disseminated four days before Phailin struck
land, allowed for the evacuation of approxi-
mately 400,000 people on or by 11 October
(Senapati

1.2 million people were evacuated (GoO

resulting in the largest evacuation operation in
India in 23 years (IFRC
2013
). Early warning
also allowed for the relocation of more than
30,000 animals. A total of 21 lives were lost as a
result of the cyclone and an additional 23 lives

a consequence of rise in phyto-
