DRRM PLAN
RISK PROFILE AND STATE OF DRRM
I. BASIC TERMINOLOGIES
RISK
It is the combination of the probability of an event and its negative consequences. The
word risk has two distinctive connotations:
Popular usage
The emphasis is usually placed on the concept of chance or possibility, such
as in "the risk of an accident"
Technical settings
The emphasis is usually placed on the consequences, in terms of "potential
losses" for some particular cause, place and period.
Risk is composed of three components, namely:
EXPOSURE
Are the elements present in hazards such as people, property, systems and others
that are subject to potential losses. Measures of exposure can include the number of
people or types of assets in an area.
HAZARD
A dangerous phenomenon, substance, human activity or condition that may cause
loss of life, injury or other health impacts, property damage, loss of livelihoods and
services, social and economic disruption or environmental damage.
VULNERABILTY
The characteristics and circumstances of a community, system or asset that make it
susceptible to the damaging effects of a hazard. There are many aspects of
vulnerability, arising from various physical, social, economic and environmental
factors.
Vulnerability and Hazards are not dangerous, if taken separately. But if they come
together, they become a risk. These two must be simultaneously present in the same
location to give rise to risk which then becomes a disaster if the event actually occurs.
Thus, risk can be expressed as the product of hazard, vulnerability and exposure or in
other words Risk= Hazard x Exposure x Vulnerability. (UNISDR, 2010)
RISK ASSESSMENT
A methodology to determine the nature and extent of risk by analyzing potential
hazards and evaluating existing conditions of vulnerability that together could
potentially harm exposed people, property, services, livelihoods and the environment
on which they depend. This includes a review of technical characteristics of hazards
such as their location, intensity, frequency and probability. (UNISDR, 2010)
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
DISASTER
A serious disruption of the functioning of a community or a society involving
widespread human, material, economic or environmental losses and impacts which
exceeds the ability of the affected community or society to cope using its own
resources.
It is a result of a combination of:
1. Exposure to Hazard
2. Conditions of vulnerability that are present
3. Insufficient capacity or measures to reduce or cope with the potential negative
consequences
DISASTER RISK
The potential losses, in lives, health status, livelihoods, assets and services which
could occur to a particular community or a society over some specified future time
period. It reflects the concept of disasters as outcome of continuously present
conditions of risk.
DISASTER RISK ASSESSMENT
The following are the ideal processes prescribed and tested by NEDA-UNDP-Aus Aid,
which are:
1. Hazard Characterization
Assessment of susceptibility to natural hazards affecting the planning area based
on past disaster events and current observations, to determine if the same pattern of
susceptibility will remain over time.
2. Consequence Analysis
Determining or defining the elements at risk from a given hazard and defining
their vulnerability. This helps us to understand what is at risk (exposure) and identify
the root causes of elements at risk and why these can be damaged (vulnerability).
3. Risk Estimation
Involves the assimilation of the results of the hazard assessment and
consequence analysis to derive an overall measure of risk.
4. Risk Evaluation
Guided by the results of risk analysis, decision makers will now have to evaluate
the level of acceptability of risks.
WEATHER
It is what we can feel, and is the subject of weather forecasts in radio and television.
It is the day-to-day state of the atmosphere, meaning the daily temperature, humidity,
