10. Mention any two destructive effects of earthquakes.
Answers
Answer:
Ground shaking
Ground shaking is a term used to describe the vibration of the ground during an earthquake.
Ground shaking is caused by body waves and surface waves.
As a generalization, the severity of ground shaking increases as magnitude increases and decreases as distance from the causative fault increases.
Although the physics of seismic waves is complex, ground shaking can be explained in terms of body waves, compressional, or P, and shear, or S, and surface waves, Rayleigh and Love.
Surface Faulting
Surface faulting is the differential movement of the two sides of a fracture at the Earth's surface and can be strike-slip, normal, and reverse (or thrust).
Combinations of the strike-slip type and the other two types of faulting can be found.
Although displacements of these kinds can result from landslides and other shallow processes, surface faulting, as the term is used here, applies to differential movements caused by deep-seated forces in the Earth, the slow movement of sedimentary deposits toward the Gulf of Mexico, and faulting associated with salt domes
