    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.

    "Uncovering America's Critical Mineral Needs: Geologists Tackle Supply Chain Challenges"
    Nov 15 2025
    In recent days, geology in the United States has taken the spotlight with the U.S. Geological Survey publishing its final 2025 list of critical minerals on November sixth. This list identifies sixty minerals deemed essential for the nation’s economy and security, with a focus on potential supply chain disruptions. According to the U.S. Geological Survey, new additions to the list include boron, copper, lead, metallurgical coal, phosphate, potash, rhenium, silicon, silver, and uranium. The update reflects new data, feedback, and changing industrial and geopolitical needs. Mineral security has become increasingly significant as rare earth elements, vital for smartphones, hard drives, and advanced defense systems, continue to be largely imported.

    This renewed attention on critical minerals comes as researchers highlight the need to develop more domestic sources and reduce dependency on imports. The U.S. Geological Survey emphasizes that rare earth elements could cause the highest cost to the American economy if their supply is disrupted. American Critical Minerals, an industry group, welcomed the inclusion of potash and lithium due to their importance for fertilizers and batteries.

    Continuing in geological developments, the summit eruption at Kīlauea in Hawaii remains active. The Hawaiian Volcano Observatory reported that by November thirteenth, the eruption had reached thirty-six episodes of lava fountaining since it began in December of last year. These ongoing volcanic events allow scientists to study eruption dynamics and gas emissions, informing not only local hazard assessments but also global models of volcanic activity.

    Elsewhere, landmark geology research was highlighted in reports from ScienceDaily. On November fourteenth, researchers in Greenland used advanced fiber-optic technology to track how iceberg calving produces hidden underwater waves. These waves rapidly melt glacier faces and are reshaping our understanding of ice loss and rising sea levels. Meanwhile, scientists in Antarctica recently analyzed six million-year-old ice, providing the oldest direct record of Earth’s ancient atmosphere and climate. This discovery details dramatic cooling trends and offers vital clues to greenhouse gas variations over the ages.

    Seismic activity continues to be a pressing topic. ScienceDaily notes new research into the triggers of earthquakes in regions once thought stable, such as Utah. Studies reveal that long-dormant faults may reactivate due to natural processes and human activities. In the Pacific Northwest, seismic data show the oceanic plate breaking into fragments, forming microplates and suggesting a slow, stepwise collapse of the subduction zone. This could have implications for earthquake preparedness and hazard estimation throughout the American West.

    Internationally, geologists gathered in Zaragoza, Spain from November fifth to seventh for the fifth International Professional Geology Conference. Attendees discussed pressing challenges, including geological hazards, mineral sustainability, and professional development. This global knowledge exchange highlights the interconnected nature of geoscience, as the United States and other nations respond to evolving resource risks and natural hazards.

  • Revolutionizing Earth's Dynamics: Groundbreaking Geological Findings and Critical Mineral Insights

    Revolutionizing Earth's Dynamics: Groundbreaking Geological Findings and Critical Mineral Insights
    Nov 13 2025
    Recent developments in geology reveal significant findings about Earth's dynamic systems and critical mineral resources. The Hawaiian Volcano Observatory reported that Episode 36 of the ongoing Halemaʻumaʻu eruption at Kīlauea ended on November 9 after approximately five hours of high lava fountains. The south vent produced fountains reaching about 1,200 feet in height while the north vent reached approximately 750 feet. Following the eruption, scientists observed only minor glow from the south vent overnight, with both vents fuming the next morning. Sulfur dioxide emissions remained at background levels between 1,200 and 1,500 tonnes per day. Observatory analysis suggests the next eruptive episode is at least a week away, with more than one week likely before fountaining resumes based on the amount of deflation observed during this episode. The current eruption, which began on December 23, 2024, has been characterized by episodic lava fountaining not observed in any eruptions since the 1983 to 1986 episodic fountains at the beginning of the Puʻuʻōʻō eruption.

    On the national minerals front, the U.S. Geological Survey released an updated critical minerals list on November 6. Uranium has been reinstated to the list after being excluded from the 2022 version, bringing the total number of critical minerals to 60. This reinstatement reflects growing nuclear energy demands in the United States. Meanwhile, researchers have identified a significant issue with American resource management. Scientists discovered that the United States already mines all the critical minerals needed for energy, defense, and technology, yet most are being discarded as mine tailings. Minerals including cobalt, germanium, and rare earth elements are lost in massive amounts during mining operations.

