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.

In the winter of 2015, the public noticed thousands of dead seabirds washing ashore across the western coast of the United States and Canada. The USGS linked this massive seabird die-off to the North Pacific Marine Heatwave. A marine heatwave occurs when sea surface temperatures are above normal for an extended period of time.

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.

Developing divergent, plausible, and relevant climate futures for near- and long-term resource planning
linkIt seems the effects of climate change were all too clear in 2021. Yet, we know more change is expected. When trying to adapt to a changing climate, with all the inherent uncertainties about how the future may play out, resource managers often turn to scenario planning as a tool.

The tallest volcano on the Galapagos Islands began erupting on January 6. The eruption sent lava flows down the mountainside and ash skyward. Like the Hawaiian Islands, the Galapagos are volcanic islands formed over an active hotspot. Wolf Volcano last erupted in May and June of 2015.

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.

Recent activity has altered the landscape in northwestern China. Alluvial Fan, from the second Earth As Art collection, was acquired in 2002 by the ASTER sensor on NASA’s Terra satellite. It’s truly a fan favorite, often named one of the top images of the entire collection.

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.

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.
