Puerto Rico learned this harsh lesson in 1918 when a massive wave killed 40 people. The Dominican Republic tsunami in 1946 was even more devastating, killing over 1,600 people. The Caribbean has a history that most Americans ignore. These aren’t ancient history campfire stories but urgent warnings of what could happen again. The fault systems remain active, steadily building pressure, waiting to release the next mega-killer wave.
