Answer:
Natural Disaster
A natural disaster is a major adverse event resulting from natural processes of the Earth; examples are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic processes. A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover and also on the infrastructure available.
Types of Natural Disasters:
- Tornadoes and Severe Storms
- Hurricanes and Tropical Storms
- Floods
- Wildfires
- Earthquakes
- Drought
Causes of Natural Disasters:
Earthquakes are one of the most devastating and frightening natural disasters a person can experience. They happen without warning in areas all around the world. Earthquakes can cause major damage and fatalities in populated areas, but the earthquake itself is not always to blame. Other natural disasters can be caused by earthquakes and these can be equally, and sometimes more, destructive.
Earthquakes may trigger volcanic eruptions. For example, in 1975, a massive earthquake hit Hawaii and a few hours later, the summit caldera in Kilauea erupted. Most earthquakes occur on or near the edges of tectonic plates. Similarly, a volcano is the result of the interaction of these plates. Scientists believe that seismic waves coming from earthquakes cause disturbances in the molten rock beneath volcanoes, making them active.
