  • Kilauea Volcano Builds Towards Explosive Eruption in Hawaii

    Kilauea Volcano Builds Towards Explosive Eruption in Hawaii
    Jan 24 2026
    The United States Geological Survey reports growing pressure at Kilauea volcano in Hawaii Volcanoes National Park on Hawaii's Big Island. Lava emerged from summit vents on Thursday night, January 22, 2026, as the volcano builds toward its next eruptive episode, potentially episode 41 of the year-long summit eruption. Scientists forecast this could begin between January 23 and 25, based on current inflationary tilt models showing a saw-tooth pattern of ground deformation. Each episode requires more pressurization, indicated by a black arrow on deformation graphs from the Hawaiian Volcano Observatory.

    Elevated microseismicity persists, with earthquakes spread widely beneath the summit region, linked to migrating magmatic pressure. The observatory's information statement on January 23 details three possible outcomes. First, the eruption could continue from north and south vents in Halemaumau crater for an unforeseeable time, possibly shifting to continuous lava flow as vents break down. Second, a new vent might form in the summit region or upper southwest rift zone, signaled by tightly clustered earthquakes and shallow crack deformation, similar to episode 30 on August 6, 2025, when a fissure opened in Halemaumau's southwest wall. Third, and least likely, magma could migrate into the east rift zone, causing intrusion or eruption, with earthquakes moving southeast and summit deflation.

    No changes in ground deformation suggest magma entering new areas yet, but inflation continues between earthquake swarms. The volcano alert level remains at watch, with close monitoring. Big Island Video News highlights this as part of ongoing summit activity, with all images courtesy of the USGS.

    Elsewhere in the US, the USGS released an assessment of undiscovered resources in the Woodford and Barnett shales of the Permian Basin, spanning New Mexico and Texas. It estimates 28.3 trillion cubic feet of gas, enough for 10 months of national supply, and 1.6 billion barrels of oil, or 10 weeks' worth.

    These events underscore patterns of volcanic inflation and resource potential in tectonically active US regions. Kilauea's episodic fountaining reveals magma reservoir dynamics, while Permian assessments highlight untapped shale plays amid energy demands. No major nationwide seismic shifts reported this week, but vigilance continues at key sites.

  • Reshaping Earthquake Hazards and Water Resources: Groundbreaking Geologic Discoveries Across the U.S.

    Reshaping Earthquake Hazards and Water Resources: Groundbreaking Geologic Discoveries Across the U.S.
    Jan 21 2026
    Recent geological discoveries across the United States are revealing complex subsurface structures and ongoing seismic activity that scientists say could reshape our understanding of earthquake hazards and water resources.

    In New Mexico and Texas, the U.S. Geological Survey announced low-level helicopter flights beginning mid-January over four counties surrounding Clovis and Cannon Air Force Base. According to the USGS, these surveys are imaging geology and aquifers across approximately 1,300 square miles using airborne geophysical technology. The aircraft, equipped with a towed hoop deployed about 100 feet beneath the helicopter, measures variations in Earth's electrical properties and magnetic fields created by different rock types. Burke Minsley, a USGS research geophysicist overseeing the project, noted that this airborne survey allows scientists to cover large areas very effectively. The resulting three-dimensional models will map aquifer thickness saturated with groundwater to depths up to about 1,000 feet below the surface, supporting critical groundwater studies in cooperation with the U.S. Air Force.

    In Northern California, University of California Davis researchers have uncovered a surprisingly complex earthquake zone at the Mendocino Triple Junction where three major tectonic plates converge. The study, published on January 17, 2026, reveals that the region involves five moving pieces rather than just three major plates, with two hidden deep below the surface. Scientists discovered that a portion of the North American plate has broken away and is being dragged downward along with the Gorda plate as it sinks beneath North America. Additionally, the Pacific plate is pulling a mass of rock called the Pioneer fragment beneath the North American plate as it moves northward. This fragment, which was once part of the ancient Farallon plate, lies along a nearly flat fault that cannot be seen at the surface.

    Meanwhile, Utah geologists have created new high-resolution maps of active faults in regions beyond the Wasatch Front, using advanced elevation data to identify faults that have ruptured Earth's surface within the past 2.6 million years. The Utah Geological Survey reports these maps reveal earthquake risk in rapidly growing rural regions previously less studied.

