  • 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.
    2026/01/21
    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
    2026/01/17
    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
    2026/01/14
    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.
