  • Kilauea Volcano Eruption Looms as Scientists Monitor Inflation and Precursory Signs

    Kilauea Volcano Eruption Looms as Scientists Monitor Inflation and Precursory Signs
    2025/09/17
    Scientists are closely monitoring volcanic activity at Hawaii’s Kilauea volcano where the United States Geological Survey reports summit inflation continues and the likelihood for a new eruptive episode is growing. The latest signals include visible glow from the north and south vents, and gas pistoning cycles causing minor overflows from the crater, considered precursory signs ahead of full-scale lava fountaining. Models suggest that this eruptive sequence, known as episode thirty-three, could begin between September seventeenth and twentieth. The Uekahuna tiltmeter at the summit has recorded significant inflation since the previous eruption episode ended, indicating ongoing magma accumulation beneath the volcano. These observations come less than three weeks after episode thirty-two ended, which saw dramatic lava fountains up to five hundred feet high from the north vent according to the US Geological Survey. Activity at Kilauea remains at a “watch” alert level and aviation color code “orange.”

    Turning to Alaska, the United States Geological Survey’s Alaska Volcano Observatory has issued updates for the Great Sitkin Volcano, where an eruption is still ongoing. The persistent activity at Great Sitkin has included lava effusion and low-level ash emissions, continuing to pose local aviation hazards and reflecting the highly dynamic volcanic landscape of the Aleutians.

    Elsewhere in the United States, a new round of geologic hazard surveys is underway in the Northeast. The United States Geological Survey just launched low-level helicopter flights across Connecticut and Massachusetts to map bedrock geology and understand regional hazards, including the risks posed by the mineral pyrrhotite in local foundations. This study aims to aid infrastructure safety and inform building practices in pyrrhotite-risk regions.

    Globally, anticipation is building within the geoscience community for the Sixth World Congress on Geology and Earth Science, scheduled for later this month in Berlin, Germany. The upcoming sessions will address a variety of emerging topics, including environmental geoscience, geohazards, geological risk assessment, and the use of artificial intelligence in mapping and hazard prediction. Presentations will highlight new methods for detecting fracture displacement in rocks, advances in remote sensing using uncrewed aircraft, and research linking mercury contamination in groundwater to oil and gas activities.

    In the realm of discovery, new remote sensing work beneath Antarctica has revealed a previously unknown network of over three hundred massive submarine canyons sculpted by glaciers. Meanwhile, in the Canadian Yukon, geologists using satellite and drone technology have identified a dormant fault line, the Tintina fault, as a major earthquake risk after uncovering evidence of past seismic activity.

    Overall, the past week’s news points to heightened volcanic monitoring in the United States, new efforts to assess geologic hazards affecting communities, and significant international research collaboration improving our understanding of both ancient and modern geologic processes.

  • Volcanic Eruptions and Hidden Reservoirs: Unraveling the Mysteries of U.S. Geology

    Volcanic Eruptions and Hidden Reservoirs: Unraveling the Mysteries of U.S. Geology
    2025/09/13
    The past week has seen several significant developments in geology across the United States. According to the U.S. Geological Survey, intense volcanic activity continues at Kilauea in Hawaii. The most recent eruption episode, number thirty-two, ended abruptly on September second after more than thirteen hours of continuous lava fountaining. During this episode, lava covered nearly half the floor of Halemaumau crater. Scientists at the Hawaiian Volcano Observatory report that seismic and ground movement data indicate another episode of lava fountaining is likely to begin between September nineteenth and twenty-third, though this could be delayed if the underground magma pressure decreases. This ongoing series of episodic eruptions, which started in December twenty twenty-four, is closely monitored because of its unusual pattern and rapid fluctuations between inflation and deflation at the summit region. These events provide scientists with vital insights into how volcanic systems behave, recharge with magma, and eventually erupt.

    Elsewhere in the United States, geologists have made an unexpected discovery beneath the Yellowstone supervolcano in Wyoming. Researchers from the Deep Wyoming Project reported a hidden layer beneath Yellowstone, detected as a seismic anomaly. This previously unknown reservoir sits below the main magma chamber and appears to contain a strange mix of partially molten rock and various minerals. According to the project update on September seventh, this feature could help explain unusual patterns in earthquake activity and gas emissions observed in the area over the past year. Understanding this subterranean structure may also improve eruption forecasting and long-term hazard assessment for the Yellowstone region.

