Introduction

This chapter mentions about need of a book on different seismological aspects of the devastating Nepal earthquake of 2015 for Nepal, India and other earthquake-prone countries of the World. It informs that how India has been affected by large earthquakes in Nepal, hence, knowledge about the Nepal 2015 earthquake is of great interest to India. It is also important for all the developing countries where buildings are mostly not designed for earthquake resistance. A new understanding has come out of amplification of low as well as high frequencies over a deep basin like that of Kathmandu. The knowledge of very high acceleration recorded for low frequencies, not hitherto considered would be useful for designing sky scrapers world-wide. This chapter introduces the contents of different chapters of the book.
