Earthquakes

Earthquakes are sudden, violent movements of Earth's Crust caused by the release of accumulated Stress along geological faults or at plate boundaries. When tectonic plates shift, they snap free from friction, unleashing energy in waves that radiate outward—sometimes catastrophically.

The Richter Scale measures earthquake magnitude by the amplitude of seismic waves, while the Moment Magnitude Scale gauges total energy released. Seismologists use networks of sensitive instruments called seismometers to detect and map these events.

Most earthquakes occur at Subduction Zones or Transform Faults, where plates collide, slide, or separate. Aftershocks—smaller tremors following the main event—can persist for weeks. Some earthquakes trigger Tsunamis when they displace ocean water, posing distinct coastal hazards.

Understanding earthquake mechanics informs Building Design, early warning systems, and Geological Heritage preservation. Earth experiences roughly one major earthquake daily, though most strike remote regions. The study of earthquake patterns reveals deep truths about planetary dynamics and Geological time.

Earthquakes have shaped human civilization, influencing where cities grow and how we design infrastructure for resilience.
