Disaster Mitigation and Management

OBJECTIVES:

• To create an awareness on the various types of disasters and to expose the students about the measures, its effect against built structures, and hazard assessment procedure in India.
• To impart knowledge on the methods of mitigating various hazards such that their impact on communities is reduced.
