CAUSES OF FLOOD

2010 Pakistan Flood

The 2010 Pakistan floods began in late July 2010 following heavy monsoon rains in the Khyber PakhtunkhwaSindhPunjab and Balochistan regions of Pakistan and affected the Indus River basin. At one point, approximately one-fifth of Pakistan's total land area was underwater. According to Pakistani government data the floods directly affected about 20 million people, mostly by destruction of property, livelihood and infrastructure, with a death toll of close to 2,000. The number of individuals affected by the flooding exceeds the combined total of individuals affected by the 2004 Indian Ocean tsunamithe 2005 Kashmir earthquake and the 2010 Haiti earthquake.
