  • North American Craton Actively Thinning as Rock Blobs Drip From Ancient Foundation

    North American Craton Actively Thinning as Rock Blobs Drip From Ancient Foundation
    2026/02/25
    Geoscientists at the University of Texas Jackson School of Geosciences have discovered that the underside of the North American continent is actively dripping away in blobs of rock from its ancient craton foundation. Lead researcher Junlin Hua, now at the University of Science and Technology of China, used advanced full-waveform seismic tomography from the EarthScope project to reveal these drips beneath the craton, which spans most of the United States and Canada. The process, driven by the Farallon tectonic plate subducting 600 kilometers away, is causing widespread thinning across the craton, not just in one spot, as computer models confirm dripping halts when the plate is removed. This ongoing thinning challenges the craton's famed stability after billions of years and offers a live view of deep Earth dynamics.

    In Hawaii, Kilauea volcano's summit at Halemaumaumau paused after episode 42 of lava fountaining on February 15, which lasted under ten hours with peaks of 400 meters from south and north vents, erupting 11.4 million cubic meters of lava and scattering light ash downwind. United States Geological Survey reports show inflation resuming, with 17.2 microradians of tilt recovery and sulfur dioxide emissions at 1000 to 1500 tonnes daily, signaling episode 43 may soon begin amid low rift zone activity. A minor magnitude 1.8 earthquake struck six miles south of Skwentna, Alaska, on February 25 at a depth of 72 kilometers, per the Alaska Earthquake Center.

    Elsewhere in the United States, unrest at Ahyi volcano in the Northern Mariana Islands eased by February 24, according to United States Geological Survey Northern Mariana Islands monitoring. Stanford University researchers mapped rare deep mantle earthquakes globally on February 20, clustering near the Bering Strait in North America and beneath the Himalayas, using seismic wave analysis to probe the crust-mantle boundary and tectonic drivers up to 80 kilometers deep.

    These events highlight emerging patterns of mantle instability under North America, from cratonic drips to subtle quakes, alongside Hawaii's persistent volcanism, underscoring active geological flux shaping the continent today.

  • Yellowstone Shows Breathing Pattern as Kilauea Erupts: February 2026 Volcano Updates

    Yellowstone Shows Breathing Pattern as Kilauea Erupts: February 2026 Volcano Updates
    2026/02/21
    In early February 2026, the Yellowstone Volcano Observatory reported normal background activity at Yellowstone National Park in Wyoming. Continuous global positioning system stations detected subtle ground deformation, with uplift along the north caldera rim and subsidence within the caldera itself, resembling a breathing pattern after years of alternating rise and fall. The University of Utah Seismograph Stations recorded 100 earthquakes in January, and two confirmed eruptions occurred at Black Diamond Pool in Biscuit Basin. According to the Yellowstone Volcano Observatory, these measurements highlight ongoing monitoring of millimeter-scale movements using precise instruments.

    Meanwhile, at Kilauea volcano on Hawaii's Big Island, episode 42 of summit eruptions in Halemaumau crater unfolded on February 15. Lava fountaining from north and south vents lasted under ten hours, peaking at 400 meters or 1300 feet high from the south vent. The United States Geological Survey estimated 15 million cubic yards of lava erupted, producing light tephra including fine ash and Pele's hair that drifted downwind to nearby communities. By February 21, the eruption paused, with weak glow fading, robust degassing plumes carrying southwest, and inflationary tilt recovering nearly 11.6 microradians on the UWD tiltmeter. Sulfur dioxide emissions likely hit 100,000 tonnes per day during fountaining, dropping to 1000 to 5000 tonnes per day in the pause, per USGS Hawaiian Volcano Observatory updates.

    Elsewhere in the United States, geologic hydrogen exploration advanced with first regulatory steps in various states. Companies like Koloma conducted geological assessments and test well planning, supported by the United States Geological Survey's new continental-scale map of hydrogen potential across the contiguous states. This marks early progress in identifying underground resources, though widespread drilling remains exploratory.

    A University of Utah Geology and Geophysics presentation on February 3 detailed karst processes in Colorado's Pikes Peak region, including Iron Spring in Pikes Peak Granite and sites in Williams Canyon and migmatite formations. Monitoring revealed water mixing creating surface voids, challenging karst topography mapping, with no clear seasonality in off-gassing from wells at varying depths.

    Katmai Volcano in Alaska maintained background activity as of February 20, according to the United States Geological Survey Alaska Volcano Observatory. These events underscore patterns of episodic volcanism in the west, subtle deformations signaling magma dynamics, and emerging energy resource pursuits amid steady monitoring.

  • Yellowstone Volcano Holds Steady, Madison Copper-Gold Discoveries Shine, Kilauea Eruption Pauses: US Geology Insights Unveiled

    Yellowstone Volcano Holds Steady, Madison Copper-Gold Discoveries Shine, Kilauea Eruption Pauses: US Geology Insights Unveiled
    2026/02/18
    In early February 2026, the Yellowstone Volcano Observatory reported steady activity at Yellowstone National Park in Wyoming. During January, the University of Utah Seismograph Stations recorded 100 earthquakes, while deformation measurements showed subtle uplift along the north caldera rim and subsidence within the caldera itself. Two confirmed eruptions occurred at Black Diamond Pool in Biscuit Basin, yet the volcano remains at normal background levels. Ground deformation continues a pattern resembling breathing, with prior years alternating between uplift and subsidence, as detailed in the observatory's monthly update.

    Meanwhile, in Montana, American Pacific Mining announced significant geological discoveries at its Madison Copper-Gold Project on February 6. Lower underground water levels exposed 150 feet of previously inaccessible ramp, revealing highly altered rock ideal for detailed sampling and mapping. Geologists also identified a phreatic breccia in the east rib, about 700 feet from the portal, featuring intrusive clasts with chalcocite veins and native copper. This breccia links underground workings to the surface Victoria Pit, marking the sixth distinct breccia type at the site and highlighting the vigor of the hydrothermal system. These findings refine vectors toward potential porphyry and carbonate replacement deposits, sharpening drill targets ahead of the planned program this quarter.

    On Hawaii's Big Island, Kilauea volcano experienced episode 42 of its summit eruption in Halemaumau crater. Lava fountaining from north and south vents lasted under 10 hours on February 15, peaking at 400 meters from the south vent and erupting 15 million cubic yards of lava. Light tephra, including fine ash and Pele's hair, fell in downwind communities. By February 18, the eruption paused, per USGS Hawaiian Volcano Observatory updates.

    These events underscore emerging patterns in United States geology: cyclic deformation and hydrothermal activity at Yellowstone signal ongoing caldera dynamics without elevated risk, while Madison's breccias reveal complex mineralization systems boosting copper-gold exploration. Kilauea's episodic fountaining reflects persistent magma supply beneath the island. Such observations, drawn from targeted fieldwork and monitoring, enhance predictive models for volcanic and mineral resources across the nation.
