M7.0 Earthquake Strikes Alaska–Canada Border — California on High Alert!

Описание: A detailed breakdown of the M7.0 Hubbard Glacier earthquake: what broke, why it happened where it did, and whether it echoes Yakutat Bay’s 19th-century doublet. This deep dive explains shallow strike‑slip rupture mechanics, the Fairweather/Queen Charlotte transform, the Yakutat microplate, aftershocks, landslide and local tsunami risks, and the limits of remote triggering (Cascadia, Aleutians).
