seismic waves

Seismic waves are energy waves that travel through the Earth, primarily generated by earthquakes or volcanic activity. There are two main types: body waves and surface waves. Body waves include P-waves, which are fast-moving and compressional, and S-waves, which are slower and shear in nature. Surface waves travel along the Earth's surface and usually cause the most damage during earthquakes. Scientists study these waves to understand the Earth's internal structure and to predict seismic activity, helping to mitigate risks associated with natural disasters.
