9.0 magnitude Cascadia subduction zone megaquake threatens Seattle with 14,000 deaths, $134bn losses, and a tsunami.
Experts warn that the Pacific Northwest, particularly Seattle, faces a significant risk of a megaquake, known as the "Big One," from the Cascadia subduction zone. This potential 9.0 magnitude earthquake could result in up to 14,000 deaths, damage over 618,000 buildings, and lead to $134 billion in economic losses. A tsunami with waves reaching eight stories high could follow. Despite years of preparation, authorities acknowledge that full readiness is unattainable.
