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.

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

Alaska Science Center geologist Doug Kreiner and University of Alaska, Fairbanks professor Sean Regan discuss the district-scale geology with the chief exploration geologist at Pogo Mine. This is a new collaborative study with USGS, UAF and Pogo Mine, to collaborate on unraveling the genesis of Pogo, an important producer of gold in Alaska with critical mi

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.

HVO scientists continue their survey of Kīlauea caldera floor, including the down-dropped block, for diffuse volcanic gas emissions. This photo shows a large crack, on a portion of the caldera floor that subsided in 2018, that is emitting volcanic gas and steam.

Stacked lava flows are visible in the wall of the down-dropped block, which was exposed during the Kīlauea summit collapse events in 2018. A small exposure of lighter-colored volcanic ash, likely the Keanakāko‘i tephra deposits erupted during Kīlauea's last explosive phase several hundred years ago, is visible beneath tens of meters (yards) of lava flows.

Eruptive activity paused within Halema‘uma‘u, at Kīlauea's summit, a bit more than 2 months ago. In that time, the spatter cone at the western fissure complex has slowly degraded due to numerous small scale collapses, leaving a debris apron (fresh looking rubble) and exposing the interior of the spatter cone.

A view looking north into Halema‘uma‘u on July 30, 2021. Although eruptive activity has paused at the summit of Kīlauea, HVO geologists still monitor the lava lake and summit area weekly. Lava lake surface depths remain the same since mid to late May when active lava was last observed at the surface. USGS photo by N. Deligne.
