Unit 1.3 Global Hazards Using the graphs from Unit 1.3, I am able to outline the trends in global disasters. The number of natural disasters reported has increased over the last 30 years. In 1930, about 25 natural disasters were reported. In 1970, there was a sharp increase and this carried on until 1995. Overall, numbers have increased over the last 50 years, however, by 2000, the trend line started to become level. One reason for an increase of natural disasters could be because of much stronger hurricanes due to global warming, or because of there has been an increase in media coverage. There has actually been an increase in hydro metrological hazards (floods and windstorms) for the last 20 years, however, geo-physical hazards have remained the more or less the same. The total number of people reported killed by natural disasters has decreased since 1960, but there was a slight rise since 2003, however, between 1924 and 1936, the number of people reported dead was at its highest (0.8 millions of people). On the other hand, the total number of people reported affected by natural disasters has increased from 0, to 250 millions over the last 50 years. This shows that the population is growing, and more people are choosing to live in hazardous areas, thus concluding that more people will be affected. The number of disasters has increased but the numbers of deaths has fallen. This could be because of global warming, which has increased the number of hurricanes, tornadoes and other tragedies (hydro metrological hazards). On the other hand, the number of deaths has fallen because of Predictions, (which are 90% accurate, and help give a better understating of the disaster unfolding) Precautions, (meaning people don’t take any chances, and evacuate their homes) and Preparedness (working as community to prepare for any disaster). The amount of economic damage has
