Learning Objectives
❑Using hazard maps, identify areas prone
to hazards brought about by earthquake,
volcanic eruptions, and landslides.
❑ Identifying human activities that speed
up or trigger landslides
The Philippines ranks among
the world’s most disasterprone countries. It is highly
prone to natural disasters,
particularly typhoons, floods,
landslides,
volcanic
eruptions, earthquakes, and
tsunamis, lying as it does in
the typhoon belt, in the
active volcanic region known
as the “Pacific Ring of Fire,”
and
in
the
geologically
unstable region between the
Pacific and Eurasian tectonic
plates.
Eight of the 10 most
disaster-prone cities
in the world are in
the Philippines.
•Tuguegarao in Cagayan (2nd)
•Lucena in Quezon Province
(3rd)
•Metro Manila (4th)
•City of San Fernando in
Pampanga (5th)
•Cabanatuan in Nueva Ecija
(6th)
•Batangas (7th)
•San Carlos – (no province
specified in the report) (9th)
•Naga in Camarines Sur (10th)
PARTS OF THE HAZARD MAP
❑ TITLE OF THE MAP- it gives the information
such as area of concern and the particular
hazard that it represents..
❑ LEGENDS AND SYMBOLS-it includes broken line
that may represent roads/ highways, or solid
lines that may represent a border or
boundary of a particular places. It may use
different colors to indicate some important
information.
❑ NORTH ARROW- it gives the user of the map a
sense of direction of the place.
❑ SCALE OF THE MAP-it is the ratio between the
map to the actual area or places it
represents.
LESSON 2
LANDSLIDES-A mass
movement of rock, soil,
and debris down to a
slope due to gravity. It is
a natural process that
occurs commonly in
steep slopes.
LESSON 2
Massive Landslide in Toledo City, Cebu
On 21 December 2020, in the
aftermath of tropical storm
Vicky. A very large landslide
occurred at the Carmen copper
mine, also known as the Toledo
Copper Mine, at Don Andres
Soriano (Lutopan), Toledo City,
Cebu in the Philippines. This
landslide is known to have
killed four miners, while six
more remain missing, with no
prospect of survivors.
HUMAN ACTIVITIES: TRIGERRING UP THE LANDSLIDES
1. MINING-the extraction of
valuable minerals or other
geological materials from the
earth, usually from an
orebody, lode, vein, seam,
reef or placer deposit.
4 MAIN MINING METHODS
a. Underground Hard Rock Mining
b. Open-pit mining
c. Placer mining
d. In-situ leaching (ISL
HUMAN ACTIVITIES: TRIGERRING UP THE LANDSLIDES
2. QUARRYING-the
breaking free and removal
of rock fragments by shock
pressures from breaking
waves, water hammer, and
the compression of air in
rock joints.
HUMAN ACTIVITIES: TRIGERRING UP THE LANDSLIDES
3. EXCAVATION- the act
or process of digging,
especially when something
specific is being removed
from the ground
