MCQ Detailed View

P-waves, or Primary waves, are the fastest type of seismic waves generated during an earthquake. They are called "primary" because they are the first waves to arrive at a seismic recording station after an earthquake occurs.

P-waves are compressional waves, meaning they compress and expand the material through which they travel. They can move through both solid rocks and fluids, unlike S-waves (secondary waves) which can only move through solids.

Key Facts about P-Waves:

• Associated with: Earthquakes


• Type of Wave: Seismic / compressional


• Speed: Fastest seismic waves, first to be detected


• Propagation: Travels through solids, liquids, and gases


• Role: Helps in earthquake detection and analysis

P-waves are essential for understanding the internal structure of the Earth and play a crucial role in early warning systems for earthquakes, giving a few seconds of warning before more destructive waves arrive.
