Seismic waves are waves of energy that are generated by earthquakes, volcanic eruptions, and other sudden movements of the Earth's crust. These waves travel through the Earth's layers, including the crust, mantle, and core, and can be detected by instruments called seismometers.
Seismic waves come in two main types: body waves and surface waves. Body waves, also called primary waves, travel through the Earth's interior and are the fastest type of seismic wave. They can move through solid rock, liquid, and gas, and are able to pass through the Earth's core. Surface waves, also called secondary waves, travel along the surface of the Earth and are slower than body waves. They are responsible for much of the damage caused by earthquakes, as they can cause the ground to move up and down or side to side.
Seismologists study seismic waves to learn about the structure and composition of the Earth's interior, and to understand the processes that cause earthquakes and other geological events. They use the information gathered from seismic waves to develop models of the Earth's interior, to predict the likelihood and impact of future earthquakes, and to help design structures that are able to withstand the effects of seismic activity.
