Hidden 'Razor-Sharp' Earthquake Line Reveals Alaska's Secret Microplate
Scientists have uncovered a 250-kilometer-long, 'razor-sharp' line of thousands of previously hidden tiny earthquakes beneath Alaska, a discovery that clearly outlines a secret, actively subducting microplate. This finding, published on June 4, 2026, in The Seismic Record, finally maps the precise edge of the Yakutat microplate as it dives under the larger North American Plate, giving us a clearer picture of Alaska's complex underground movements.
