2015 Assam floods were floods in the Indian state of Assam which were triggered by heavy rainfall at the end of August in neighbouring Arunachal Pradesh state through Brahmaputra river and its tributaries. The floods are reported to have caused the deaths of 42 people and numerous landslides, road blockages and affected 1.65 million people in 21 districts. Flooding affected 2,100 villages and destroyed standing crops across an area of 180,000 hectares (440,000 acres). In the Dhubri district alone, more than 400 villages are now almost impossible to reach making it difficult to send aid to the suffering civilians.
However, this is not the first time the Assam state has experienced destructive flooding; the region is possibly India's most flood-prone state and has experienced at least 12 major floods since 1950. Although always prone to floods, the frequency of disastrous floods was increased in the area after the 1950 Assam-Tibet earthquake, also referred to as the "1950 Great Earthquake".
