It highlights the contributions of the Geological Survey of India. In the nineteenth century itself, laid the foundations of scientific study of earthquakes in India and of the plate tectonic theory, which came to be finally proposed around 1960. This book gives the deep knowledge about earthquake. At what condition earthquake occur and also cause of earthquake, seismic zones of earthquake. This entire occurrence we have to convey when we have to read this book. Richter’s magnitude scale for earthquake is an instrumentally measured scale and is a measure of the amount of force released at the earthquake source. It is calculated from the amplitude measured by a standard Wood- Anderson seismograph and corrected in terms of a seismograph supposed to be kept at a distance of 100km from the epicenter. We give message to all readers to read this book and think about its precautions and how it can be controlled in future.
