The most destructive earthquakes in history – Lisbon, Chile, Japan, Indonesia. How undersea quakes trigger tsunamis that can cross entire oceans. Why predicting earthquakes is so difficult – and what early warning systems can do. What megaquakes are, and why scientists fear the Cascadia Subduction Zone. Quakes beyond Earth – marsquakes, moonquakes, and icy moons with cracking surfaces. 🌌 Earthquakes are more than disasters. They’re a reminder that our planet is alive, restless, and constantly reshaping itself. #Earthquake #HowItWorks #ScienceExplained #Tsunami #Megaquake #Seismology #Documentary
