An HVO scientist clears tephra from a solar panel during the September 2021 Kīlauea summit eruption

An HVO scientist clears tephra from a solar panel during the September 2021 Kīlauea summit eruption. A glove is used to brush away the Pele’s hair and other fine volcanic glass fragments to avoid small cuts and splinters. While working within the closed high-hazard area at Kīlauea summit within Hawaiʻi Volcanoes National Park, hardhats are used to protect the wearer from falling tephra. Gas masks are worn around the neck for quick protection if volcanic gas concentrations escalate or the wind shifts suddenly, even during non-eruptive periods. HVO access to the closed area is by permission from, and in coordination with, HVNP. USGS photo.
