The latest geological monitoring shows Kilauea volcano in Hawaii remains in a state of pause following Episode 19 of its ongoing Halemaʻumaʻu eruption, which ended on May 2, 2025, after nearly 8 hours of sustained lava fountaining at the north vent. According to the Hawaiian Volcano Observatory, the rapid rebound from deflation to inflation and continued weak tremor suggests another eruption episode is likely. This marks the 19th episode in the current eruption cycle that began in December 2024, with all activity confined to Hawaii Volcanoes National Park.
Meanwhile, earthquake activity continues across the United States. A 4.4 magnitude earthquake struck northern Los Angeles in the Highland Park area earlier this week. Another earthquake was reported northwest of Seattle near the US-Canada border. These events follow a pattern of seismic activity that has kept geologists busy monitoring fault lines along the West Coast.
The US Geological Survey recently announced funding opportunities for states to investigate critical minerals in mine waste. These projects will support data collection needed to evaluate mine waste as a potential domestic source of critical minerals, addressing supply chain vulnerabilities for materials essential to technology and defense industries.
In energy resource news, the USGS has released several assessments of undiscovered oil and gas resources across the country. Their findings indicate approximately 35.8 trillion cubic feet of undiscovered gas along the Gulf Coast, enough to supply the nation for 14 months. Additional assessments revealed 11 trillion cubic feet of gas and 366 million barrels of oil in Texas Maverick Basin, 47 million barrels of oil in upper Paleozoic Reservoirs in Wyoming and southern Montana, and 61 million barrels of oil remaining in the historic Los Angeles Basin.
Looking ahead, the geological community is preparing for several important upcoming events. The International Union of Geological Sciences will host its Initiative on Forensic Geology conference in Rome from May 21-23, 2025. This follows the European Geosciences Union General Assembly that concluded in Vienna on May 2, bringing together earth scientists from around the world to discuss the latest research and findings in the field.
Beyond geological formations, concerning environmental trends continue, with a recent study published in Science finding that 22 percent of butterflies in the United States have disappeared between 2000 and 2020, highlighting the changing landscape and ecological impacts that geologists and environmental scientists are tracking.
