Earthquakes: Nature's Warning Signs and the Power of Tectonic Plates

The video explores how animals might sense earthquakes before they occur, possibly due to pressure changes or electrical signals. It discusses the Ring of Fire, where most earthquakes happen due to tectonic plates. The video includes trivia about the number of detectable earthquakes annually and highlights hotspots like Alaska and the San Andreas Fault. It emphasizes the importance of engineering for earthquake resilience and concludes with a reminder of the interconnectedness of natural forces and human impact.
