Across the United States this week, geology remains firmly in the national spotlight with significant conversations and events focusing on sustainable energy, mineral resources, seismic activity, education, and new mapping tools. According to Southern Illinois University, Earth Science Week is underway through October 18, celebrating the theme “Energy Resources for Our Future.” Programming at the Carbondale campus is highlighting how the transition to clean energy depends on securing critical minerals like rare earth elements, cobalt, and lithium, many of which are essential to technologies from smartphones to solar panels and electric vehicles. Experts discussed how the U S faces challenges in both sourcing and sustaining supplies of these minerals, and how innovative fields like agrivoltaics—which entails integrating solar panels with agriculture—could address both energy production and land stewardship in Southern Illinois and beyond. The urgency of expanding renewable energy infrastructure in the Midwest is matched by a public campaign to increase awareness of geological resources, with SIU’s Department of Geology hosting public clinics to help people identify rocks and minerals of local and scientific significance, inviting the broader community to become engaged in geology.
On the national level, the United States Geological Survey has taken major steps this month by releasing a draft of its 2025 List of Critical Minerals. The new methodology, developed in consultation with the U S Department of the Interior, identifies 54 minerals considered essential to the nation’s economic and strategic security, further emphasizing the importance of mineral exploration, recycling, and inventory of both active and abandoned mine sites. In parallel, the USGS unveiled a comprehensive, interactive national geologic map. This digital tool allows researchers and the public to explore detailed geological features across the country, promising to fuel new research and education initiatives.
Meanwhile, geological hazards remain under close observation. Recent minor seismic events were registered in California’s Geysers region, a reminder of the state’s constant tectonic activity according to the Volcanic Discovery earthquake reports. Across the country, International ShakeOut Day brought earthquake preparedness activities to thousands of U S students, especially in the Central United States, where regions such as southern Illinois have a complex seismic history. These drills are part of a growing commitment to seismic safety and awareness.
Globally, significant earthquakes have struck in Costa Rica’s North Pacific Ocean area with a magnitude of 5 point 9, while volcanic activity at Guatemala’s Fuego volcano has been monitored closely with eruptions sending shockwaves and giant boulders skyward, as reported by Volcano Discovery and live video streams.
Returning to developments in research and outreach, the Geological Society of America is convening its annual meeting in San Antonio, Texas, this week, where leaders are addressing the future of field education, the integration of new technology in geoscience, and the need to inspire a new generation of earth scientists. Together, these national and international efforts reflect the interconnected nature of geology, resource management, natural hazards, and education as the United States and the world grapple with both the risks and opportunities beneath our feet.
