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

    Heightened Volcanic Activity and Shifting Subsurface Dynamics Across the United States
    2025/11/29
    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"
    2025/11/26
    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.

  • Volcanic Rumblings, Resource Discoveries, and Glacial Melt: Geology News Highlights Across the United States

    Volcanic Rumblings, Resource Discoveries, and Glacial Melt: Geology News Highlights Across the United States
    2025/11/24
    Geology news this week in the United States has been dominated by new volcanic activity, advances in natural resource assessments, and ongoing research on Earth’s dynamic systems. The United States Geological Survey reported that the Kilauea volcano in Hawaii remains active. On November seventeenth, Observatory staff conducted fieldwork inside the closed area of Hawaii Volcanoes National Park. They observed fresh evidence of hazards left by the recent episode of vigorous lava fountaining. This activity underlines Kilauea’s status as one of the world’s most closely monitored volcanoes. According to VolcanoDiscovery and the USGS, the eruption continues with intermittent explosive and effusive activity, maintaining elevated risk levels for the region’s inhabitants and park infrastructure.

    Elsewhere, the Smithsonian Global Volcanism Program noted that both Kilauea in Hawaii and Great Sitkin in the Aleutian Islands remain in a continuing eruptive state. The Smithsonian points out that globally, forty-four volcanoes are currently classified as in eruption, with approximately twenty showing daily activity at any time. Worldwide, major volcanic events include continuing eruptions at Italy’s Mount Etna, Indonesia’s Semeru and Ibu volcanoes, and Guatemala’s Fuego. These highlight geothermal instability not only in the United States but across volcanic belts worldwide, reflecting persistent geological hazards and research opportunities.

    Beyond volcanoes, resource geology made headlines as the United States Geological Survey announced significant progress in mineral and energy resource assessments. On November twentieth, the USGS revealed new estimates for the Niobrara formation, stretching across southwestern Wyoming and northwestern Colorado. This assessment indicates approximately seven hundred three million barrels of oil and nearly six trillion cubic feet of gas may be undiscovered in this unit. A similar report for the Phosphoria system, also spanning Wyoming and Colorado, details an estimated three million barrels of oil and over six hundred billion cubic feet of gas. These studies reflect the current government and scientific focus on boosting domestic energy and mineral supplies, particularly from older and inactive mine sites.

    Meanwhile, the ongoing melting of glaciers continues to concern geologists worldwide. ScienceDaily describes new findings on how hidden underwater waves, driven by iceberg calving in Greenland, are accelerating glacial melt at an unprecedented rate. Satellite studies further reveal that the Hektoria Glacier in Antarctica underwent the fastest recorded modern ice retreat, demonstrating the rapid sensitivity of ice sheets to oceanic and atmospheric changes.

    November also marked the tenth anniversary of the UNESCO Global Geoparks initiative. As highlighted by the Global Geoparks Network, these parks continue to play a crucial role in conserving the planet’s geological heritage and supporting research, education, and sustainable tourism, both in the United States and globally. The recent developments underscore geology’s vital role in hazard monitoring, resource management, and environmental stewardship, with American scientists and agencies at the forefront of these efforts.
