the Atlantic Ocean and
northeastern Pacific Ocean, a
typhoon occurs in the
northwestern Pacific Ocean, and
a cyclone occurs in the south
Pacific or Indian Ocean.
14. What is a Storm Surge?
a rising of the sea as a result
of atmospheric pressure
changes and wind associated
with a storm.

of the sea along a coast
caused by the onshore winds
of a severe cyclone or storm.

16. The Risk of Earthquake, Volcanic
Eruptions, Tsunami in the
Philippines
• The Philippines is situated along a highly
seismic area lying along the Pacific Ring of Fire
• Risk report published by United Nations
University and the Institute of Environment and
Human Security, looking into 4 components of
risk (exposure, susceptibility, coping and
adaptive capacities, PHILIPPINES IS THE
THIRD MOST DISASTER RISK COUNTRY
WORLDWIDE

17. Pacific Ring of Fire
The Pacific Ring of Fire has more
exploding volcanoes and great
earthquakes than any other place
on Earth. This 25,000 mile ribbon
of land and water is home to 75% of
the world's active and dormant
volcanoes. Earthquakes are
common in the Ring of Fire where
80% of the great earthquakes on
our planet occur.
19. Earthquake
An Earthquake is a sudden
tremor or movement of the
earth's crust, which
originates naturally at or
below the surface. Usually
caused by tectonic or volcanic
activity.
28. Dashed line: Fault trace is approximate
Fault whose precise location on the ground cannot be delineated
because erosion, human activity, etc. have erased their traces.
Dotted line: Fault trace is concealed
Fault trace is concealed on the ground by
recent sediment deposits. Usually across
rivers and river deposits, landslide deposits.

30. The West Valley Fault has the potential of
generating a devastating magnitude 7.2
earthquake in Metro Manila and nearby
provinces.
Phivolcs director Renato Solidum warned the
West Valley Fault, which traverses parts of Metro
Manila and adjoining provinces of Bulacan,
Laguna, Rizal and Cavite, is ripe for a possible
strong earthquake.
Solidum said “It can happen within our lifetime,”.
He also said that the West Valley Fault moves
every 400 to 600 years. The last time it moved, he
said, was in 1658 or 359 years ago.
