Seismic Building Codes in the Himalaya Region. Questions & Answers Related to the 2015 Nepal Earthquake. (May 2016). 37 pages. 3.3 MB 

Abstract.  Where do these earthquakes occur?  What is the purpose of the seismic code and the relation with the building code?  What are the differences between seismic codes of other countries?  What variables exist in a seismic code?  What technical and/or administrative measurements need to be taken to make the code effective?  How does this information translate to a country as Nepal ?
