¿Qué es un terremoto?

Earthquakes are sudden, violent vibrations of the Earth's crust caused by tectonic plate movements. They occur at fault lines where pressure builds up and is released, creating seismic waves. These waves are measured using a seismograph and the Richter scale. Earthquakes can cause massive destruction, trigger fires, landslides, and tsunamis, and are followed by aftershocks. Despite their impact, predicting earthquakes remains a challenge, making them a persistent threat.
