An analysis of very low frequency earthquakes reveals a fragment of an old tectonic plate moving under the North American plate at the Mendocino Triple Junction 🌍🔍✨🗺️ Read Full Article #EarthquakeAnalysis #TectonicPlates #MendocinoTripleJunction #GeologyResearch…
📍 Seismologists have developed a new model of the complex area where the San Andreas fault meets the Cascadia subduction zone, using data from tiny, undetectable earthquakes. This region is a potential source of major, destructive earthquakes.
🗓️ Published Jan. 15 in Science, the research by the U.S. Geological Survey, UC Davis, and the University of Colorado Boulder reveals that the tectonic plate interactions are far more intricate than previously understood.
🧠 The new model includes five moving pieces, not just the three plates traditionally recognized. This includes a chunk broken off the North American plate and a rock fragment called the Pioneer fragment being pulled beneath the North American plate.
⚡ This enhanced understanding helps explain anomalies like a magnitude 7.2 earthquake in 1992, which occurred at a shallower depth than anticipated due to a revised view of the subducting plate's location.
