  • Volcanic Unrest and Major Earthquake Shake Up US Geologic Landscape

    Volcanic Unrest and Major Earthquake Shake Up US Geologic Landscape
    2025/12/13
    In the past week, geological activity in the United States has centered on volcanic unrest and a major earthquake, highlighting ongoing hazards in volcanic hotspots and tectonically active regions. Kilauea volcano on Hawaii's Big Island continues its summit eruption, which began last December and remains active. U.S. Geological Survey reports from December 13 indicate the eruption paused after episode 38, with models forecasting episode 39 between December 22 and 27. Precursory lava overflows could start anytime from vents in Halemaumau crater, where inflation rates and gas pistoning signal building pressure. On December 2, observatory overflights captured spattering lava deep in the north vent, surrounded by yellow native sulfur deposits formed from reacting volcanic gases. The volcano alert level stays at watch, with east rift zone emissions low.

    Across the Pacific in Alaska, Great Sitkin volcano on the Aleutian Islands maintains its continuing eruption, as detailed in Volcano Discovery's December 12 update. Low-level explosive and effusive activity persists, producing ash plumes and lava flows, consistent with patterns at this remote hotspot volcano since 2021.

    Yellowstone Volcano Observatory's December update contrasts these events with the Yellowstone Caldera system's normal background activity. November saw 251 earthquakes, the largest magnitude 3.2, amid slight subsidence and diminished Steamboat Geyser activity. Both Kilauea and Yellowstone stem from fixed hotspots driving magma plumes, but oceanic crust in Hawaii allows fluid basaltic eruptions, while thick continental crust at Yellowstone favors explosive rhyolitic events.

    A significant seismic event struck on December 6, when a magnitude 7.0 oblique-slip earthquake hit 6 miles below Hubbard Glacier in Alaska's St. Elias Mountains, 55 miles north of Yakutat. U.S. Geological Survey notes it triggered landslides and snow avalanches, underscoring risks in glaciated terrains prone to rapid mass wasting.

    Emerging patterns reveal steady unrest at U.S. hotspots, with Kilauea episodes accelerating and Alaska facing compounded volcanic-seismic threats. Globally, 44 volcanoes show continuing eruptions per the Smithsonian USGS Weekly Volcanic Activity Report ending December 9, but U.S. sites dominate recent domestic headlines, emphasizing vigilant monitoring amid climate-influenced glacier dynamics and mineral resource shifts like the USGS expanded 2025 critical minerals list including uranium and metallurgical coal.

  • 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
    2025/12/06
    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
    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.
