema'uma'u crater. Volcanic gases are continuously released during eruptions of Kīlauea volcano, resulting in the potential for vog, downwind. Ashfall and other lightweight volcanic glass fragments from the lava fountains (e.g. Pele's hair) 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.