rainfall, and wind. It often changes quickly from day to day.
CLIMATE
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
It is the force that drives long-term changes in weather. It therefore determines the
characteristics of a region (seasons, average temperature etc.). It is described by longterm statistics (e.g. average minimum and maximum temperature).
CLIMATE CHANGE
A change of climate which is attributed directly or indirectly to human activity (such as
the emission of greenhouse gases) that alters the composition of the global
atmosphere in addition to natural climate variability observed over comparable time
periods (United Nations Framework Convention on Climate Change).
Climate changes include increases or decreases in
• Average temperature,
• Average rainfall,
• Sea level rise, and
• The frequency and/or severity of extreme weather events such as typhoons
CLIMATE CHANGE ADAPTATION
It refers to adjustments in ecological, social, or economic systems in response to the
effects or impacts of actual or expected climatic stimuli. It refers to changes in
processes, practices, and structures to lessen or avoid potential damages, or to benefit
from opportunities associated with climate change (United Nations Framework
Convention on Climate Change).
CLIMATE CHANGE MITIGATION
It refers to human intervention aimed at reducing the sources of greenhouse gases or
enhancing the sinks of greenhouse gases. “Sink” means any process, activity or
mechanism which removes a greenhouse gas from the atmosphere (United Nations
Framework Convention on Climate Change).
CLIMATE CHANGE PROJECTION AND IMPACTS
The climate of Malabon falls the Modified Corona’s Classification of Philippine
Climates. This is characterized by a relatively dry season from January to April and
wet during the rest of the year.
The rains start from the month of May, reaching its peak in July, August, and
September through November. The annual rainfall from 1961 to 1995 (Table 3-2) is
1,849.3 mm with an average of 113 rainy days per year. This is slightly lower than the
19511970 average of 1,933.7 mm with 143 rainy days per year. This can be explained
by the El Nino phenomenon in the mid-eighties. The mean temperature in Malabon is
27.45C. The average minimum temperature is 23.2C while the average maximum
temperature is 31.7C. The low temperatures are recorded starting from December
through February. The temperatures slowly increase and reach their peak in May
during the summer months. The average temperatures from1961-1995 given above
are slightly higher than the 1951-1970 averages of 26.6C mean, 22.2C minimum, and
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
31.0C maximum temperatures. This indicates the slowly increasing average
temperature of the area through the years.
RAINFALL
The annual mean number of tropical cyclones that passes across the Philippines is
19.6. The landing frequency on Central Luzon, which affects Malabon, counts for 16%
(PAG-ASA data) or at least 3 times per year.
The maximum rainfall recorded at Port Area in recent years is 509 mm in 2 days (403
mm in one day). The height of +138m average mean sea level (AMSL) that occurred
on July 31, 1996 is the highest observed since 1951, as per NAMRIA’s data.
TEMPERATURE
The temperature during the northeast monsoon ranges from 22°c to 33°c or an
average of about 26°c. Temperature of southwest monsoon ranges from 24°c to 33°c
with an average of about 27°c.
To further understand the climate of Malabon, the table below shows the Observed
Baseline and Climate Projection data for Metro Manila based on studies done by
PAGASA.
Table 41. Seasonal temperature increases (in ⁰C) in 2020 and 2050 under medium-range
emission scenario in provinces in NCR
As the table shows, there’s an increase of temperature during the month of March,
April and May, while the lowest temperature occurs during the month of December,
January and February. An increase in temperature can have the following impact to
the city