    In Colorado, the Colorado School of Mines is hosting an international summit on mining and resource geology from September twelfth to thirteenth. This event brings together exploration geologists, policymakers, and industry leaders to address challenges in securing stable mineral supply chains. Featured topics include advances in geological fieldwork, the impact of new mapping technologies, and how geology informs the search for critical minerals used in renewable energy and electronics.

    Looking internationally, scientists report discovery of tiny diatoms—microscopic algae—beneath Arctic sea ice, revealing new ecological processes that challenge previous assumptions about life in extreme cold. In Europe, researchers have uncovered colossal geological formations under the North Sea, prompting fresh questions about historical tectonic activity and sediment transport in that region.

    Back in the United States, researchers and policymakers alike are watching the evolving situation at both Kilauea and Yellowstone. Emerging patterns point to increasingly complex underground networks of magma and mineral reservoirs, which influence eruption risk, earthquake activity, and environmental impacts. These recent events highlight how rapidly advancing technology is reshaping the field of geology, enabling more detailed monitoring, better predictions, and a deeper understanding of how Earth’s dynamic systems operate.

  • "Uncovering Hawaii's Volcanic Wonders and Yellowstone's Evolving Geothermal Landscape: Geologists Reveal Insights"

    "Uncovering Hawaii's Volcanic Wonders and Yellowstone's Evolving Geothermal Landscape: Geologists Reveal Insights"
    2025/09/10
    Geologists from the United States Geological Survey recently completed fieldwork at the summit of Kilauea Volcano in Hawaii, assessing the aftermath of the latest episode of lava fountaining. The Hawaiian Volcano Observatory reported significant changes to the caldera rim, with scientists closely monitoring new cracks and lava deposits for signs of future activity. This comes after a period of heightened eruptions, underlining the importance of ongoing research into Hawaii’s active volcanic systems according to the USGS.

    In Yellowstone National Park, a new thermal pool was discovered in the Porcelain Basin area of Norris Geyser Basin. The United States Geological Survey noted that this feature likely emerged between late December 2024 and early February 2025, formed by explosive geothermal events that ejected silica mud and rocks. Measuring about thirteen feet across, this pool contributes to a pattern of increasing geothermal activity in the region, with old favorites like Old Faithful continuing to erupt regularly. Such phenomena are not only a tourist draw but also critical for understanding underlying tectonic and hydrothermal processes affecting the greater Yellowstone area, according to reports from Gizmodo and Geology.com.

    Another headline in recent geology news is the ongoing shrinkage of the Great Salt Lake in Utah. As the lakebed dries, scientists have begun to observe hidden springs and mysterious reed-covered mounds fed by groundwater. These discoveries suggest complex interactions between surface water, groundwater, and climate, prompting renewed interest in monitoring the health of inland water systems. According to ScienceDaily, these changes may also impact the long-term geology and ecology of the region.

    The Department of the Interior, working with the United States Geological Survey, has also released its draft 2025 List of Critical Minerals, outlining resources considered essential for national security and economic growth. The spotlight remains on rare earth elements, with Apple recently announcing a partnership with MP Materials, the operator of the Mountain Pass rare earth mine in California. This collaboration aims to boost the domestic supply chain for rare earth materials required for electronics and renewable energy technologies.

    Globally, the scientific community has celebrated breakthroughs such as Cambridge researchers solving the mystery of how volcanic activity once spanned vast parts of the North Atlantic, with ancient plate scars spreading Iceland’s mantle plume. Meanwhile, environmental concerns continue to mount in places like Southern California, where toxic leaks from barrels dumped decades ago have transformed sections of the ocean floor into hazardous zones. These findings underscore a growing awareness of the long-term impacts of human activity and natural processes on geological environments.

    With upcoming conferences like the Society of Economic Geologists meeting in Brisbane and major virtual events focused on geoethics, collaboration across borders is accelerating, promising further advances in the understanding of Earth’s dynamic systems and emerging geological risks.
