GEOLOGY

Detailed explanation-1: -What are Seismic Waves? Seismic waves are caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake. Volcanic eruptions, explosions, landslides, avalanches, and even rushing rivers can also cause seismic waves.

Detailed explanation-2: -Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

Detailed explanation-3: -When an earthquake occurs shockwaves of energy, called seismic waves, are released from the earthquake focus. They shake the Earth and temporarily turn soft deposits, such as clay, into jelly (liquefaction).

Detailed explanation-4: -Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Detailed explanation-5: -Body Waves-Primary (P) & Secondary (S) Waves. Surface Waves-Rayleigh & Love Waves.
