Line of tiny quakes reveals Alaska's hidden Yakutat microplate

Thousands of tiny earthquakes arranged in a straight line beneath the Denali Fault reveal the edge of the Yakutat microplate, suggesting this buoyant block concentrates seismic energy and may drive uplift of the Alaska Range and related volcanism; researchers deployed new seismometers to map the offshore edge, with findings published in The Seismic Record (June 4, 2026).
