P-waves
P-waves, or primary waves, are a type of seismic wave generated by earthquakes. They are the fastest seismic waves and travel through solids, liquids, and gases. When an earthquake occurs, P-waves compress and expand material in the direction they move, similar to how sound waves travel through air. This means they can be detected first by seismographs, providing crucial early information about an earthquake's occurrence. Because they can pass through various materials, studying P-waves helps scientists understand the Earth's internal structure, including its core and mantle.

P-waves, or primary waves, are a type of seismic wave generated during earthquakes. They are the fastest seismic waves and travel through the Earth, moving the ground in a push-pull motion, similar to how sound travels through air. P-waves can move through solids, liquids, and gases, making them the first waves detected by seismographs after an earthquake occurs. Their speed and ability to travel through different materials help scientists locate the earthquake's epicenter and understand the Earth's internal structure.
