Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions
In 2012, the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) installed an array of zenith-pointing ultraviolet spectrometers to track gas emissions from summit of Kīlauea (Businger et al., 2015; Elias et al., 2018). The instruments are arranged in an arc perpendicular to the dominant trade-wind direction approximately 2 kilometers (km) southwest of the actively degassing...
Timelapse and webcam images of the 2022 eruption of Mauna Loa, Island of Hawaiʻi Timelapse and webcam images of the 2022 eruption of Mauna Loa, Island of Hawaiʻi
The 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi, was the first eruption on the volcano since 1984, producing a 17 km lava flow that threatened a major highway (Mulliken and others 2024; Zoeller and others 2024). The eruption began with lava fountaining in the summit caldera (Mokuʻāweoweo) at 23:21 HST on November 27, transitioning to vents on the Northeast Rift Zone (NERZ) by...
