East Coast – The Sleeping Giant Most People Ignore

The East Coast faces equal danger from underwater landslides and distant earthquakes. However, the main threat lurks on the continental shelf, where earthquakes around magnitude 4.5 could trigger underwater landslides. The 1755 Lisbon earthquake proved how far tsunamis can travel, sending lethal waves across the Atlantic to North America. Caribbean earthquakes pose a major threat to Florida and the Southeast. The Caribbean fault system runs 2,000 miles and could affect over 35 million people.
