 Geology news this week in the United States has been dominated by new volcanic activity, advances in natural resource assessments, and ongoing research on Earth’s dynamic systems. The United States Geological Survey reported that the Kilauea volcano in Hawaii remains active. On November seventeenth, Observatory staff conducted fieldwork inside the closed area of Hawaii Volcanoes National Park. They observed fresh evidence of hazards left by the recent episode of vigorous lava fountaining. This activity underlines Kilauea’s status as one of the world’s most closely monitored volcanoes. According to VolcanoDiscovery and the USGS, the eruption continues with intermittent explosive and effusive activity, maintaining elevated risk levels for the region’s inhabitants and park infrastructure.

Elsewhere, the Smithsonian Global Volcanism Program noted that both Kilauea in Hawaii and Great Sitkin in the Aleutian Islands remain in a continuing eruptive state. The Smithsonian points out that globally, forty-four volcanoes are currently classified as in eruption, with approximately twenty showing daily activity at any time. Worldwide, major volcanic events include continuing eruptions at Italy’s Mount Etna, Indonesia’s Semeru and Ibu volcanoes, and Guatemala’s Fuego. These highlight geothermal instability not only in the United States but across volcanic belts worldwide, reflecting persistent geological hazards and research opportunities.

Beyond volcanoes, resource geology made headlines as the United States Geological Survey announced significant progress in mineral and energy resource assessments. On November twentieth, the USGS revealed new estimates for the Niobrara formation, stretching across southwestern Wyoming and northwestern Colorado. This assessment indicates approximately seven hundred three million barrels of oil and nearly six trillion cubic feet of gas may be undiscovered in this unit. A similar report for the Phosphoria system, also spanning Wyoming and Colorado, details an estimated three million barrels of oil and over six hundred billion cubic feet of gas. These studies reflect the current government and scientific focus on boosting domestic energy and mineral supplies, particularly from older and inactive mine sites.

Meanwhile, the ongoing melting of glaciers continues to concern geologists worldwide. ScienceDaily describes new findings on how hidden underwater waves, driven by iceberg calving in Greenland, are accelerating glacial melt at an unprecedented rate. Satellite studies further reveal that the Hektoria Glacier in Antarctica underwent the fastest recorded modern ice retreat, demonstrating the rapid sensitivity of ice sheets to oceanic and atmospheric changes.

November also marked the tenth anniversary of the UNESCO Global Geoparks initiative. As highlighted by the Global Geoparks Network, these parks continue to play a crucial role in conserving the planet’s geological heritage and supporting research, education, and sustainable tourism, both in the United States and globally. The recent developments underscore geology’s vital role in hazard monitoring, resource management, and environmental stewardship, with American scientists and agencies at the forefront of these efforts.
