The Caribbean's Next MEGATHRUST Earthquake Scientists Are Watching

Scientists are watching the Caribbean plate boundary because the region contains more than one way to produce a major earthquake and tsunami. This version follows the difference between Venezuela's strike-slip quake and the deeper megathrust threat under the Puerto Rico Trench, Hispaniola, and the Lesser Antilles Arc. The episode explains subduction zones, tsunami generation, pre-Columbian tsunami deposits, coral microatoll strain evidence, the 1918 Puerto Rico tsunami, the 1946 Dominican Republic earthquake, the submarine landslide wildcard, and why near-source tsunami evacuation planning matters for residents and visitors. 00:00 Venezuela reopens the warning 01:20 Why this was not the feared megathrust 02:10 What megathrust earthquakes do 03:05 Strike-slip faults versus subduction zones 04:10 Puerto Rico Trench and Hispaniola 05:20 1918, 1787, and buried tsunami evidence 06:25 A possible Atlantic-wide tsunami source 07:35 Lesser Antilles subduction zone 08:55 Coral microatolls reveal silent strain 10:10 Older tsunamis across the island arc 11:05 Hispaniola and the 1946 disaster 12:20 Modern coastal exposure 13:30 Caribe Wave and regional preparation 14:45 Submarine landslide wildcard 15:50 Recent Caribbean earthquake activity 16:55 Why no one can give a date 18:00 What residents and visitors should know 19:05 What scientists are watching next
