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

I’ve just finished reading Jeff Nitzkin’s new book Toil...ing. Instead of reading it in one go like I prefer to read a book for review‚ life had me put it down and pick it up several times over the course of the month.

Land pollution is one of the gravest kinds of pollutions. I say so because we do not realize when and how we pollute land due to different things we do and decisions we take.

We know when our actions cause water pollution‚ for we can see for ourselves the quality of the water worsening. Similarly noise‚ light‚ visual pollution can all be monitored‚ because we can all see or sense these kinds of pollution