Water Shortages
Increased energy demands for cooling
Population health impacts (e.g. increased mortality during heat waves)

Table 42. Seasonal rainfall change (in %) in 2020 and 2050 inder medium-range emission scenario in
provinces in NCR
It can be observed in the table, there’s an increase of rainfall during the month of June,
July and August (during Southwest Monsoon) and decreases of rainfall during the
month of December, January and February (during Northeast Monsoon). An Increase
in rainfall can have the following impact to the city
 Increased flooding
 Property Damaged (homes and businesses)
 More favorable breeding grounds for pathogens
 Population health impacts (increased incidences of water-borne diseases like
cholera)

under the medium-range emission scenario for Metro Manila. The climate change data
derived from the tables are the seasonal temperature increase (in ⁰C), the seasonal
rainfall change (in %), and the frequency of extreme events (Port Area data). Based
on the PAGASA data, the table above shows the summary of climate changes
projected and its effect on the seasonal patterns.
II. RISK PROFILE
Majority of barangays in Malabon would experience five (5) types of hazards,
namely flood, storm surges , ground shaking, liquefaction, severe wind, land
subsidence, solid waste and fire but to certain and different extents. Due to its location
and physical conditions, the city is affected by hazards which some of the cities also
experience such as tsunami and storm surges. Barangays Potrero, Acacia and
Tugatog are considered as the safest barangay being on a higher elevation.

