What’s New

Natural disasters can come like a thief in the night, unexpected and

unpredictable. Many lives are in great danger if these disasters are not well prepared

by the community. In the Philippines, the most common are earthquakes and

typhoons. Is your family disaster risk ready?

How did you find the previous activity? Did you find a lot of hazardous areas in

your home? If so, you need to create a family emergency plan to protect your

loved ones. Remember, prevention is always better than cure.

Activity: Creating a Family Emergency Plan

Fill in the form below to create your own family emergency plan. After filling in

the form, share the information with your family and remember to bring it with

you all the time.

Living on a planet that constantly changes itself, the different climatic, seismic,

volcanic, hydrologic and meteorological events that often occur in all parts of the world

poses hazards. A natural hazard is a natural-occurring event or phenomenon which

has negative environment effects. Natural disaster refers to any natural hazard or

threat that causes fatality or damage to property.

Earthquake and Typhoon Preparedness

Before

The key to effective disaster prevention is planning

- Follow structural design and engineering practices when constructing a house or building. Ensure that house can withstand heavy rain, strong winds and earthquakes

- Engage yourself in training activities that promote safety and disaster preparedness.

o Know the earthquake hazards in your area o Learn more about typhoons and other weather disturbances, their signs

and warnings, effects and dangers o Participate actively in school’s disaster response- drill or simulation

Prepare your homes, workplace or schools

- Strap or bolt heavy furnitures/ cabinets to the walls

- Check the stability of hanging objects like ceiling fans and chandeliers

- Breakable items, harmful chemicals and flammable materials should be stored properly in the lowermost secured shelves

Familiarize yourself with the exit routes

- Know where fire extinguishers, first aid kits, alarms, and communication facilities are located. Learn how to use them beforehand

- Prepare a handy emergency supply kit with first aid kit, canned food and can opener, water, clothing, blanket, battery-operated radio, flashlights and extra batteries

- DURING

Stay Calm

When you are INSIDE a structurally sound building or home

Stay there!

Do the “DUCK, COVER and HOLD” (Figure 2)

- If possible quickly open the door for exit

- Duck under a sturdy desk or table, and hold on to it, or protect your head with your arms

- Stay away from glass windows, shelves, cabinets and other heavy objects

- Beware of falling objects. Be alert and keep your eyes open

If you’re OUTSIDE,.. move to an open area!

- Stay away from trees, powerlines, posts and concrete structures

- Move away from steep slopes which may be affected by landslides

- If you’re near the shore and feel an earthquake, especially if it’s too strong, move quickly to higher grounds. Tsunamis might follow

If you’re in a moving vehicle in case of earthquakes, STOP and get out! Do not attempt

to cross bridges, overpasses, or flyovers which may have been damaged

In case of typhoons, monitor through radio or other reliable sources the official report

of PAGASA on the typhoon.

AFTER

In case of earthquakes, be prepared for aftershocks. Once the shaking stops, take the

fastest and safest way out of the building

Figure 2. Duck, Cover, and Hold

8

Don’t …

…Use elevators

…enter damaged buildings

…use telephones unless necessary

…PANIC

Check yourself and others for injuries

Check water and electrical lines for damages

Check for spills of chemicals, toxic and flammable materials

Check control fires which may spread

If you need to evacuate your residence, leave a massage stating where you are going

and bring your emergency supply kit.

Keep updated on disaster prevention instructions from battery-operated radios

A typhoon is a large, powerful and violent tropical cyclone. It is a low pressure

area rotating counter clockwise an containing rising warm air that forms over warm

water in the Western Pacific Ocean. Because Philippines is always frequented with an

average of 20 tropical cyclones, PAGASA issues public weather forecasts and

advisories called PUBLIC STORM WARNING in several mass media to provide

warnings related to weather conditions as summarized in table 1 below.

Table 1.Public Storm Warning Signals

Table 1 Public Storm Warning System

Level Wind and Lead Time

1 30-60 km/h; within 36 hours

2 60-120 km/h; within 24 hours

3 120-170 km/h; within 18 hours

4 170-220 km/h; within 12 hours

5 Faster than 220 km/h; within 12 hours

Using PAGASA`s PSWS, the Department of Education (DepEd) has adopted

the following guidelines with regards to class suspension.

- PSWS 1 – All classes in kindergarten are suspended

- PSWS 2 - All classes in elementary and high school are suspended

- PSWS 3 – All classes in all levels, including college and graduate schools are suspended

9

Aside from the PSWS, PAGASA also provides color-coded rainfall warning

system (as seen in Figure 3) in their storm forecasts to help communities prepare for

incoming heavy rain and potential flooding and act accordingly.
