Earthquakes happen when there is a sudden release of energy in the Earth’s crust, usually caused by the movement of tectonic plates. These plates constantly shift, and when they get stuck, stress builds up until it is released as seismic waves, shaking the ground. The point inside the Earth where the earthquake starts is called the focus, and the point directly above it on the surface is the epicenter.
Earthquakes can vary in strength from small tremors to devastating events that cause damage and loss of life. Scientists use seismographs to detect and measure earthquakes, helping to understand their patterns and risks. Studying earthquakes is essential for building safer structures and preparing communities in vulnerable areas. Shutdown123
