Natural Disaster Drought is a serious phenomenon which results in widespread impact on livelihoods and causes severe problems. Drought: About 50 million people died. Affected 60 million people. Destroyed 60 million hectares of crops. 60 million hectares are prone to droughts. Flood: Floods cause widespread destruction of crops and infrastructure. 75% of all natural disasters are floods. In recent years, floods have caused severe damage in many parts of the world. First Aid Services Protect people from water-borne diseases Protect food and water from contamination Ensure access to clean and safe water Ensure access to essential and necessities Ensure water level is increasing Moving to safe places if the water level is increasing often Tsunami Tsunami means "harbor wave" in Japanese. It is a series of waves in a body of water caused by an underwater disturbance such as an earthquake, volcanic eruption, landslide, or meteorite impact. The wave travels across the ocean and as it approaches the land, the wave slows down and grows in height. Waves can travel at speeds of 300–800 km/h. As it approaches the land, the water becomes compressed (sometimes up to 10 times the height of 30 meters) and the weight of the water is sufficient to cause devastating flooding. The destruction caused by tsunamis is considerable. The December 2004 tsunami killed 310,000 people, the deadliest tsunami in recorded history. Earthquake No earthquake is the same. It causes violent movement of the earth's surface from the release of energy in the earth's crust. Earthquakes occur when masses of rock within the earth shift or break, releasing energy in the form of seismic waves. This energy is transmitted to the surface of the earth by earthquake waves. Earthquake These seismic waves are called "P" waves (Primary waves) and "S" waves (Secondary waves). Scientists who study earthquakes are called seismologists. First Aid Ask all the people cautiously inside the building to come out in open space. Focus on the necessities to still possible. Known contacts in the area. Establish telephone to save human lives. Safety then protects non-living objects. Protect the children from being alone.
