Seismographs logged a magnitude 2.1 earthquake 94 km N of Yakutat, Alaska with origin time 20:50 UTC on May 27, 2026. It arrived roughly 2 hours after a larger magnitude 2.5 mainshock in the same 20 km area, placing it within the typical aftershock window. This very shallow event was close enough to the surface that even modest magnitudes can produce significant local shaking.