A.HYDRO-METEOROLOGICAL HAZARDS
According to the UNISDR (2009), hydro-meteorological hazard is a process or
phenomenon of atmospheric, hydrological or oceanographic nature that may cause
loss of life, injury or other health impacts, property damage, loss of livelihoods and
services, social and economic disruption, or environmental change. Hydrometeorological hazards include floods, coastal storm surges, typhoons,
thunderstorms, hailstorms, tornados, drought, and heatwaves. It can also be a factor
for other hazards such as landslides, epidemics and fires.
FLOOD
Malabon is likely to experience flooding because of its combined topographic
and hydrological characteristics, as well as the meteorological conditions due to
frequent occurrence of extreme weather events such as tropical cyclones and
monsoon rains (Habagat). The area is characteristically a low-lying flat terrain, with
ground elevation in major parts that are below high tide level. These distinct
topographical features render the area to be frequently flooded by high tide, heavy
rain and river overflow. This is a major issue which impedes the city’s economic
growth and development.
Flooded areas during high tide were mostly concentrated on the
south/southwest portion of the city. On the other hand, during heavy rains, the
east/northeast portions of the city are mostly affected by floods. The navigational gate
located along the Malabon-Navotas River has helped alleviate the flooding problem
along these areas thus, affecting only small portions in the north/northeast part of the
city during rain and high tide. However, due to the ill-designed gate which failed to
consider the presence of shipyards, portions of the south/southwest part of the city
become flooded by high tide, when the said navigational gate malfunctions.
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
The Department of Environment and Natural Resources-Mines and
Geosciences Bureau (DENR-MGB) Flood Susceptibility Map was used in the flood
risk assessment process. The MGB map is a composite of both Typhoon Ondoy and
Habagat/southwest monsoon as well as other historical data. After Typhoon Ondoy,
the team from MGB did a rapid assessment to document the pre, during and post
(Ondoy and Habagat) conditions of affected areas. They validated their data through
ground testing and field interviews. The level of susceptibility was separated in four
categories: Low, Moderate, High and Very High.
Prior to Ondoy, the MGB had a flood cycle map, i.e. 2-3 year longer cycle maps.
They adapted it in their validation and discovered that the amount of rainfall released
by Ondoy was not within the scope of their cycle. The extent of flood during Ondoy
was much spread out and beyond the cycles they produced. It is said that Typhoon
Ondoy has an AEP of 50-120 return period and within 6-8 hours released an
approximate of 400mm of rainfall, while Habagat released almost the same amount
but over a span of 3 days.
The existing flood hazard map of Malabon from the DENR-MGB shows that 18 out of
the 21 barangays are highly vulnerable to flooding. The three (3) barangays – Acacia,
Tugatog and Potrero have a moderate to low susceptibility to floods. The map also
illustrates flood occurrences based on the accounts of Malabon residents. Almost all
barangays are susceptible to flood and most of the affected areas are near the rivers
and waterways.
The study conducted by MGB showed that Typhoon Ondoy is considered to be
the worst case scenario that the city of Malabon could experience with flooding. The
MGB has managed to map out the effects of Typhoon Ondoy which reflected the areas
that were affected and the intensity of its effect in a given area.
Based on the MGB Flood Susceptibility Map, all places in Barangays Dampalit,
Longos, Maysilo, Niugan, Panghulo, San Agustin, Santulan, Tinajeros and Tonsuya
have very high and high susceptibility to flooding. The rest of the barangays in the city
have low to moderate susceptibility to floods, making them safer compared to the
previously-mentioned nine (9) barangays.

