Great Sitkin Volcano Erupts in Alaska, Yellowstone Remains Stable: USGS Updates and Upcoming Geological Events

Lava continues to erupt from the summit crater of Great Sitkin Volcano in Alaska, with elevated surface temperatures observed through satellite imagery throughout the week as reported by the United States Geological Survey. This site has seen persistent volcanic activity, but no imminent threat to nearby communities has been identified. In contrast, Yellowstone Caldera in Wyoming remains at normal background levels. The most recent update for July notes 60 detected earthquakes in June, the largest registering magnitude two point seven, and a webcam documented a minor eruption of Black Diamond Pool. Summer deformation data continues to indicate the expected seasonal pause in caldera subsidence, and overall volcanic risk in Yellowstone remains low according to the USGS.

Meanwhile, celebration and outreach remain essential parts of the geological calendar. Bryce Canyon National Park in Utah is hosting the annual Geology Festival, known locally as Geo Fest, on July eighteenth and nineteenth. The event highlights the spectacular rock formations of the park and features hands-on educational experiences designed to foster public appreciation for Earth’s dynamic processes, as outlined by the National Park Service.

Mapping efforts have yielded valuable data on Earth’s surface and resources. The United States Geological Survey released the latest addition to the National Land Cover Database, marking forty years of comprehensive, raster-based land use analysis. The newly updated dataset provides annual records of land cover types, change, and impervious surface metrics across the lower forty-eight states. This collection offers researchers and policymakers deeper insight into ongoing landscape changes driven by natural forces and human development.

On the energy sustainability front, a historic milestone was recently achieved with the creation and public release of the first-ever national map detailing the potential for geologic hydrogen within the contiguous United States. According to the US Geological Survey, this groundbreaking map outlines regions with geologic conditions favorable for natural hydrogen deposits, particularly across Kansas, Iowa, Minnesota, Michigan, the Four Corners states, stretches of the California coast, and the Eastern seaboard. Long considered an improbable resource, geologic hydrogen now emerges as a promising clean energy candidate. Preliminary estimates suggest the United States may contain vast reserves, with an energy content potentially double that of the world’s proven natural gas reserves.

Internationally, key geoscience conventions are taking place, including the upcoming Fourth International Congress on Earth and Geological Sciences in Paris and workshops on heritage stone in Dublin. These events, as promoted by organizations such as the International Union of Geological Sciences, illustrate global momentum in advancing geological research and collaboration.

Across the United States, from active volcanoes in Alaska to national land cover assessments and groundbreaking hydrogen resource mapping, geology continues to offer new insights into both hazards and sustainable opportunities while connecting communities through science and education.
