5. Earthquakes are caused by
the sudden movement of
tectonic plates in the Earth's
crust. . They can result in
ground shaking, ground
displacement, landslides,
liquefaction, and tsunamis.
The severity of earthquakes is
measured using Richter Scale,
which ranges from 1 to 10.

7. LANDSLIDES
Landslides occur when soil and
rock materials slide down a slope
due to the force of gravity.
Landslides can be triggered by
natural events such as heavy rain,
earthquakes, and volcanic
eruptions, as well as by human
activities such as deforestation and
construction. Landslides can cause
damage to infrastructure and result
in loss of life

9. Tsunamis are large ocean
waves that are triggered by
seismic events such as
earthquakes, volcanic
eruptions, or landslides.
They can cause widespread
destruction in coastal areas,
leading to loss of life and damage
to infrastructure

11. Sinkholes are depressions or
cavities in the ground that occur
when soil or rock collapses. They
can be caused by natural
processes such as erosion, or by
human activities such as mining
and groundwater pumping.
Sinkholes can result in damage to
infrastructure and loss of life.

13. ROCKFALLS
Rockfalls occur when rocks
detach from a slope and fall to
the ground. They can be
triggered by natural events
such as earthquakes and
weathering, or by human
activities such as mining and
construction. Rockfalls can
cause damage to infrastructure
and result in loss of life

15. In conclusion, geological hazards can have devastating
impacts on human life and infrastructure. Understanding the
different types of geological hazards and their characteristics
is crucial in developing mitigation strategies and preparing for
potential disasters.
