different effects of earthquake in detail (class 11)
Answers
Answer:
Ground shaking is the most familiar effect of earthquakes. It is a result of the passage of seismic waves through the ground,
Below is an image of the Cypress viaduct which was part of Interstate 880 in Oakland, CA. The upper level of the two-level structure has collapsed onto the lower level as a result of failure of the support columns. The columns failed partially in response to ground shaking from the 17 October 1989 Loma Prieta earthquake amplified by loose sediments near the Oakland waterfront. 41 people were killed in the collapse.
Explanation:
Ground Rupture
Landslides are caused by earthquakes both by direct rupture and by sustained shaking of unstable slopes
Tsunamis, which are popularly -- and incorrectly -- known as ``tidal waves,'' are a grave hazard to many parts of the world, particularly around the Pacific Ocean basin. Tsunamis are a series of water waves caused when the seafloor moves vertically in an earthquake
Liquefaction and subsidence of the ground are important effects which often are the cause of much destruction in earthquakes, particularly in unconsolidated ground. Liquefaction is when sediment grains are literally made to float in groundwater, which causes the soil to lose all its solidity. Subsidence can then follow as the soil recompacts.
Earthquakes are not Evil!

Answer:
The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Fires are probably the single most important secondary effect of earthquakes.
