 Geological activity across the United States has been dynamic this past week, with several notable updates from both volcanic and seismic research communities. According to the United States Geological Survey, volcanic activity at Hawaii’s Kilauea volcano remains closely monitored. As of mid-June, the Halema‘uma‘u eruption is paused, though summit inflation continues and low-level seismic tremor has persisted. The USGS notes that a new fountaining phase, part of Episode 26, could begin imminently depending on summit inflation rates. Overnight glow and intermittent spatter have been reported at the vents, signaling the possibility of renewed eruptive activity in the coming days. This ongoing situation underscores the need for continued vigilance around Kilauea, a volcano with a complex and active history.

Turning to the mainland, the USGS also highlighted recent developments at Yellowstone Caldera. In May, 119 earthquakes were reported, with the largest reaching magnitude 2 point 7. While these events remain well below hazardous levels, researchers continue to closely watch hydrothermal features. Notably, on May 31, Black Diamond Pool in Biscuit Basin experienced a small eruption, an event captured on video by a newly installed webcam. This marks the first recorded eruption since a significant hydrothermal explosion in July 2024, offering new insights into the region’s geothermal dynamics and the utility of remote monitoring technologies.

In Utah’s Wasatch Fault region, recent research detailed in ScienceDaily has examined the structural vulnerabilities that contribute to earthquake risk. By analyzing fault rock textures and conducting laboratory experiments, scientists have uncovered why this fault is particularly susceptible to seismic activity. These findings are especially relevant for the densely populated Wasatch Front, where earthquake preparedness continues to be a high priority.

Elsewhere in the western United States, hydrologists have determined that much of the region’s spring runoff is older than previously thought. A new study shows that streamflow out of mountain ranges is composed of snowmelt that has spent an average of five years underground before emerging. This challenges traditional understandings of seasonal water cycles and has significant implications for water resource management in the face of prolonged droughts.

On the global stage, geologists are preparing for upcoming international conferences such as the European Current Research on Fluid and Melt Inclusions in Turin, Italy, and the International Congress of Applied Geology in Cordoba, Argentina, where new research and collaborative efforts will be discussed. These gatherings reflect ongoing commitments to advance geological understanding worldwide.

Overall, recent developments highlight the interplay between natural processes and human observation, with advances in technology and research refining our knowledge of volcanic hazards, seismic risks, and critical water resources within the United States and beyond.