    Additional research published in recent weeks revealed new insights into continental geology. Scientists discovered that continents do not merely split at their surfaces but also peel from below, feeding volcanic activity in oceans. Simulations demonstrate that slow mantle waves strip continental roots and push them deep into oceanic regions, explaining previously mysterious patterns of volcanic activity.

    International geological conferences are convening this month to address these discoveries and other pressing concerns. The 14th World Conference on Earth Science and Geology is taking place November 13 and 14 in Paris, France, bringing together geologists and earth scientists to discuss climate change, environmental science, and advanced technologies for addressing geological hazards. These converging developments underscore how Earth's geological systems continue to reshape our understanding of planetary processes while presenting both challenges and opportunities for resource management and hazard mitigation.

    "Copper Joins Critical Minerals List: Driving U.S. Resource Independence and Geologic Advancements"
    Nov 8 2025
    In the United States this week, the field of geology saw significant developments tied both to natural phenomena and mineral resource policy. The U.S. Geological Survey has added copper to its official 2025 Critical Minerals List, which now totals sixty minerals considered essential to national security and infrastructure. This move, highlighted by American Pacific Mining and reported by the U.S. Geological Survey, is expected to spur new investment and streamline permitting for domestic copper projects. The policy shift directly targets reducing reliance on foreign sources for key metals used in energy, technology, and defense, with copper joining lithium, silver, zinc, and others as priorities for strengthened domestic supply chains. The U.S. government has already launched four new funding initiatives totaling nearly $1 billion and has begun making direct equity investments in large-scale mining projects, such as a five percent stake in the Thacker Pass lithium project in Nevada. Industry experts expect these policy changes to create positive momentum for U.S.-based operations in regions such as Montana and Alaska, where major copper-gold projects could help meet the growing demand for this versatile metal.

    Meanwhile, in Hawaii, the U.S. Geological Survey's Hawaiian Volcano Observatory maintained continuous monitoring of Kilauea Volcano, despite a lapse in federal appropriations. According to the latest daily update, overflows of degassed lava from the north vent persisted during the past twenty-four hours and inflation at the summit continued at a slow rate, suggesting the onset of a new eruptive episode may be imminent between November 8 and 11. These volcanic dynamics underscore the ongoing importance of real-time geological monitoring in hazard preparedness, especially as regional populations and critical infrastructure remain potentially at risk from changes in volcanic behavior.

    On the research front, an international breakthrough came from a team working in Antarctica, where scientists have discovered six-million-year-old ice. As reported by ScienceDaily, this ancient ice represents the oldest direct record yet of Earth's atmosphere and climate, providing invaluable data about the planet’s geologic and environmental history in the deep past. These findings further highlight the role geology plays not only in resource management and hazard mitigation, but also in decoding the climatic narrative of our planet.

    Internationally, the 5th International Professional Geology Conference just concluded in Zaragoza, Spain, focusing on technological advancements and the future of geological practice, while the upcoming 14th World Conference on Earth Science and Geology in Paris will emphasize sustainable resource management and environmental innovation. As these global gatherings and domestic policy shifts illustrate, geology continues to adapt and expand its reach—bridging scientific discovery, resource security, and international collaboration.

  • Yellowstone Seismic Activity Remains Steady, Other US Regions See Expected Geological Shifts

    Yellowstone Seismic Activity Remains Steady, Other US Regions See Expected Geological Shifts
    Nov 5 2025
    Yellowstone National Park has seen increased, but still background, seismic activity over the past month. According to the US Geological Survey, scientists recorded 180 earthquakes in October, with the strongest reaching magnitude three point seven near Mammoth Hot Springs on October twenty eighth. Four earthquake swarms were detected throughout the park, but none suggest heightened volcanic risk. Ground deformation measurements show the end of seasonal uplift, with long-term subsidence of the caldera, a pattern ongoing since twenty fifteen, resuming as winter approaches. Minor eruptions of the Steamboat Geyser remain infrequent, indicating a decline in the geyser’s cycle of heightened activity since twenty eighteen, with only two major eruptions recorded so far this year. Other geysers like Valentine and Guardian continue sporadic eruptions, which is considered normal for the region.

