Soil Liquefaction Dangers During Earthquakes An earthquake brings a number of hazards: • Ground shaking and shifting can cause major damage‚ tearing apart houses‚ buildings‚ and roads. • Flooding that arises from broken water dams or river levees is another hazard. • Tsunamis‚ triggered by an undersea earthquake as well as seiches – waves coming from lakes shaken by a temblor – can submerge whole communities‚ sweep away edifices‚ topple trees and drown people. • Fire is another seismic hazard

Causes of Soil Erosion Amanda Brown Environmental Science 136 Rainfall and runoff is a water erosion problem also known as splash erosion. This is the first stage in the erosion process. The impact of rainfall drops on the soil surface can break down soil aggregates as the impact of falling raindrops breaks up the topsoil. This erosion is caused by long lasting and less intense storms. Runoff can occur whenever there is excess water on a slope that can’t be absorbed into the soil or trapped

It is a compilation of essays ranging from 1 1/2 to 5 pages long. Most
