matches,fresh water,and first aid kit)and an evacuation strategy.
• Prepare important records and keep them within reach.
• Listen to your local radionews station for an infofrmation about the flood.
• Protect valuables by moving them to high and elevated places.
• Turn off the main switch for electricty,water and gas tank.Take your cellular
phones with you in case you need to make an emergency call.

6. • Severe Storm
Storm is the atmospheric disturbance
characterized by strong winds together with
rain,snow,or other forms of precipitation.It is
primarily caused by the wind system affected by the
rotation of the earth.Severe storm causes flash

flooded streams.

8. • Tsunami
It is a large ocean wave due to underwater earthquakeor
volcanic wave.It is usually caused by any large ,impulsive
displacement of the sea leve.Earthquake and landslide may
also trigger atsunami.
Some of the devastating effetcs of tsunami are loss of life
and destruction of properties.The force of wave leads to
coastal erosion that wears away coastal land and beaches,
and destroys buildings,bridges,cars,trees,and electical wires.

9. 1. Watch out for warning signs of a tsunami.
2. Look for a higher place where you can seek safety.Avoid
low-lying areas such as sea shores and open fit fields.
3.After a tsunami,you must wait fofr some time before
heading outside to make sure that there are no more
approaching waves following the first wave.

10. • Earthquake
An earthquake is a sudden shaking or rolling of the earth’s
surface.It occurs due to plate movement or volcanic activity.Human
activities such as unclear explosion,mining,and quarrying can also
trigger an earthquake.The intensity of earthquake can be measured
by an seismograph,a device used to detect and measure seismic
waves generated by a volcano.The point of origin of movement is
called focus or hypocenter while the point above the focus is known
as epicenter.The most frightening about an earthquake that it
happens without a warning.IT would be very hard to protect people
and property from an earthquake destruction.

11. • Stay away from the windowa,mirrors,and other objects that may fall like a wall
decorations,flowers vases,books,and cabintes.

• Prepare for a series of after shocks following the initial earthquake.
• If you are in an earthquake prone area,be particular in fixing ffurnitures and
appliances.

12. • Volcanic Eruption
Volcanoes are landform that are shaped by rising
of molten rocls inside the earth’s
surface.TRememdous heat and pressure cause the
volcano to expelmolten rocks.When a volcano
erupts,molten rocks beneath the earth’s surface
,known as magma,rise due to temperature and
pressur.Magma contains crystals,fragments of rocks
and glasses.
