Seattle's Double Earthquake Threat: Two Fault Lines Capable of a Megaquake

Scientists have discovered two fault lines in the Puget Sound region, including the Seattle Fault Zone and the Saddle Mountain Fault Zone, capable of causing a 7.8-magnitude earthquake similar to the one that occurred 1,100 years ago. This ancient megaquake triggered landslides and a local tsunami, posing a significant threat to the region's four million residents. A potential earthquake of this magnitude could result in the loss of over 1,600 lives, destruction of nearly 10,000 buildings, and economic losses of $50 billion. The study suggests that simultaneous ruptures of these fault lines are possible, emphasizing the need for preparedness and mitigation measures in the Seattle area.
