Volcano Awareness Month 2022 Short Feature — HVO’s ongoing recovery from the 2018 Kīlauea events
linkCommunities on the Island of Hawai‘i continue to recover from Kīlauea’s 2018 lower East Rift Zone eruption and summit collapse as does the USGS Hawaiian Volcano Observatory (HVO). During the events of 2018, HVO instruments were lost, monitoring infrastructure was impacted, and HVO staff had to evacuate the observatory, which was damaged beyond repair.

Volcano Awareness Month 2022 Volcanic Gas Update — The ups and downs of Kīlauea’s gas emissions in 2021
linkIncredibly high sulfur dioxide (SO2) emission rates were measured during the lower East Rift Zone of Kīlauea in 2018—nearly 200,000 tonnes per day. Emissions dropped to only about 30 tonnes per day during Kīlauea’s non-eruptive quiet period from 2018–2020.

Volcano Awareness Month 2022 Seismology Update — 2021: A year of earthquake activity on the Island of Hawai‘i
linkThe last year has been a busy one for seismologists at the USGS Hawaiian Volcano Observatory. Earthquake activity at Kīlauea summit has varied over the past year, with upticks in a variety of seismic signals providing clues to the start of the December 2020 and September 2021 Kīlauea summit eruptions.

Volcano Awareness Month 2022 Geology Update — Kīlauea erupts after more than two years of quiet—twice!
linkFollowing the lower East Rift Zone eruption and summit collapse of Kīlauea in 2018, the volcano remained quiet for more than two years. Lava returned to Kīlauea in December 2020, boiling off the water lake that had been present at the base of Halema‘uma‘u crater, and starting a five-month long eruption in Hawai‘i Volcanoes National Park.

Eruptive activity resumed today in Halema‘uma‘u crater, at the summit of Kīlauea volcano, after a brief pause of several days. This video shows spattering and lava effusion from the west vent, which has built a steep spatter cone.

Structure-from-motion techniques use photographs taken from different angles to reconstruct the three-dimensional shape of an object. At Kīlauea, this technique has been used to rapidly generate maps of eruption activity from aerial imagery, allowing scientists to quantify changes over time such as the volume of lava erupted and surface area covered by lava.

Lava continues to erupt from the west vent in Halema‘uma‘u, and supply the lava lake through a spillway in the spatter cone. On November 12, a small overflow of the perched lava lake levee was visible from the western crater rim. Overflows are an important process for building up perched levees, as they help add height and stability.
