概要

 Recent geological developments across the United States and globally reveal a dynamic planet undergoing significant changes. The U.S. Geological Survey reports that Yellowstone remains at normal background activity levels, though the geothermal system continues to display remarkable activity. In February 2026, the University of Utah Seismograph Stations detected 74 earthquakes in the Yellowstone region, with the largest measuring magnitude 2.4. A particularly intriguing development occurred in late 2024 and early 2025 when a curious new blue water pool formed in Norris Geyser Basin through a series of small explosions that excavated a small crater. Meanwhile, Steamboat Geyser produced one water eruption on February 27, while Echinus Geyser, quiet since 2020, erupted approximately 40 times during February alone. The U.S. Geological Survey is implementing updated Volcano Observatory Notices to Aviation beginning in early March 2026, following new standards established by the International Civil Aviation Organization to better communicate volcanic hazards to the aviation industry.

In the American West, Round Top Mountain in Hudspeth County near Sierra Blanca, Texas, has captured global geological attention as potentially the largest heavy rare earth element deposit in the United States and possibly the world. This lone rhyolite peak in the rugged West Texas desert represents a significant discovery for energy and technology sectors dependent on rare earth materials.

Internationally, Iceland faces imminent volcanic activity on the Reykjanes Peninsula. GPS data shows a massive dome-shaped bulge underground, with approximately 70 megaton of basaltic magma accumulating beneath the surface. Ground uplift has exceeded 40 centimeters, surpassing thresholds observed in previous eruptions. Scientists indicate that a fracture in the ground could occur at any moment, potentially creating a new volcanic eruption in the North Atlantic region.

Meanwhile, marine geology research published in February 2026 reveals that a hidden mantle plume beneath the Atlantic Ocean helped rip open the seafloor, creating the King's Trough, an underwater canyon system larger than the Grand Canyon. Marine geologists at GEOMAR explain that thickened, heated crust made the region mechanically weaker, allowing the plate boundary to shift preferentially at that location. Similar processes continue near the Azores, where the Terceira Rift is currently forming in another region with unusually thick oceanic crust.

Additionally, recent research ties marine volcanic plateaus to at least four extinction events during the Triassic period, with detailed analysis of oceanic remnants in the Tibetan Plateau revealing how massive volcanic activity has shaped Earth's history. Global warming research suggests the Earth warmed approximately 0.35 degrees Celsius over the past decade, representing a nearly 75 percent increase compared to earlier measurements, demonstrating how climate change continues to influence geological processes worldwide.
