Identify the Natural Hazards of geophysical origin among the following : 

(A) Wildfires 

(B) Floods

(C) Subsidence

(D) Tsunami 

(E) Heatwave 

Choose the correct answer from the options given below : 

Natural hazards are described as natural events that have the potential to have an influence on human society and the environment.

Key Points

• Geophysical catastrophes are natural disasters caused by tectonic and seismic activity beneath the surface of the Earth.
• Most geophysical catastrophes have a level of unpredictability that makes it difficult to accurately predict when one will occur. 
• Some examples of  Natural hazards of geophysical origin are floods, subsidence, tsunami, volcano, earthquake, hurricanes and tropical storms tornadoes etc. 
• Floods can happen in a matter of minutes or over a lengthy period of time, lasting days, weeks, or even months. 
• A tsunami is a catastrophic ocean wave that is typically triggered by an undersea earthquake, an underwater or coastal landslide, or a volcanic eruption. 

Therefore, floods, subsidence and tsunamis are identified as the natural hazards of geophysical origin. 

Additional Information

• In contrast to natural disasters caused by natural risks, man-made disasters involve human intent, neglect, or error involving a failure of a man-made system.
• Such man-made disasters are crime, arson, civil disorder, terrorism, war, etc.