HISTORICAL FLOOD EVENTS
Based on the data recorded by the MMDA, during the recent extreme weather
conditions, such as Typhoon Ondoy in 2009 and Habagat (moonsoon rains) in 2012,
around 70% of the area was submerged with water. The flood inundation was due to
its ground elevation being below high tide level, its proximity to Manila Bay and the
several large waterways that overflowed. Overflowing of the rivers can be attributed to
the excess of waters from upstream portions, overspilling of the nearby La Mesa Dam,
the impeded flow of water into the Manila Bay and the inadequate height of the river
walls.
The following list enumerates the recent flood events which affected the city:
1. TROPICAL STORM EGAY AND FALCON
Malabon City experienced heavy rain and flood due to tropical storm Egay and
Falcon from June 20-26, 2011. Four barangays were highly affected, with two
people reported as injured.
2. TYPHOON PEDRING
Malabon City experienced heavy rains and flood due to typhoon Pedring from
September 26-28, 2011. Six (6) out of twenty-one (21) barangays were affected
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
by the typhoon. The estimated cost of damage to properties was about Php
30,000,000.00.
3. TYPHOON GENER
In August 1, 2012, Malabon experienced heavy rain and flood due to typhoon
Gener. Twelve (12) out of twenty-one (21) barangays were affected by the
typhoon.
4. MONSOON RAINS (HABAGAT)
From August 6-9, 2012, Malabon experienced heavy rain and flood due to the
monsoon rains. Sixteen (16) out of twenty-one (21) barangays were affected
during this period.
5. TYPHOON GLENDA
Typhoon Rammasun, known in the Philippines as Typhoon Glenda, was one of
the only two Category 5 super typhoons. From July 15 2014 Malabon
experienced heavy rain and flood due to Typhoon. 347 Families/1,497
individuals from 9 out of 21 barangays are affected during this period.
6. TROPICAL STORM MARIO
Tropical Storm Fung-wong, known in the Philippines as Tropical Storm Mario,
was a relatively weak tropical cyclone which affected the northern Philippines,
Taiwan and the Eastern China. From September 20, 2014 Malabon
experienced heavy rain and flood due to Tropical Storm Mario. 805 Families /
3,232 individuals from 11 out of 21 barangays are affected during this period.
7. TYPHOON RUBY
Typhoon Hagupit (ha-gu-PIT, [hɐguˈpit]; Filipino word meaning "to lash" or "to
flog"), known in the Philippines as Typhoon Ruby, was the second most intense
tropical cyclone in 2014. From Decemebr 8-10, 2014 Malabon experienced
heavy rain and flood due to Typhoon Ruby. 727 Families / 3,069 individuals
from 9 out of 21 barangays are affected during this period.
8. MONSOON RAINS (HABAGAT 2018)
From August 12-17, 2018 Brgy Dampalit are exepecienced heavily flooding due
to continues rain and high tide that caused the damage of mega dike in said
Barangay. 178 families / 868 individuals are affected during this period.
9. TYPHOON ULYSSES
Typhoon Vamco, known in the Philippines as Typhoon Ulysses, was a powerful
and deadly Category 4-equivalent typhoon that struck the Philippines and
Vietnam. It also caused the worst flooding in Metro Manila since Ketsana in
2009. From November 12-14 2020 Malabon experienced heavy rain and strong
wind.
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
POPULATION EXPOSURE
Based on the MGB Flood Susceptibility Map, about 52,033 individuals are
located in areas which are very highly susceptible to floods. About 106,655
individuals live in areas with high susceptibility to floods. Barangay Tonsuya has a
very high susceptibility to floods and will have the highest number of individuals
affected. In terms of high susceptibility, many people in Barangay Santulan will be
affected by flood (Table 75)
Map 9. Population Density Map
DISASTER RISK AND VULNERABILITY ASSESSMENT
There are only five (5) barangays that are at low risk when it comes to flooding,
namely Barangays Acacia, Baritan, Bayan-Bayanan, Flores and Tugatog. These
barangays have low severity consequence and an average of 0% to 10% hazard
vulnerability. Meanwhile, eleven (11) barangays are prone to low to high risk flooding,
such as Barangays Catmon, Concepcion, Dampalit, Longos, Maysilo, Niugan,
Panghulo, Potrero, Santulan, Tinajeros and Tonsuya. These areas have low to high
severity consequence at an average of 0%-100% hazard vulnerability. The remaining
five (5) barangays, including Barangays Hulong Duhat, Ibaba, Muzon, Tañong and
San Agustin, are facing low to moderate risk to flooding, with low to moderate severity
consequence and an average of 0% - 75% hazard vulnerability.
Based on the assessment using the MGB Map, the total area affected by
flooding, the corresponding population and affected value of damages cause by a
flood scenario similar to the floods during Ondoy and Habagat are estimated in the
following sections.
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
In terms of residential areas, Barangay Niugan is very highly susceptible to
flood of more than two (2) meters flood depth and six-year like occurrence. The
estimated loss is about PhP259, 739,266, with a 100% exposure in the affected area
of 17.18 hectares. Leakages of river walls, high tide, inadequate drainage capacity,
sudden maintenance problems of existing pumping stations and extreme rainfall are
causes of flooding in this area.
In terms of commercial areas, Barangay Longos is very highly susceptible to
floods of more than two (2) meters flood depth and six-year like occurrence. The
estimated loss is about PhP 41,484,169, with a 46.52% exposure in the affected area
of 2.54 hectares. The reclamation of the Dagat-Dagatan housing area during the
Marcos regime, through Presidential Decree no. 706 on May 19, 1975 (about 315
hectares portion of the Dagat-Dagatan was reclaimed), increase in population due to
urbanization, inadequate capacity of drainage system and extreme rainfall are causes
of flooding in this area.
In terms of industrial areas, Barangay Panghulo is very highly susceptible to
floods of greater than two (2) meters flood depth and six-year like occurrence. An
estimated loss of PhP 137,227,963.50 with a 32.63% exposure in the affected area of
3.69 hectares. The closing down and abandoning of the owner of Artex compound
sometime in 1984 due to labor dispute turned the land into a virtual water basin. The
location of many industries in low lying areas and near in waterways are also causes
of flooding. (See annex for Built-up structure Exposure table)