    At Yellowstone, the U.S. Geological Survey confirmed that an area on the north rim of the caldera began uplifting slightly in July 2025, mirroring deformation that occurred during 1996 through 2004. These recent geological activities underscore how continuously Earth reshapes itself, with implications for water security, infrastructure safety, and volcanic monitoring across the nation.

  • Groundwater Mapping Reveals Vast Untapped Resources Across US, as Global Seismic and Volcanic Activity Intensifies

    Groundwater Mapping Reveals Vast Untapped Resources Across US, as Global Seismic and Volcanic Activity Intensifies
    Jan 17 2026
    Recent geological activity across the United States and worldwide reveals significant developments in earthquake and volcanic monitoring, as well as groundwater research that could reshape water management strategies.

    Researchers at Princeton University and the University of Arizona have completed an unprecedented mapping of United States groundwater resources. Using artificial intelligence combined with over one million direct measurements, they have created a detailed model revealing that the continental United States contains approximately 306,000 cubic kilometers of fresh water underground, more than thirteen times the volume of all the Great Lakes combined. This research, published in Communications Earth and Environment on January 14, divides the continental United States into a grid of more than eight billion squares, each measuring thirty meters on each side, to estimate groundwater depth and volume with unprecedented precision. The findings identify previously unknown supplies of shallow groundwater that could significantly impact irrigation and water infrastructure decisions, particularly in agricultural regions dependent on center-pivot irrigation systems.

    Globally, seismic activity has intensified in recent days. According to the World Earthquake Report for January 17, 2026, the planet experienced moderate seismic activity, with seven earthquakes of magnitude five point zero or greater, thirty-seven earthquakes between magnitude four point zero and four point nine, one hundred thirty-two earthquakes between magnitude three point zero and three point nine, and three hundred twenty-seven earthquakes between magnitude two point zero and two point nine, totaling five hundred three recorded earthquakes.

    In California, a magnitude three point five earthquake struck near Middletown on January 10 at approximately six fifty-nine PM Universal Time, located eighteen kilometers northwest of the town at a depth of three point five kilometers.

    Volcanic activity continues as a major area of concern worldwide. The Volcanic Activity Worldwide report from January 17 documents ongoing explosive activity at Sakurajima in Kyushu, Japan, with the Volcanic Ash Advisory Center Tokyo issuing warnings about volcanic ash dispersal. Additionally, volcanic monitoring between January 8 and 14 recorded significant activity at multiple locations, with seismic stations documenting daily rockfall events and pyroclastic density currents.

    The United States Geological Survey is actively soliciting project proposals for Fiscal Year 2026 grants focused on earthquake hazards science, indicating ongoing efforts to improve understanding and monitoring of seismic risks. Meanwhile, the Hawaiian Volcano Observatory continues its seventeenth annual Volcano Awareness Month on the Island of Hawaii throughout January, promoting public understanding of volcanic hazards and geological processes in one of the world's most geologically active regions.

  • Dynamically Evolving Geological Landscape Across America: Volcanic Activity, Deformation, and Hydrogen Exploration Surge

    Dynamically Evolving Geological Landscape Across America: Volcanic Activity, Deformation, and Hydrogen Exploration Surge
    Jan 14 2026
    Recent geological developments across the United States reveal a dynamic landscape of volcanic activity, ground deformation, and evolving energy exploration. The Hawaiian Volcano Observatory reported that Kīlauea on the Island of Hawaii experienced its fortieth fountaining episode on January 12, 2026, with lava fountains reaching heights of approximately 800 feet. This represents the ongoing eruptive activity within Halema'uma'u crater that has captured scientific attention throughout the region.

    In the Yellowstone caldera system, the U.S. Geological Survey's Yellowstone Volcano Observatory documented the return of an important deformation pattern. Beginning in July 2025, an area along the north rim of the Yellowstone caldera, situated south of Norris Geyser Basin, began experiencing uplift. This phenomenon mirrors similar deformation that occurred in the same location between 1996 and 2004, suggesting cyclical subsurface processes that warrant ongoing monitoring.

    Meanwhile, Utah is gaining prominence in earthquake risk assessment. The Utah Geological Survey has released new high-resolution elevation data that has enabled mapping of active faults across more regions of the state beyond the traditionally focused Wasatch Front and northern areas. These maps reveal earthquake risk in rapidly growing rural regions, classifying faults that have ruptured the earth's surface within the past 2.6 million years as active fault lines.

