Using induced earthquakes to prevent large magnitude natural earthquakes.
The tectonic plates movement cause faults in the earth crust, which are the center of earthquakes and volcanic activity. Rock blocks on two sides of a fault accumulate elastic energy during many years and release it instantly in the form of an earthquake. It is possible to eliminate the risk of earthquakes by preventing the accumulation of the rocks elastic energy. Generating large shocks in the ground ab

A new study suggests that the hobbits, a diminutive people whose remains were found on the Indonesian island of Flores in 2003 and 2004, were real humans after all.

The green, white and blue revolutions gave us food security. The high yielding varieties and new technologies were webbed with chemical farming. Even today we have critical gaps existing in production of food through technology use and at traditional farmers field. The chemical farming resulted in the soil degradation, water pollution, soil erosions and soil salinity .By now we face land degradation problems in 173 million hectares which is around 53% of cultivated land.