B. EARTHQUAKE
The Philippine as a whole has a high level of seismicity, faulting and volcanism.
This is primarily attributed to the location of the country, lying within a broad zone of
deformation between the Eurasian and Philippine Sea Plate. The Philippine fault zone
is a major left lateral strike-slip fault that remains offshore east of Manila. - MALI
Eight (8) barangays in Malabon City have the potential to be affected by seismic
movements and these are Barangays Santulan, Acacia, Potrero, Tugatog and portions
of Barangays Panghulo, Maysilo, Tinajeros and Longos.
The total risk or comprehensive Urban Seismic Risk Index (USRI) incorporates
the potential economic, social and environmental consequences of an earthquake with
social fragility and lack of resilience at the community level.
In terms of physical risk, Malabon falls on the degree of medium to low risk,
while in terms of aggravating coefficient, the city falls on the degree of very high risk.
During the past years, Metro Manila has experienced numerous earthquake,
twenty-eight (28) of which were major, but none of them severely affected the city of
Malabon. The city only experienced ground shaking even during the highest recorded
Richter Magnitude in history.

2022-2026
In the occurrence of ground shaking, findings show that there will be about
1,311 fatalities will be in Malabon with approximately a gross amount PhP
3,384,886.00 worth of loss in building damage and an economic loss of PhP
5,932,500.00.
Base on RAP, Barangays Longos and Potrero are extremely vulnerable to
damage loss, economic loss and loss of lives. Table 79 and Maps 19-22 show the
projected risk values due to ground shaking.
Table 47. Projected risk values due to ground shaking
C. SEVERE WIND
There are two kinds of wind in the Philippines, the Amihan and Habagat. The
main indicator of the change between the Amihan and Habagat seasonal pattern is
the change in wind direction. Amihan refers to the season dominated by trade winds
as a cool northeast wind, characterized by moderate temperatures, little or no rainfall,
and prevailing wind from the east. Its pattern begins sometime in September or
October and ends sometime in May or June.
Throughout the rest of the year, the Philippines experiences the west or
MALABON DISASTER RISK REDUCTION AND MANAGEMENT PLAN
2022-2026
southwest wind referred to as Habagat. It is characterized by hot and humid weather,
frequent heavy rainfall, and a prevailing wind from the west.
The downstream area of the Tullahan River is situated in Malabon. As a
consequence, during the onset of Habagat, which caused heavy rainfall, all 21
barangays have been affected by severe winds. The three barangays considered to
be mostly affected in relation to building damage area equivalent are Barangays
Catmon, Tonsuya and Maysilo. Barangays Potrero, Tinajeros and Maysilo were
affected in terms of building damage cost; and Barangays Dampalit, Muzon and
Panghulo were affected in terms of average wind speed (Map 23).

D. LIQUEFACTION
Malabon is found to settle about 3 cm. every year. Liquefaction is a
phenomenon in which the strength and stiffness of a soil is reduced by earthquake
shaking or other rapid loading. Related phenomena have been responsible for
tremendous amounts of damage in historical earthquake around the world.
Liquefaction is also a process by which water saturated sediments temporarily loses
strength and acts as a fluid. It usually occurs when vibrations or water pressure within
a mass of soil cause the particles to lose contact with one another. As a result, the soil
behaves like a liquid, has an inability to support weight and can flow down very gentle
slopes. This condition is usually temporary and is most often caused by an earthquake
vibrating water-saturated fill or unconsolidated soil.
Liquefaction most often occur when these three conditions are met: loose,
granular sediments or fill; saturation by ground water and; strong shaking. Malabon is
affected by this phenomenon.
Table shows the barangays that are susceptible to liquefaction.

Motivational/Attitudinal
Many residents are members of
at least one organization
Existing organizations and
institutions are skilled/trained
Many organizations and
institutions are also catering to
the less-fortunate members of the
community
There is diversity among the
advocacies of the organizations;
Vulnerable sectors are also wellrepresented
Wide scope of networks of
several organizations, as they are
also found and operational in
other barangays
Cooperatives and insurance
companies serve as options for
livelihood/finance sources of
some community members
Known respected leaders
Peaceful elections and no conflict
between political parties
Approachable and accessible
members and staff of the DRRM
Council
Active and existing MCDRRMC
Thinks of alternative ways to meet their
daily needs
Doesn’t depend on others
Prepares for the coming disaster
believes in God; they get strength in
overcoming their situation from their
belief

Limited funding
and resources of
organizations

Lack of
monitoring and
coordination
between
organizations

Need for trainings
and awarenessraising programs
for BDRRMC
members
Need for
ground/sitio
leaders

individualistic take on
finding ways to meet
their daily needs
There are people who
don’t want to evacuate
because they believe
that their situation in the
evacuation center is not
different when they are
at home and they can
guard their houses
against burglars if they
stay
There are those who
believe that there is no
hope for them to
succeed in life
The cooperation and
motivation of the
members of the
organization weakened

exclusive for the people in the same
religion
The evacuation center is relatively new:
 New facilities (rooms, CR)
 There are assigned areas for
cooking, washing, for vulnerable
groups (PWDS, PLW, senior,
etc.)
In cases of emergency,
everyone wants to be
the first to be rescued or
get relief goods
The view on the word
“evacuees” and
“evacuation center/s”
There are parents who
have low
involvement/participation
in the school activities of
their children
Some of the evacuees
don’t follow the ECs