    A particularly significant development involves the emerging field of geologic hydrogen exploration. According to reporting from the drilling and hydrogen sector, Iowa and Minnesota have recently clarified the legal definitions of geologic hydrogen, addressing regulatory uncertainties that have previously complicated development. Wyoming has taken a different approach, relying on existing gas statutes to accommodate hydrogen exploration without explicit new legislation. The U.S. Geological Survey recently released the first continental-scale map of geologic hydrogen potential across the contiguous United States, marking a research milestone. Companies such as Koloma are actively advancing exploration efforts with substantial funding, focusing on geological assessment, data collection, and test well planning to confirm whether viable hydrogen resources exist and understand their subsurface behavior.

    Additionally, the U.S. Geological Survey announced low-level aerial surveys scheduled over parts of New Mexico and Texas to image geology and aquifers, demonstrating continued commitment to understanding subsurface water resources and geological characteristics across the southwestern United States.

    These developments collectively illustrate an evolving geological landscape where volcanic monitoring, earthquake hazard assessment, groundwater evaluation, and novel resource exploration are all advancing simultaneously across American territories and states.

  • Unlocking Earth's Secrets: New Geologic Insights Across the U.S. Uncover Earthquake and Landslide Risks

    Unlocking Earth's Secrets: New Geologic Insights Across the U.S. Uncover Earthquake and Landslide Risks
    Jan 10 2026
    Across the United States, geologists are opening the new year with fresh insight into how the ground beneath us behaves, and what that means for people living on it. The Utah Geological Survey reports that new high resolution light detection and ranging mapping has revealed a far more complex network of active faults in central Utah than previously recognized, including in rapidly growing counties such as Sanpete, Sevier, and Millard, sharpening estimates of where strong earthquakes could strike next. According to the Survey, using light detection and ranging allows geologists to see through vegetation and pick out subtle fault scarps formed by past large earthquakes, improving hazard maps that guide building codes and infrastructure planning.

    Farther east, a January issue of GSA Today from the Geological Society of America details how geologists mapped thousands of landslides triggered by Hurricane Helene in the southern Appalachian Mountains, producing an emergency landslide hazard map while the disaster was still unfolding. That work is now being used to refine long term assessments of slope stability and to identify communities at highest risk in future extreme rainfall events.

    In Yellowstone National Park, the United States Geological Survey highlights the top geologic developments of the past year in its January Yellowstone update, noting that the park experienced more than one thousand earthquakes in twenty twenty five, on the low end of average, but with notable ground deformation that scientists will watch closely in twenty twenty six, along with continued but declining activity at Steamboat Geyser and new hydrothermal features that testify to the restless magma system below.

    On the volcanic front in Hawaii, the Hawaiian Volcano Observatory reflects on thirty eight episodes of lava fountaining at Kilauea summit over the past year and uses Volcano Awareness Month events to underscore how quickly hazards can change on an active shield volcano and how essential public preparedness remains.

    Beyond the United States, global monitoring by Volcano Discovery shows that in just one recent day, January ninth, twenty twenty six, the largest earthquakes reached magnitude five point six in the Coral Sea near Vanuatu, with additional magnitude five events in New Zealand and along the Pacific Rim, illustrating that most significant seismic energy release continues to concentrate along plate boundaries, while interior regions like much of the United States rely on detailed mapping and geologic sleuthing to understand quieter but still dangerous faults.

  • Yellowstone Volcano Remains Stable, Utah Faults Revealed, and Induced Seismicity Trends Highlighted in Geologic Roundup

    Yellowstone Volcano Remains Stable, Utah Faults Revealed, and Induced Seismicity Trends Highlighted in Geologic Roundup
    Jan 7 2026
    In early January 2026, the United States Geological Survey released its Yellowstone Volcano Observatory monthly update, highlighting ongoing geological activity in Yellowstone National Park, Wyoming. Yellowstone Caldera remains at normal alert levels, with 79 located earthquakes in December 2025, the largest measuring magnitude 2.7. Subtle uplift of two to three centimeters along the north caldera rim, south of Norris Geyser Basin, began in July 2025 and continues, resembling patterns from 1996 to 2004, according to continuous GPS and satellite radar measurements by the USGS. Within the caldera, long-term subsidence since 2015 paused, with up to two centimeters of uplift since May 2025, possibly signaling a shift from subsidence or an extended seasonal effect.

