  • Volcanic Unrest in Hawaii and Alaska: Geologists Monitor Critical Minerals and Global Geological Shifts

    Volcanic Unrest in Hawaii and Alaska: Geologists Monitor Critical Minerals and Global Geological Shifts
    Dec 6 2025
    In the United States, geologists are closely watching Hawaii, where the US Geological Survey Hawaiian Volcano Observatory reports renewed inflation and gas driven tremor beneath the summit of Kilauea volcano on the Island of Hawaii. According to the observatorys December 5 daily update, lava remains visible in both the north and south vents within Halemaumau crater, with vigorous spattering and gushing gas flames indicating magma standing high in the conduit, and models suggest the next eruptive fountain episode, numbered thirty eight in the current sequence, is likely to begin between December six and eight. A December two monitoring overflight documented incandescent lava deep in the north vent and bright yellow native sulfur deposits forming around the vents as sulfur rich gases cool at the surface, underscoring the intense degassing that continues even between major outbursts, as shown in video released by the survey this week.

    Farther north in Alaska, the US Geological Survey and Volcano Discovery report that Great Sitkin volcano in the Aleutian arc continues its low level eruption, with slow lava effusion building a thick lava dome in the summit crater and occasional small explosions sending ash a short distance from the vent, a reminder that the North Pacific remains one of the most volcanically active air routes on Earth. These parallel activities at Kilauea and Great Sitkin fit into a broader global pattern summarized in the most recent Smithsonian Institution Global Volcanism Program weekly report, which lists twenty nine volcanoes worldwide with confirmed eruptions in the week ending December two, including frequently active systems such as Etna in Italy, Merapi in Indonesia, and Popocatepetl in Mexico, demonstrating that roughly forty to fifty volcanoes are typically in intermittent eruption at any given time.

    Beyond active volcanism, new research emerging this week in outlets such as Science Daily highlights how ancient geological records inform present day hazards. One study uses three point three billion year old zircon crystals to show that Earths early crust and mantle were far more dynamic than once thought, implying that modern style plate tectonics and the recycling of crustal material began very early in our planets history, which helps explain why todays continents host rich ore deposits, geothermal systems, and long lived fault zones. In the American Southwest, recent Geological Society of America communications on land subsidence in Arizonas Willcox Basin, driven by intensive groundwater withdrawal, are resonating with current concerns over how human activity is reshaping the geology of arid regions, effectively lowering land surfaces and subtly altering local seismic and flooding risk.

    In New Mexico, New Mexico Tech announced on December three that it and the state Bureau of Geology have received a two point five million dollar United States Department of Energy grant to establish a research hub for critical minerals, reflecting a strategic shift in United States geoscience toward locating, characterizing, and responsibly extracting elements like lithium, rare earth elements, and copper that are essential for renewable energy technologies and national security. Mining News North reports that United States Geological Survey leadership is simultaneously championing domestic exploration for these critical minerals, pointing to a newly updated 2025 national critical minerals list that now includes sixty minerals and materials considered vital to the economy and defense, a move that ties subsurface mapping, structural geology, and geochemistry directly to energy transition policy.

    Internationally, the Geological Society of London and partners hosted an early December conference on the global challenge of sand mining, emphasizing that sand, after water, is the planets most used resource and that unregulated extraction from rivers and coasts is reshaping landscapes, accelerating erosion, and altering sediment delivery to deltas. At the same time, upcoming meetings like the International Conference on Geology and Climate Change in Bukhara, Uzbekistan and the American Geophysical Unions annual gathering in New Orleans underscore how geologists are increasingly focused on how Earth processes, from volcanoes to groundwater depletion, interact with climate change, infrastructure, and resource demand, with research in the United States providing a significant share of the data and models guiding that global conversation.

  • Heightened Volcanic Activity and Shifting Subsurface Dynamics Across the United States

    Heightened Volcanic Activity and Shifting Subsurface Dynamics Across the United States
    Nov 29 2025
    Recent geological events across the United States reveal heightened volcanic activity and significant shifts in Earth's subsurface dynamics. Hawaii's Kilauea volcano remains at the center of attention, with Episode 37 of its ongoing Halemaʻumaʻu eruption beginning on November 25th. The eruption features sustained lava fountains approximately 400 feet in height erupting from the north vent, with fountain heights increasing rapidly. According to the Hawaiian Volcano Observatory, past episodes have produced incandescent lava fountains exceeding 1000 feet high that generate eruptive plumes reaching 20,000 feet above ground level. The observatory noted that winds are blowing from the northeast direction, suggesting volcanic gas emissions and material may distribute toward the southwest. Seismic tremor increased significantly before this episode began, and summit tilt switched from inflation to deflation. The aviation color code for Kilauea remains at Orange, indicating heightened volcanic activity.

