During a monitoring overflight of the Kīlauea summit on June 22, 2023, Hawaiian Volcano Observatory scientists briefly stopped on the Halema‘uma‘u crater floor to collect a lava sample. Afterward, they departed via helicopter with a low-angle view of the recent eruption area from the east.

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...

Growth of a passive lava lake during the 2020–2021 eruption of Kīlauea volcano, Hawaii Growth of a passive lava lake during the 2020–2021 eruption of Kīlauea volcano, Hawaii
We investigate the growth of a passive lava lake in Halemaʻumaʻu crater during the December 2020 to May 2021 eruption of Kīlauea volcano, Hawaii. Fed by vents above their surfaces, the formation of passive lava lakes in topographic lows is an important process in the growth of basaltic volcanoes. We captured visible and thermal images during 17 helicopter overflights and applied...

Island of Hawaiʻi eruptions 2018–present: Profound landscape and human impacts Island of Hawaiʻi eruptions 2018–present: Profound landscape and human impacts
This three-day field trip examines deposits and landscape evolution associated with recent eruptions of Kīlauea and Mauna Loa, Hawai‘i, USA, beginning with the lower East Rift Zone eruption and associated partial caldera collapse during the summer of 2018. As of this writing, there have been five eruptions within Kīlauea’s summit caldera, one eruption in the Southwest Rift Zone of...

Eruption of stagnant lava from an inactive perched lava lake Eruption of stagnant lava from an inactive perched lava lake
Lava flow hazards are usually thought to end when the erupting vent becomes inactive, but this is not always the case. At Kīlauea in August 2014, a spiny ʻaʻā flow erupted from the levee of a crusted perched lava lake that had been inactive for a month, and the surface of the lava lake subsided as the flow advanced downslope over the following few days. Topography constructed from...

Lava effusion rate evolution and erupted volume during the 2018 Kīlauea lower East Rift Zone eruption Lava effusion rate evolution and erupted volume during the 2018 Kīlauea lower East Rift Zone eruption
The 2018 eruption on the lower East Rift Zone of Kīlauea Volcano produced one of the largest and most destructive lava flows in Hawai’i during the past 200 years. Over the course of more than 3 months, twenty-four fissures erupted, and the rate of lava effusion varied by two orders of magnitude, with significant implications for evolving flow behavior and hazards. Syn-eruptive data were...

Submarine lava deltas of the 2018 eruption of Kilauea volcano Submarine lava deltas of the 2018 eruption of Kilauea volcano
Hawaiian and other ocean island lava flows that reach the coastline can deposit significant volumes of lava in submarine deltas. The catastrophic collapse of these deltas represents one of the most significant, but least predictable, volcanic hazards at ocean islands. The volume of lava deposited below sea level in delta-forming eruptions and the mechanisms of delta construction and...

Monitoring network changes during the 2018 Kīlauea Volcano eruption Monitoring network changes during the 2018 Kīlauea Volcano eruption
In the summer of 2018, Kīlauea Volcano underwent one of its most significant eruptions in the past few hundred years. The volcano’s summit and East Rift Zone magma system partially drained, resulting in a series of occasionally explosive partial caldera collapses, and widespread lava flows in the lower East Rift Zone. The Hawaiian Volcano Observatory (HVO) operates a robust permanent...
