These video clips show recent activity at the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. Lava upwelling at the western vent flows into the lake, where bubbling is commonly present. In the eastern portion of the crater, a steep spatter cone has produced vigorous spattering and small lava flows.

USGS geologist Dan Dzurisin is near Sisters, in Central Oregon, to set up portable GPS monitoring equipment to track something that's been going on for 25 years and still goes on today. It’s uplift, a subtle rise in the ground’s surface, in an area west of South Sister volcano.

Volcano Awareness Month 2022 Deformation Update — Deformation at Hawai‘i’s volcanoes during 2021: The start of a new chapter
link2021 was an interesting year for deformation at both Kīlauea and Mauna Loa volcanoes. At Kīlauea, 2021 provided a glimpse of what the future might hold as the system recovers from the large collapses that accompanied the 2018 lower East Rift Zone eruption.

Mauna Loa is an active volcano, though it has been quiet for almost 30 years. An eruption is not imminent, but patterns of ground deformation on Mauna Loa over the past year may indicate that new, previously unobserved processes may have occurred. Mauna Loa lava flows have the capacity to disrupt lives and commerce throughout the Island of Hawai‘i.

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.

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.
