Boosting Domestic Minerals, Monitoring Volcanic Risks, and Coastal Resilience: Evolving U.S. Geological Priorities

The United States Geological Survey issued its final 2025 List of Critical Minerals on November seventh, expanding the roster to sixty key materials essential for national security, supply chains, and industry. According to the USGS announcement, this update responds to the Energy Act of 2020 and incorporates executive orders on unleashing American energy and reinvigorating clean coal, adding uranium, metallurgical coal, potash, silicon, copper, silver, rhenium, lead, and retaining boron, arsenic, tellurium, and phosphate after interagency reviews from Defense, Energy, Agriculture, and others. The methodology, detailed in USGS Open-File Report 2025-1047, analyzed over twelve hundred disruption scenarios across eighty-four commodities and four hundred two industries, prioritizing economic impacts from foreign trade risks and single-point domestic failures. Interior Secretary emphasized the list's dynamic nature, with biennial updates planned based on supply shifts, demand, and policy.

In Hawaii, Kilauea volcano's summit eruption paused as of December seventeenth, per the USGS Hawaiian Volcano Observatory notice. Intermittent glow persists in the south vent of Halemaumau crater, with tremor spikes, following spattering lava observed deep in the north vent on December second during an overflight. Yellow sulfur deposits surround the vents, formed when sulfur dioxide and hydrogen sulfide gases react and cool at the surface, as captured in USGS video by geologist K. Mulliken. Eruption activity continued through December sixteenth, highlighting ongoing monitoring in the islands.

A UMass Amherst and Massachusetts Geological Survey study released December sixteenth reveals ocean sediments are vital for northeastern United States salt marshes to survive sea-level rise. Researchers describe it as a wake-up call on oceans' role in delivering sediments that help marshes keep pace with rising waters along coasts from Maine to Virginia.

At the American Geophysical Union Annual Meeting in New Orleans this week, volcanologist Pavel Izbekov from the Alaska Volcano Observatory presented research on crystal clusters in magma from Bogoslof volcano's 2016-2017 eruptions. Diffusion chronometry in clinopyroxene, plagioclase, and amphibole crystals dated a critical decompression event to early March 2017, matching seismic and sulfur dioxide spikes, offering a new tool to forecast eruptions by reading magma history in mineral zones.

These developments underscore emerging patterns: bolstered domestic mineral strategies amid global risks, persistent volcanic hazards in the Pacific, coastal resilience tied to ocean dynamics, and advancing crystal-based eruption predictions, all shaping United States geology priorities.
