Disaster Readiness

and Risk Reduction

Quarter 1 – Module 14:
Interpret Earthquake
Hazard Map

CO_Q1_DRRR SHS
Module 14
 What I Need to Know

In this module, the learner will be able to identify different earthquake hazards at
home. This will further teach the learner how to sketch an earthquake map and be
able to interpret it according to its degree of damage in order to make the whole
family safe and free from harm during earthquake. To lessen if not to avoid danger
during disasters, the learner is expected to become a keen observant by knowing how
to identify different earthquake hazards present at home. Aside from having a skill
in identifying earthquake hazards at home, this module will also help the learner and
other family members to propose appropriate actions for disaster readiness.

In this module, the learner will be able to determine what is earthquake hazard map
and its crucial role upon pertaining to the assessment of risk that a particular place
could take. This will further teach the learner on how to manage or raise peoples’
anticipation and readiness regarding the hazard and risk that the place may take.
To lessen the counts of possible casualties, the learner is expected to become
knowledgeable of interpreting earthquake hazard maps and resilient by giving
insights and ideas where to go and find a safe and secured facilities and shelters in
doing the evacuation procedures to reduce the dangers of hazards that supposedly
present at home and in the community. This module will also help the learner to
identify, create earthquake hazard map and become well-familiarize of preventive
measures such as evacuation procedures and decision making in terms of location
where to evacuate in case of hazard and risk occurrence.

The module is consist one lesson only.

• Interpret Earthquake Hazard Maps.

After going through this module, you are expected to:

1. identify different earthquake hazards at home;
2. appreciate a hazard map by creating one within the vicinity
of the house; and
3. interpret an earthquake hazard map according to the degree
of damage.

This lesson explains the importance of having a knowledge of interpreting an
earthquake hazard map which is very essential not only in the family but also in the
community. It will also help the learner on how to create a family hazard map which
will they use during evacuation.

What is It

What is a Hazard Map?

A hazard map is a map that highlights areas that are affected by or are vulnerable
to a particular hazard. They are typically created for natural hazards, such
as earthquakes, volcanoes, landslides, flooding and tsunamis. Hazard maps help
prevent serious damage and deaths.

5 CO_Q1_DRRR SHS
Module 14
(“Hazard Map.” 2020. Wikipedia. October 29, 2020.
https://en.wikipedia.org/wiki/Hazard_map.)

Hazard maps provide important information to help people understand the risks
of natural hazards and to help mitigate disasters. Hazard maps indicate the extent
of expected risk areas, and can be combined with disaster management information
such as evacuation sites, evacuation routes, and so forth. (“KNOWLEDGE NOTE 5-
1 CLUSTER 5: Hazard and Risk Information and Decision Making Risk Assessment
and Hazard Mapping.” n.d.
https://www.preventionweb.net/files/29163_drmkn511.pdf.)

A Seismic Design Categories will help us in interpreting an earthquake map. The

following table describes the hazard level associated with each SDC and the
associated levels of shaking.

How to Read and Interpret an Earthquake Hazard Map?

The colors in the maps denote “seismic design categories” (SDCs), which reflect the
likelihood of experiencing earthquake shaking of various intensities.
The maps displayed below show how earthquake hazards vary across the United
States. Hazards are measured as the likelihood of experiencing earthquake shaking
of various intensities.

07/fema_hazard_maps_western-map_graphic.jpg.

Color white in the map indicates a very small probability of experiencing damaging
earthquake effects (low risk) while colored red in the map which is near major
active faults capable of producing the most intense shaking (high risk) as indicated
in the Seismic Design Categories.
On the other hand, there are also seven important components of a map. These
components will also help you read and interpret a map in the future.
1. Compass rose - This will give you the proper direction. This is also called it
“orientation.”
2. Title - It tells what the map is about.
3. Symbols - These are pictures instead of symbols.
4. Legend or Key - It explains the meaning of symbols and colour.
5. Colour - It highlights the important information to help interpret maps.
6. Scale - It shows the proportion of map to real life.

7 CO_Q1_DRRR SHS
Module 14
7. Grid Reference - These are intersecting lines to help locate specific places on the
map. In some maps, it is also called “border.”
