  • Kilauea Erupts Again as US Geology Reveals Advances in Hydrogen, Landsat, and Paleontology

    Kilauea Erupts Again as US Geology Reveals Advances in Hydrogen, Landsat, and Paleontology
    2026/01/31
    The United States Geological Survey Hawaiian Volcano Observatory reports that Kilauea volcano in Hawaii remains highly active, with episode 41 of the ongoing Halemaumau eruption occurring on January 24, 2026. This episode began around 11:10 a.m. Hawaii Standard Time, triggered by a sharp increase in volcanic tremor and deflationary tilt recorded at the Ue Kahuna tiltmeter. North and south vents produced lava fountains peaking at 460 to 480 meters, or 1500 to 1575 feet, just after 12:30 p.m., with the highest instantaneous effusion rate reaching 1050 cubic yards per second. The eruption lasted eight hours and 18 minutes, ending at 7:29 p.m., and released an estimated 14 million cubic yards of lava, covering 80 to 85 percent of the Halemaumau crater floor. The Ue Kahuna tiltmeter measured 31 microradians of deflation during the event.

    Following the episode, rapid rebound of inflationary tilt, glow from the vents, and low-level tremor suggest another lava fountaining episode is likely soon. Seismicity and ground deformation in the East Rift Zone and Southwest Rift Zone stay very low, while sulfur dioxide emissions from the East Rift Zone remain below detection limits. Hazards persist around Kilauea caldera, including unstable crater walls, ground cracking, rockfalls, and earthquake-enhanced instability, keeping the caldera rim closed to the public since late 2007.

    Elsewhere in the United States, the United States Geological Survey released its first continental-scale map of geologic hydrogen potential across the contiguous states, aiding early exploration efforts. States like Iowa and Minnesota are clarifying regulatory definitions for naturally occurring hydrogen, while companies such as Koloma advance geological assessments and test well planning. The Latest in Landsat newsletter from the United States Geological Survey highlights 2025 milestones, including a growing data archive exceeding 200,000 terabytes and a new Landsat Science Team to support future missions.

    A Geological Society of America news release on January 21, 2026, details research in the journal Geology showing extremely rapid evolution of new species after the end-Cretaceous mass extinction, based on fossil evidence from North American sites. These developments underscore emerging patterns in United States geology, from persistent volcanic unrest in Hawaii to advancing energy resource mapping and paleontological insights into recovery from ancient catastrophes. Worldwide, volcanic activity continues at sites like Santiaguito in Guatemala and Merapi in Indonesia, but United States events dominate recent monitoring.

  • Groundbreaking US Geology Discoveries Uncover Hidden Faults, Shifting Plates, and Ancient Connections

    Groundbreaking US Geology Discoveries Uncover Hidden Faults, Shifting Plates, and Ancient Connections
    2026/01/28
    In the past week, United States geology news highlights groundbreaking discoveries in tectonics, satellite monitoring, water trends, and ancient connections. Researchers at the University of Colorado Boulder and University of California Davis analyzed small low-frequency earthquakes in the Pacific Northwest, revealing hidden faults at the Mendocino Triple Junction off northern California. According to Science magazine, this hotspot where the North American, Gorda, and Pacific plates converge actually involves five moving pieces, not three. A chunk of the North American plate has broken off and is sinking with the Gorda plate, while the Pioneer fragment of older rock drags underneath. This shifts the plate boundary shallower than models predicted, explaining the 1992 magnitude 7.2 earthquake's unusual depth. Geophysicist Amanda Thomas notes that without understanding these processes, seismic hazard prediction remains challenging, especially near the San Andreas fault and Cascadia subduction zone.

    The United States Geological Survey announced a new Landsat Science Team to advance satellite data for Earth surface changes. The USGS January 2026 Landsat newsletter reports that 2025 milestones included the data archive surpassing 200,000 terabytes and celebrations of Landsat 7's legacy, aiding industries in tracking geology worldwide through this NASA-USGS partnership.

    USGS Water News from January 9 details thermoelectric power plants as top water users, with trends showing shifts, alongside a national nutrient study indicating progress against pollution despite population growth. The FireALT dataset baselines permafrost thaw post-wildfire in North America, revealing deeper thaw in the first two decades followed by recovery, threatening Arctic infrastructure as warming accelerates.

    High Country News on January 23 links Arizona's Meteor Crater to the Grand Canyon, where driftwood high in caves suggests the ancient impact damming the river, uncovering deep time legacies in the West. Wyoming's 3.5 billion-year-old rocks remind us of Earth's constant change.

    Worldwide, a G4 severe geomagnetic storm hit January 19 from a coronal mass ejection, per NOAA's Space Weather Prediction Center, while VolcanoDiscovery logged January's largest quake at magnitude 6.5 off Mexico. These events underscore emerging patterns of complex tectonics, climate-driven permafrost shifts, and vast data tools refining US geologic insights.[349 words]

  • Kilauea Volcano Builds Towards Explosive Eruption in Hawaii

    Kilauea Volcano Builds Towards Explosive Eruption in Hawaii
    2026/01/24
    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.
