  • Earthquakes, Volcanoes, and Climate Change: Geologists Tackle Earth's Transformations

    Earthquakes, Volcanoes, and Climate Change: Geologists Tackle Earth's Transformations
    2025/12/24
    Geologists in the United States have focused closely this week on rapid landscape change driven by both earthquakes and volcanoes, as well as new insights into long term climate and resource risks. In Alaska, the United States Geological Survey reports that a magnitude seven point zero earthquake beneath Hubbard Glacier on December sixth triggered hundreds of landslides and snow avalanches across the Saint Elias Mountains, spanning southeast Alaska and into Canada. Preliminary remote sensing and a Yukon Geological Survey reconnaissance flight show slopes stripped of snow and rock, highlighting how seismic shaking in glaciated terrain can rapidly remodel valley walls and potentially dam streams or alter sediment delivery downstream.

    Farther south in Hawaii, the United States Geological Survey Hawaiian Volcano Observatory continues to track the ongoing summit eruption of Kilauea. A new map released December twenty second shows that lava within Halemaumau crater now averages about sixty eight meters thick, with maximum thickness exceeding one hundred sixty meters, filling nearly four hundred hectares of the summit basin. A monitoring overflight on December second captured spattering lava deep in the north vent and bright yellow native sulfur deposits produced by degassing sulfur dioxide and hydrogen sulfide. These measurements document how quickly magma is rebuilding the summit floor that collapsed in twenty eighteen, offering a real time laboratory for understanding caldera infilling and gas driven mineral formation.

    On the continental United States mainland, concern is rising over the stability of land and water resources. A recent Geological Society of America news release highlights that parts of the Willcox Basin in southern Arizona are sinking rapidly due to groundwater withdrawal, with subsidence threatening infrastructure and altering drainage. At the same time, another GSA release warns that drainage from abandoned coal mines could represent a significant and under counted source of carbon emissions, linking classic economic geology with climate change science.

    Looking at Earths future, ScienceDaily reports new research identifying a missing feedback in the global carbon cycle that could cause warming driven by fossil fuel emissions to overshoot and, paradoxically, help push the planet toward a future ice age on geologic time scales. In Washington, the Interior Department and the United States Geological Survey have issued an expanded twenty twenty five critical minerals list, now including sixty minerals such as copper, uranium, metallurgical coal, and phosphate, underscoring how geologic supply, national security, and clean energy transitions are tightly intertwined. Worldwide, major conferences from the American Geophysical Union meeting in New Orleans to international geology and geophysics gatherings in Europe, Asia, and Africa are weaving these themes together, emphasizing that from sudden earthquakes to slow subsidence, geology remains central to understanding and managing a changing planet.

  • Boosting Domestic Minerals, Monitoring Volcanic Risks, and Coastal Resilience: Evolving U.S. Geological Priorities

    Boosting Domestic Minerals, Monitoring Volcanic Risks, and Coastal Resilience: Evolving U.S. Geological Priorities
    2025/12/17
    The United States Geological Survey issued its final 2025 List of Critical Minerals on November seventh, expanding the roster to sixty key materials essential for national security, supply chains, and industry. According to the USGS announcement, this update responds to the Energy Act of 2020 and incorporates executive orders on unleashing American energy and reinvigorating clean coal, adding uranium, metallurgical coal, potash, silicon, copper, silver, rhenium, lead, and retaining boron, arsenic, tellurium, and phosphate after interagency reviews from Defense, Energy, Agriculture, and others. The methodology, detailed in USGS Open-File Report 2025-1047, analyzed over twelve hundred disruption scenarios across eighty-four commodities and four hundred two industries, prioritizing economic impacts from foreign trade risks and single-point domestic failures. Interior Secretary emphasized the list's dynamic nature, with biennial updates planned based on supply shifts, demand, and policy.

    In Hawaii, Kilauea volcano's summit eruption paused as of December seventeenth, per the USGS Hawaiian Volcano Observatory notice. Intermittent glow persists in the south vent of Halemaumau crater, with tremor spikes, following spattering lava observed deep in the north vent on December second during an overflight. Yellow sulfur deposits surround the vents, formed when sulfur dioxide and hydrogen sulfide gases react and cool at the surface, as captured in USGS video by geologist K. Mulliken. Eruption activity continued through December sixteenth, highlighting ongoing monitoring in the islands.

    A UMass Amherst and Massachusetts Geological Survey study released December sixteenth reveals ocean sediments are vital for northeastern United States salt marshes to survive sea-level rise. Researchers describe it as a wake-up call on oceans' role in delivering sediments that help marshes keep pace with rising waters along coasts from Maine to Virginia.

    At the American Geophysical Union Annual Meeting in New Orleans this week, volcanologist Pavel Izbekov from the Alaska Volcano Observatory presented research on crystal clusters in magma from Bogoslof volcano's 2016-2017 eruptions. Diffusion chronometry in clinopyroxene, plagioclase, and amphibole crystals dated a critical decompression event to early March 2017, matching seismic and sulfur dioxide spikes, offering a new tool to forecast eruptions by reading magma history in mineral zones.

    These developments underscore emerging patterns: bolstered domestic mineral strategies amid global risks, persistent volcanic hazards in the Pacific, coastal resilience tied to ocean dynamics, and advancing crystal-based eruption predictions, all shaping United States geology priorities.

  • 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.
