Home Ministry through the National Disaster Management Authority and the Indian National Centre for Ocean Information Services will conduct a multi-State mega mock exercise on tsunami preparedness on Friday. <br/>The exercise will be simultaneously conducted in 31 coastal districts across four States – West Bengal, Odisha, Andhra Pradesh and Tamil Nadu – and Union Territory Puducherry along the entire East Coast. <br/><br/>Participants from 11 Pacific Island countries will observe the entire exercise to take away key lessons and best practices to be adopted while preparing for and responding to a disaster situation. <br/><br/>The exercise is one of the various activities planned on the occasion of the 2nd World Tsunami Awareness Day held on November 5 this year. <br/><br/>India's eastern coast is susceptible to both floods and tsunamis and many coastal districts have conducted similar mock exercises for better preparedness over the years.
