2. Tsunami
Istilah "tsunami" berasal
dari bahasa Jepang yang berarti
pelabuhan ("tsu") dan gelombang
("nami"). Tsunami adalah
serangkaian gelombang yang
dihasilkan ketika air di danau atau
laut dengan cepat mengungsi dalam
skala besar.
Tsunami dapat dihasilkan
ketika dasar laut tiba-tiba
deformasi dan vertikal
menggantikan air di atasnya. Seperti
pergerakan vertikal besar kerak
bumi dapat terjadi di batas lempeng
General Statement :
The term of “tsunami”
comes from the Japanese which
means harbour ("tsu") and wave
("nami"). A tsunami is a series of
waves generated when water in a
lake or a sea is rapidly displaced on
a massive scale.
Squenced of explanation :
A tsunami can be
generated when the sea floor
abruptly deforms and vertically
displaces the overlying water.
Such large vertical movements of
the earth's crust can occur at
plate boundaries.

3. Tsunami
• Subduction of
earthquakes are
particularly effective in
generating tsunami, and
occur where denser
oceanic plates slip under
continental plates.
• As the displaced water
mass moves under the
influence of gravity to
regain its equilibrium, it
radiates across the ocean
like ripples on a pond.
• Subduksi gempa sangat
efektif dalam
menghasilkan tsunami, dan
terjadi di mana lempeng
samudera lebih padat
menyelinap di bawah
lempeng benua.
• Sebagai massa air yang
dipindahkan bergerak di
bawah pengaruh gravitasi
untuk mendapatkan
kembali keseimbangannya,
ia memancarkan seberang
lautan seperti riak di
kolam.

4. Tsunami
• Closing :
• Tsunami always bring
great damage. Most of
the damage is caused
by the huge mass of
water behind the
initial wave front, as
the height of the sea
keeps rising fast and
floods powerfully into
the coastal area.
• Tsunami selalu
membawa kerusakan
besar. Sebagian besar
kerusakan disebabkan
oleh massa besar air di
balik gelombang depan
awal, karena
ketinggian laut terus
meningkat cepat dan
kuat banjir ke daerah
pesisir

12. What the last Paragraph about
• Great damage result of
the tsunami.
• Kerusakan besar
akibat dari tsunami

13. The tense mainly used in the text
• Use Simple Present Tense
S + Vs/es + O
A tsunami is a series of waves generated when
water in a lake or a sea is rapidly displaced on a
massive scale
• Use Passive Voice
O + tobe + (is am are) + V3 + by + S
A tsunami will be generated when the seafloor
abruptly deforms and vertically displaces the
overlying water.

14. Words showing cause and effect
• Tsunami always bring
great damage. Most of
the damage is caused
by the huge mass of
water behind the
initial wave front, as
