# Alaska’s hidden plate boundary revealed by 1,750 tiny quakes 2026-08-14T09:06:09+00:00 | World & Diplomacy | Indian Opinion Desk Corroboration: 1 independent outlet The Times of India reports that scientists have discovered a hidden geological feature under south-central Alaska using a machine learning system to analyse years of seismic data. The study, published in The Seismic Record and led by seismologist Meghan Miller of the Australian National University, identified a linear cluster of approximately 1,750 small, previously undetected earthquakes stretching 250 km. The cluster traces the exact edge of the Yakutat microplate, a thick slab of oceanic crust caught in the collision between the Pacific and North American plates. Researchers believe this newly mapped boundary may help explain the origin of the magnitude 7.9 Denali earthquake that struck the Alaskan interior in 2002, as its location aligns closely with the quake's initiation point. Confirming the connection, however, will require further computational modelling. ## Coverage - timesofindia.indiatimes.com Tags: Alaska, Denali fault, earthquakes, geology, machine learning, Yakutat microplate Canonical: https://indianopinion.org/alaskas-hidden-plate-boundary-revealed-by-1750-tiny-quakes/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
