Earthquake Engineering- A Comprehensive Guide

Vinod Gopinath

Earthquake Engineering though not a mainstream engineering branch, is a widely researched topic now. Though all of us wouldn’t have experienced an earthquake most of us must have seen news and videos about the tremendous loss it causes. Looks scary, right? That’s exactly what makes Earthquake Engineering a subject of immense possibilities and research.
