Floods in Kerala in 2018 were caused by heavy monsoon rainfall that submerged land and displaced thousands of people. Over 483 people died when dams were opened and landslides occurred, flooding villages and destroying homes and infrastructure. The floods impacted over 1.2 million people who sought shelter in relief camps with disrupted basic services like water, electricity and transportations.