    Hydrothermal features dominated 2025's top stories, per the USGS Yellowstone monthly update for January 2026. Black Diamond Pool in Biscuit Basin saw at least three small eruptions on December 8, 18, and 20, 2025, captured by new camera and infrasound monitoring following a 2024 explosion. Steamboat Geyser in Norris Geyser Basin, the world's tallest active geyser, erupted for the third time in 2025 on December 31 just after 10 p.m. Mountain Standard Time, marking a decline from prior active phases.

    Elsewhere in the US, the Utah Geological Survey announced on January 5, 2026, new high-resolution maps revealing active faults in central Utah's rural areas. These faults, which have ruptured the surface within the past 2.6 million years, highlight growing earthquake risks amid rapid development beyond the Wasatch Front.

    A USGS report notes human-induced earthquakes from oil and gas operations have reshaped seismic patterns nationwide, increasing tremors in regions like Oklahoma and Texas. High Country News's January 2026 issue explores deep geologic time in the West, linking ancient events like the Arizona Meteor Crater asteroid impact to Grand Canyon formation and plate tectonics insights from scientist Tanya Atwater on the San Andreas Fault in California.

    These developments underscore Yellowstone's dynamic hydrothermal and seismic baseline, emerging fault clarity in Utah, and induced seismicity trends, with no signs of escalation beyond normal variability. Globally, a massive hydrothermal field off Greece stunned scientists in late December 2025, but US patterns emphasize steady monitoring amid human influences.

  • Yellowstone Dominates USGS Top Geological Stories of 2025: Seismic Activity, Geyser Eruptions, and Hydrothermal Wonders Revealed

    Yellowstone Dominates USGS Top Geological Stories of 2025: Seismic Activity, Geyser Eruptions, and Hydrothermal Wonders Revealed
    Jan 3 2026
    The United States Geological Survey released its top five geological stories from 2025 this week, providing a comprehensive overview of dynamic activity across American volcanic regions. Yellowstone National Park dominated the report with several significant developments. The park experienced 1,136 earthquakes throughout 2025, keeping seismic activity at background levels. Most notably, ground deformation began occurring in July in an area south of Norris Geyser Basin along the north caldera rim, where satellite radar and GPS data detected uplift of two to three centimeters. Scientists note this deformation pattern persisted through the end of the year and may represent a transition to a new form of deformation in the region, similar to patterns observed from 1996 to 2004.

    Steamboat Geyser, the world's tallest geyser located in Norris Geyser Basin, erupted only three times during 2025, with the final eruption occurring on December 31st just after ten PM Mountain Standard Time. This continues a declining trend from its peak activity between 2018 and 2020, when it erupted 48 times per year. Scientists expect this phase of activity to continue declining throughout 2026 as the geyser gradually returns to dormancy.

    The report also highlighted significant hydrothermal activity across Yellowstone, with several new thermal features emerging throughout the year. In Biscuit Basin, where a hydrothermal explosion occurred in July 2024, new monitoring equipment captured multiple eruptions at Black Diamond Pool. At least three small eruptions were recorded in December alone on the eighth, eighteenth, and twentieth, detected through both camera monitoring and acoustic sensing technology. The USGS emphasized that Black Diamond Pool remains highly active despite its explosive history.

    A notable rumor dispelled by the USGS concerned claims that animals were fleeing Yellowstone National Park. Scientists found no credible evidence supporting such migration patterns. The report stressed that Yellowstone remains a geologically dynamic region where features regularly turn on and off, creating natural variations that sometimes fuel unfounded speculation.

    In Hawaii, the Hawaiian Volcano Observatory reported that 2025 was a historic year for volcanic activity on the Island of Hawaii. Thirty-eight episodes of lava fountaining occurred at Kīlauea's summit, underscoring the active volcanic landscape residents and visitors navigate throughout the islands. These developments highlight how American volcanic regions continue providing scientists with opportunities to monitor and understand critical geological processes shaping our landscape.

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

    Earthquakes, Volcanoes, and Climate Change: Geologists Tackle Earth's Transformations
    Dec 24 2025
    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.
