natural disaster definition

Natural disasters can be defined as a group of destructive events that leave negative effects comparable to the damages of war on the environment and humans, and are beyond human control; It cannot control or prevent it from happening and it is either atmospheric, or geological, or hydraulic; Such as earthquakes, volcanoes, droughts, hurricanes, and others, which will be discussed in more detail later.[1]

How to deal with natural disasters

Natural disasters are inevitable and humans cannot prevent them from happening, but in return, attempts can be made to control them, and to reduce as much as possible their negative effects on society through the following:[2]

  • Strengthening human responsibility to stop practices harmful to the environment that lead to the deterioration of the global ecosystem, and to take into account all disasters that may occur by developing backup plans to act in the event of any possible natural disaster to get out of it with the least possible losses, regardless of the devastating consequences for infrastructure and structural As for the natural disaster, there are great losses to human lives as well, so here comes the most important role of the precautionary plans developed to deal with these losses effectively and quickly to reduce them and avoid the worst.
  • direct concern in the aftermath of a disaster; The physically affected and injured must be controlled to prevent the spread of infection.
  • Develop scientific research related to forecasting techniques for weather conditions, and enhance monitoring related to volcanoes, earthquakes, etc., to know their impact on the available natural resources and how to avoid them.[3]
  • application of advanced technology; such as improving communications, to ensure that warnings are disseminated as widely as possible.[3]

Examples of natural disasters

Here are some of the most common examples of natural disasters:


A volcano can be defined as a crater in the Earth’s crust that allows molten rock, gases, and debris to rise to the surface of the Earth. An eruption may include lava and other debris that can flow at up to 161 km/h. Volcanoes are considered one of the most dangerous natural disasters as they can cause serious health problems.[4]Among the most important tips to maintain safety in the event of an erupting volcano in the area are:[5]

  • Evacuation as determined by the responsible authorities to stay away from lava and flying debris.
  • Keep away from rivers and low-lying areas.
  • Wear long-sleeved shirts and long pants before leaving the house, use safety glasses and avoid contact lenses.


An earthquake can be defined as a state of sudden vibrations of the Earth’s surface caused by the passage of seismic waves through the rocks in the earth’s interior. Earthquakes typically occur along geological faults and narrow areas where rocks move dependently on each other.[6]Here are the most important tips to keep in mind when earthquakes occur:[7]

  • Learn how to close gas pipes and water valves.
  • Hide under a table or stand in an empty space in the house to avoid tumbling when the vibrations start.
  • Stay away from buildings, electricity poles, and trees, and bend to the ground when outside.


A tornado can be defined as a vertical funnel of winds that rotate at a very fast speed that may exceed 400 km / h. It can cross a path 1.6 km wide and 80 km long. Most tornadoes are formed during thunderstorms, often accompanied by hail. Violent hurricanes constitute only 2% of all hurricanes, but they cause about 70% of all hurricane deaths, and may last an hour or more, and it is worth noting that violent hurricanes occur all over the world, but the United States of America is one of the countries that most This type of hurricane is concentrated in it at a rate of 1,000 hurricanes every year.[8]Among the most important tips that must be taken into account when a hurricane occurs are the following:[9]

  • Prepare for the hurricane to come by preparing all the important tools for an emergency including: water, food, a first aid kit, and a fully filled gas tank.
  • Move away and resort to shelters in basements or on the ground floors when the hurricane approaches.
  • Stay away from cars or mobile homes as they do not provide any kind of protection against a hurricane.


Flooding is the most common and widespread natural disaster related to the weather, and a flood can be defined as a rise in the water level on a usually dry land, and it commonly occurs by intense heavy rain, when snow melts rapidly, or when water dams burst, Floods can be several centimeters above the ground, or they can be so high that they completely cover a house to the surface.[10]

Flash floods are the most dangerous type of flood; It combines the destructive power of a flood with extreme speed, and is unpredictable, and this flood occurs when excess water fills dry riverbeds, or riverbeds at the same time as flowing streams and rivers, causing a rapid rise in the water level within a short period of time ,[10]Among the most important tips that must be taken in case of floods are the following:[11]

  • Immediate evacuation to higher areas in the event of a warning issued by the authorities responsible for a sudden flood.
  • Stay away as much as possible from sources of electricity and do not touch them in cases of wetness or standing in water.
  • not walk through moving water; The moving water level of 15 cm may only cause a fall.
  • Avoid driving cars during floods, and in the event of being inside them, they must be evacuated and go to the highest possible point if it is safe to do so.
