 Recent developments in geology reveal significant findings about Earth's dynamic systems and critical mineral resources. The Hawaiian Volcano Observatory reported that Episode 36 of the ongoing Halemaʻumaʻu eruption at Kīlauea ended on November 9 after approximately five hours of high lava fountains. The south vent produced fountains reaching about 1,200 feet in height while the north vent reached approximately 750 feet. Following the eruption, scientists observed only minor glow from the south vent overnight, with both vents fuming the next morning. Sulfur dioxide emissions remained at background levels between 1,200 and 1,500 tonnes per day. Observatory analysis suggests the next eruptive episode is at least a week away, with more than one week likely before fountaining resumes based on the amount of deflation observed during this episode. The current eruption, which began on December 23, 2024, has been characterized by episodic lava fountaining not observed in any eruptions since the 1983 to 1986 episodic fountains at the beginning of the Puʻuʻōʻō eruption.

On the national minerals front, the U.S. Geological Survey released an updated critical minerals list on November 6. Uranium has been reinstated to the list after being excluded from the 2022 version, bringing the total number of critical minerals to 60. This reinstatement reflects growing nuclear energy demands in the United States. Meanwhile, researchers have identified a significant issue with American resource management. Scientists discovered that the United States already mines all the critical minerals needed for energy, defense, and technology, yet most are being discarded as mine tailings. Minerals including cobalt, germanium, and rare earth elements are lost in massive amounts during mining operations.

Additional research published in recent weeks revealed new insights into continental geology. Scientists discovered that continents do not merely split at their surfaces but also peel from below, feeding volcanic activity in oceans. Simulations demonstrate that slow mantle waves strip continental roots and push them deep into oceanic regions, explaining previously mysterious patterns of volcanic activity.

International geological conferences are convening this month to address these discoveries and other pressing concerns. The 14th World Conference on Earth Science and Geology is taking place November 13 and 14 in Paris, France, bringing together geologists and earth scientists to discuss climate change, environmental science, and advanced technologies for addressing geological hazards. These converging developments underscore how Earth's geological systems continue to reshape our understanding of planetary processes while presenting both challenges and opportunities for resource management and hazard mitigation.
