1. Tornado
Tornadoes are the result of the clash of warm and cool air. Almost all tornadoes occur in areas where a cool air mass moving in undercuts an existing warm air mass in place.
2. Tsunami
A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea.
3. Volcanic eruption
Volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust.
All volcanic activity comes down to the same basic principle, eruptions are the result of magma from beneath the Earth being pushed up to the surface where it erupts as lava, ash and rock.
4. Sinkhole
Sinkholes are formed by underground soil erosion . Most of the time sinkholes aren’t detected until they literally sink and make damages or even injuries to the property.
5. Earthquake
It’s the shaking of the earth produced when rock which are locked together, fail and slip, releasing the pressure that made them fail.
Most of the source of this pressure comes from tectonic plates colliding with each other, slowly over many years.
6. Landslide
A landslide usually occurs along a steep hillside where a tremendous amount of rain occurred. The weight of saturated earth, increased by gravity and the steepness of the mountain or hillside; causes the mud to slide. The destruction of homes in its wake can be tremendous.
