Millions of people are affected by both natural and man-made disasters. They involve explosions, earthquakes, floods, hurricanes, tornados, or fires. Disasters can pose threat to life or long term impacting injuries. There is also a threat to the property, possessions and community. There are various types of natural hazards taking place. They include:-

• Geological hazards- They occur because of volcanic activity. These events include earthquakes, volcanic eruptions, and landslides.
• Meteorological hazards - They occur as a result of processes in the atmosphere. Meteorological hazards include extreme temperatures, hurricanes, tornadoes, droughts, and severe storms.
• Hydrological hazards are hazards involving water processes. Examples include floods, droughts, and tsunamis.
• Biological hazards occur due to the biological processes of the earth and primarily involve the spread of diseases and pests. Epidemics, pandemics, and insect swarms all fall into the biological hazards category.

Owing to different types of hazards, there are various types of effects due to the occuring of these hazards. These effects are chronological. They happen one after the other. They are:-

1. Primary Effects:- These are the direct impacts of the disaster occuring immediately after the disaster has happened. They include damage of land and property. Broken trees, collapsed builldings, damaged electric lines, water lines etc. The another important primary effect of the disaster is that it can surge storms and tornadoes.
2. Secondary effects:- These are the effects of the primary effects. They can be called as intermediate term effects of the disaster. Due to the damage to the land and property, humans routine life is disturbed. There are power cuts, forest fires, crop damage.
3. Tertiary effects:- These are the long term effects of both primary and secondary effects of the disaster. These include crop failure, loss of crop yield, migration of community, changes in the flow of river, soil damage, waterlogging, loss of heavy funds to recover the impacted areas, decrease of production capacity of equipments etc.
