hazards caused by the earth by tectonic/ geological events such as eathquakes, volcanic eruptions, landslides and tsunamis
3 of 12

hazards formed by hydrological and atmosheric processes such as floods, storms,tornadoes and drought
4 of 12

7 of 12
vulnerability
shaped by state of human development, poverty levels, living in fragile enviroments and an inability to cope with hazards. vulnerability is shown in Dregg's model
8 of 12
techno hazards
human made hazards such as the chernobyl powere station disaster of 1986
9 of 12
Na-tech hazards
hazards caused by a combination of human and natural hazards such as the Fukushima power plant disater in 2011
10 of 12
chronic hazards
hazards which are not one off events but are ongoing such as climate change and teh destruction of mangroves and the rainforest
