Spatter ramparts from the April 30, 1982, Kīlauea summit eruption remain visible on the floor of Kīlauea caldera. During this brief eruption, which lasted approximately 19 hours, lava erupted from a 1-km-long (0.6 mile) fissure that extended to the northeast of Halema‘uma‘u.

During the gas survey of Kīlauea caldera, HVO scientists walk transects in a grid-like pattern. As they traverse, the MultiGAS instruments that they are carrying on their backs measure the amount of carbon dioxide (CO₂), sulfur dioxide (SO₂), water vapor (H₂O), and hydrogen sulfide (H₂S).

From the northwest corner of the largest down-dropped block within Kīlauea caldera, HVO scientists were able to spot the southern edge of the lava lake that was recently active, from December 2020 to May 2021. The ongoing Kīlauea caldera gas survey is being conducted with permission from Hawai‘i Volcanoes National Park.

On Tuesday, August 10, HVO scientists traversed the west and south rims of Halema‘uma‘u, at the summit of Kīlauea, to collect photos of the inactive lava lake from many different angles. Such a collection of photos will enable the construction of a three-dimensional model of the crusted lake surface using structure-from-motion software.

An anchor station in 20m water depth with a wave buoy and smart mooring attached. This instrument will deliver high-fidelity, real-time wave, water level, and wind data to scientists at the USGS St. Petersburg Coastal and Marine Science Center.

In recent weeks, HVO geophysicists have been undertaking a Global Positioning System (GPS) campaign across Kīlauea.

RestoreNet is partnering with the Gornish lab at the University of Arizona to better understand how a plant’s source location (provenance) influences its performance in a restoration setting. This greenhouse experiment will be conducted by PhD student, Sierra Lauman.

Schematic displaying the general processes associated with collapse of Yellowstone Caldera.  (A) Pre-caldera volcanism includes the eruption of dome complexes from the underlying magma chambers.  (B) The caldera-forming eruption evacuates a significant amount of magma from the chamber, causing the overlying crustal block to subside into the void space.&nbs

A novel stereo CoastCam will be installed on at dune at Pea Island for the duration of the experiment.

Over the past few months, HVO geophysicists have been conducting the annual high-precision Global Positioning System (GPS) survey of Kīlauea. The annual survey supplements HVO's continuous GPS monitoring stations and provides information on vertical and horizontal deformation of the ground surface.
