Seismic Wave Propagation

Seismic wave propagation refers to how energy from earthquakes travels through the Earth’s layers. When an earthquake occurs, it releases energy that moves outward in waves, similar to ripples on water. These waves travel through the Earth's solid materials, changing speed and direction depending on the type of material they pass through. There are primarily two types: body waves, which go through the Earth's interior, and surface waves, which move along the surface. Understanding how these waves propagate helps scientists locate earthquakes, assess their strength, and study the Earth's internal structure.
