It also said Tuesday's quake was roughly 150 miles from that zone. Daily MailR “Scientists have long warned that the zone is overdue for a catastrophic event”“The earthquake on September 29 occurred roughly 150 miles from the Cascadia Subduction Zone” Read at Daily Mail ↗ BNO News mentioned Cascadia only briefly, noting that the Seattle area faces risks from faults beneath Puget Sound and from the offshore subduction zone.
