Why Did One Panama Earthquake Put Nine Countries on Tsunami Alert

Описание: A magnitude 7.7 earthquake struck southern Panama and quickly triggered tsunami alerts across nine countries. Within hours, most of those alerts were pulled back — but that does not mean the warning was wrong.

This report explains why the quake was so alarming, how shallow depth intensified the shaking, what happened in Herrera, Veraguas, Los Santos, Penonomé, Panama City and nearby countries, and why the tsunami system sends warnings before the ocean confirms a wave. It also breaks down deep-ocean sensors, tide gauges, tsunami speed, historical disasters, aftershocks, Panama's shutdown, the PAGER red alert, and why the Panama Canal matters far beyond Panama.