    In the western continental United States, volcano monitoring networks detected important changes at multiple sites. California's monitored volcanoes including Mount Shasta show normal background earthquake activity and deformation patterns. Meanwhile, the Cascade Range experienced a shift when eruptive activity paused following the end of lava fountaining on Tuesday, November 25th. Scientists observed moderate glow from the south vent overnight along with tremor spikes suggesting gas pistoning at depth within the vents.

    Yellowstone Caldera in Wyoming presents a different geological story. According to the Yellowstone Volcano Observatory's November monitoring update, caldera activity remains at background levels with 180 located earthquakes in October, the largest measuring magnitude 3.7. Four distinct earthquake swarms occurred throughout the month, with one swarm near Mammoth Hot Springs producing 42 earthquakes during late October. More significantly, continuous GPS stations recorded the resumption of long-term subsidence in mid-October after the seasonal deformation signal ended. This subsidence has been ongoing since 2015, indicating Yellowstone's continued geological dynamism despite stable surface conditions.

    Beyond the continental United States, an undersea volcano near Oregon shows signs of impending eruption. Axial volcano's surface has ballooned to nearly the same height as it reached before its last eruption in 2015, a sign that magma has accumulated underground and built pressure. Scientists describe this development as a significant forecasting success, with increased seismic activity indicating moving magma beneath the seafloor.

    These concurrent volcanic and seismic events underscore the dynamic nature of North American geology and the critical importance of continued monitoring to understand Earth's evolving subsurface processes.

  • "Mapping Critical Minerals: U.S. Geological Survey's Nationwide Initiative"

    "Mapping Critical Minerals: U.S. Geological Survey's Nationwide Initiative"
    Nov 26 2025
    A major focus in recent United States geology news is the ongoing effort by the United States Geological Survey to better understand the nation’s critical mineral resources. As announced by the US Geological Survey earlier this week, thirteen states including Nevada, Montana, and Minnesota are participating in joint projects to map and inventory minerals found in both current and historic mine wastes. This initiative is designed to secure domestic sources of minerals essential for technology, defense, and energy industries. The United States Geological Survey also released updated assessments of oil and gas reserves in both the Phosphoria Total Petroleum System and the Niobrara Formation, underscoring the significant, still undiscovered energy potential in southwest Wyoming and northwest Colorado, with estimates exceeding a combined six trillion cubic feet of natural gas and more than 700 million barrels of oil.

    Recent headlines are highlighting an extraordinary discovery beneath the Appalachian Mountains. According to ScienceDaily, researchers have identified a colossal heat blob, a remnant of tectonic activity that split Greenland from North America about 80 million years ago, still migrating slowly beneath the United States. This finding offers new insights into the deep geologic history and mantle dynamics of the region, which may help explain seismic and geothermal anomalies observed along the Appalachians.

    In volcanic activity, the United States Geological Survey’s Alaska Volcano Observatory reported continued eruption at Great Sitkin Volcano in Alaska. While no significant ashfall on nearby communities was recorded, this ongoing eruption is closely monitored due to its potential impact on air travel and local ecology. Globally, the Kamchatka Peninsula’s Bezymianny volcano remains highly active, with significant eruptions sending ash plumes several kilometers into the atmosphere, as noted by Volcano Discovery.

    Significant sinking of land continues in Arizona’s Willcox Basin, according to the Geological Society of America. This phenomenon, known as subsidence, is linked to prolonged groundwater extraction and serves as a warning for other arid southwestern regions facing similar stress on aquifers.

    On the international stage, geology communities recently gathered at the International Professional Geology Conference in Spain, focused on advancing geosciences for planetary challenges like resource management and climate change. UNESCO’s General Conference also emphasized the role of geoparks and education in disaster risk reduction.

    Collectively, these new findings emphasize emerging patterns in American geology, including the critical need to balance resource extraction with long-term environmental stability, the importance of international scientific collaboration, and mounting attention to geologic hazards posed by both natural processes and human activity. Insightful advances in mapping deep Earth structures, tracking volcanic and seismic activity, and devising strategies for sustainable mineral exploitation remain central themes shaping the science of geology in the United States and beyond.
