Effects:
← 2379 people died.
← Destruction of communication network meant it was impossible to deliver food and medical supplies, leading to further deaths. ← 25 million made homeless, due to flood waters destroying homes. ← Floods covered over 60% of the land, destroying the year’s crops; quarter of the rice crop was destroyed. ← Out breaks of water born diseases such as cholera, diarrhea, lasted for several months as sewage polluted the waterways.
