Fragment of Lost Tectonic Plate Found Under Cascadia: Implications for San Andreas and Cascadia Faults
Discovery of a Hidden Plate Fragment A team of scientists has identified a fragment of a long-lost tectonic plate sliding beneath the North American continent in the southern Cascadia subduction zone. The discovery, based on seismic imaging and geological samples, suggests that the region’s tectonics are more complex than previously understood. The fragment appears to…

Space-Based Observations Reshape Understanding of Tsunami Wave Behavior
Introduction: A New View from Space For years, scientists studying tsunamis relied on direct measurements from buoys, tide gauges, and coastal observations. Space-based observations, however, are now rewriting what we know about how tsunami waves travel across the ocean. The latest data show that tsunami wave behavior is more intricate than a single, smooth crest…

Remote Iranian Volcano Awakens: A 700,000-Year Silence Ends
Summary: A Quiet Giant Wakes A volcano in southeastern Iran has shown measurable uplift after nearly 700,000 years of dormancy. Using satellite data, researchers have detected a rise of about 3.5 inches (9 centimeters) over ten months. While the movement might seem modest, it signals potential pressure changes beneath the surface, prompting scientists to monitor…

Remote Iranian Volcano Awakens: 700,000-Year Silence Ends as Ground Rises
Rising Signals: A Quiet Giant Awakens A remote volcano in southeastern Iran has begun to visibly lift from its long rest, rising about 9 centimeters (roughly 3.5 inches) in just ten months. While this may sound modest, scientists say the movement could signal the early stages of magmatic pressure building beneath the surface. The discovery,…
