2. There are different types of hazard: Hydro Meteorological Hazards Caused by climate processes, these include droughts, floods, tropical cyclones/storms Geophysical Hazards Caused by land processes, these include earthquakes, volcanic eruptions and landslides.

4. THE DISASTER RISK EQUATION Hazard [H] X Vulnerability [V] Risk [R] = Capacity to cope [C] The risk of a disaster increases as the frequency or severity of hazards increases, people’s vulnerability increases and people’s capacity to cope (ability to cope with the consequences) is decreased.
5. Another reason why it may seem that the number of disasters has increased is because of greater media coverage – more disasters are reported than in the past, so it seems as if more are actually happening Hydro meteorological hazards are becoming more frequent Its thought that the increase in hydro meteorological hazards is due to the increasing effects of global warming - which is thought to be largely due to human activity The number of geophysical hazards hasn’t changed much
6. There are a number of factors why disasters are increasing:
7.
8. prevention - natural hazards can’t be stopped, but they can be prevented from becoming disasters, e.g. By using sand bags to protect against the effects of flooding