    Nevada experienced a significant earthquake last Saturday, when a magnitude five point three event struck at a shallow depth of about three point seven miles. According to the United States Geological Survey, this is part of a recent surge in seismic activity in the Basin and Range Province. NASA geologists note that this region is characterized by an expanding and thinning crust, causing frequent earthquakes along hundreds of faults over millions of years. Shallow earthquakes like the one in Nevada are generally felt more strongly at the surface. This pattern highlights why the Basin and Range region is considered one of the most seismically active in the United States.

    Moving west, California remains stable on the volcanic front. The California Volcano Observatory reports that monitored volcanoes, including Mount Shasta, Medicine Lake, and Lassen, are all at normal alert levels. Earthquake activity is limited to typical patterns, such as the one hundred and eleven minor earthquakes recorded in the Geysers geothermal area, with the largest registering magnitude three point two.

    In Alaska, the Great Sitkin Volcano continues to erupt lava within its summit crater. The Alaska Volcano Observatory notes low seismicity in recent days, with no major explosions recorded since May twenty twenty-one, although monitoring for renewed unrest continues.

    Hawaii’s Kilauea Volcano remains active. The volcano’s summit is inflating, and sulfur dioxide gas emissions are at background levels. In October, lava fountains during eruption episode thirty-five reached heights of nearly fifteen hundred feet and produced approximately thirteen million cubic yards of lava, covering about two thirds of Halemaʻumaʻu crater’s floor.

    Globally, significant volcanic activity was noted at Ecuador’s Reventador volcano, which is emitting ash plumes, and at several volcanoes in Central America and Indonesia, according to Volcano Discovery. In the United States, however, recent geological events point to ongoing but expected levels of seismic and volcanic activity, with no indications of imminent major eruptions or catastrophic earthquakes at this time.

  • "Yellowstone Seismic Activity, Alaskan Quakes, and Global Geological Insights: The Latest Developments"

    "Yellowstone Seismic Activity, Alaskan Quakes, and Global Geological Insights: The Latest Developments"
    Nov 1 2025
    Geological activity in the United States has continued to present a varied and dynamic picture in the past week. In Yellowstone National Park, the United States Geological Survey reports that volcanic and seismic activity remains at background levels. There were eighty-seven located earthquakes in September, with the largest being a magnitude three point three event fourteen miles south-southwest of Mammoth Hot Springs. Notably, the usually active Steamboat Geyser has had only two major eruptions in twenty twenty-five, indicating a downturn from the period of frequent activity that began in twenty eighteen. Valentine and Guardian Geysers have shown intermittent eruptions, with Valentine erupting for the first time in over twenty years. A new steam vent also opened in the Mud Volcano area, a site familiar with such events. GPS monitoring in the region continues to show seasonal uplift due to snowmelt and groundwater changes, but the area overall maintains its long-term trend of subtle subsidence according to ongoing measurements by EarthScope Consortium and USGS field engineers.

    In Alaska, the Alaska Earthquake Center reports a magnitude two point two earthquake occurring southeast of Girdwood on the night of October thirty-first. The earthquake’s depth was about six miles, and while minor, it reminds researchers of the persistent tectonic activity in Southcentral Alaska driven by the subducting plate boundary that has historically produced much stronger quakes in the region.

    Hawaii remains an active center for volcanology. According to the Hawaiian Volcano Observatory, the Kilauea volcano recently concluded episode thirty-five of its Halemaumau eruption with seven and a half hours of lava fountaining. Both active vents continue to show incandescence and summit inflation is ongoing, with seismic tremor and gas emissions in the normal range. Eruption models suggest another episode is likely in the window between November fourth and eighth, with the largest fountains in the most recent episode reaching heights of up to one thousand five hundred feet. This ongoing volcanic activity produces significant lava flows, which now cover about two thirds of the crater floor.

    Beyond the United States, global geological attention has been focused on marginal seas as highlighted by the recent International Conference on Marine Geology in Guangzhou, China. Experts there discussed the rising impact of sea level changes and coastal management challenges in the face of climate change and rapid urbanization. Meanwhile, October sixth marked International Geodiversity Day worldwide, with events ranging from public walks in Luxembourg’s UNESCO Global Geopark to digital celebrations promoting awareness about the importance of geological variety for environmental resilience. According to recent findings published by ScienceDaily, researchers have also observed a subduction zone actively breaking apart beneath the Pacific Northwest, providing new insight into the forces shaping the continent’s edge and the risk of future major earthquakes. This combination of monitoring, research, and global collaboration underscores the vital role geology plays in helping us understand and adapt to our changing planet.
