Earthquakes were found to be the largest hazard, with the number of people potentially affected jumping from 1.4 billion in 1975 to 2.7 billion in 2015. Now, they say one in three people is exposed to the risk of earthquakes.
In the last few decades, the risk has dramatically increased; the number of people living in seismic areas, for example, has increased by 93 percent in just 40 years.
The findings, compiled in the Atlas of the Human Planet 2017, reveal the global exposure to natural disasters has doubled since 1975, largely as a result of population growth and development.
