Volcano Watch: Halemaʻumaʻu eruption reaches new heights as HVO updates Volcano Alert Notifications
Record-setting lava fountain and plume heights were reached during Episode 23 of the Kīlauea summit caldera eruption. Given increasing airborne hazards associated with each new eruptive episode, Hawaiian Volcano Observatory is changing its episode notification types.
Volcano Watch: Determining magma storage depths at Kīlauea
By measuring the density of carbon dioxide trapped in bubbles formed in crystals as magma is under pressure underground, scientists can determine the depth at which the gas became trapped, and hence the depth of magma storage before eruption.
Land managers receive funds to support climate change resilience
The Carbon Smart Program has awarded a total of $1,000,000 to 10 grantees to develop and implement plans for regenerative sustainable practices, particularly carbon sequestration (capturing, securing and storing carbon dioxide from the atmosphere). The program is a pilot initiative to promote the preservation and enhancement of ranches, forests and farmlands in Hawaiʻi,

UH: Rainfall increases oceanic carbon sink by 6%, study shows
The ocean absorbs about a quarter of carbon emitted by human activities, but rainfall is responsible for about 6% of the ocean’s uptake of carbon dioxide (CO2), a new study found.
Volcano Watch: Tracking down Mauna Loa’s carbon dioxide
Although the amount of CO2 emitted by Mauna Loa may be small in a global view, it could still yield important clues about Mauna Loa’s volcanic processes and future eruptions. HVO hopes to find a location for the new gas monitoring station soon and have it installed in the coming months.
