Over the last fifty years, disasters caused by landslides and floods have become ten times more frequent, despite landslides being significantly underreported in global databases. Worldwide, 4500 people are killed on average each year already, and landslide risk is set to escalate even further in the future under two increasing trends—climate change and urbanization. More than 80% of fatal landslides occur in the tropics, mainly triggered by heavy rainfall during cyclones and monsoons.
