At the end of this lesson, students are expected to: Learning Outcomes.

Afi. It is the process of protecting the livelihoods and assets of communities and individuals from the impact of hazards. What is Disaster Risk Reduction (DRR)?.

II. • Is a dangerous phenomenon, substance, human activity, or condition that may cause loss of life, injury or other health impacts, property damage, loss of livelihood & services, social & economic disruption, or environmental damage. • Could be a potentially damaging phenomenon • It could be natural or human-induced.

• The degree to which the elements at risk are likely to experience hazard events of different magnitude..

• Is the characteristics and circumstances of a community, system, or asset that make it susceptible to the damaging effects of a hazard. • This may arise from environmental factors..

• Is the combination of all strengths and resources available within the community, society, or organization that can reduce the level of risk or effects of a disaster..

• Is the combination of the Probability of an event to happen and its negative consequences..

TRIAGRAM OF DISASTER RISK. RISK. Hazard. Vulnerability.

What is disaster ?. It is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment..

CLASSIFICATION OF DISASTER. A natural disaster is a consequence when a natural hazard affects humans and/or the built environment. Human vulnerability, and lack of appropriate emergency management, lead to financial, environmental, or human impact. The resulting loss depends on the capacity of the population to support or resist the disaster: their resilience. This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability". A natural hazard will hence never result in a natural disaster in areas without vulnerability.

CLASSIFICATION OF DISASTER. Man-made disasters are the consequence of technological or human hazards. Examples include stampedes, fires, transport accidents, industrial accidents, oil spills, and nuclear explosions/radiation. War and deliberate attacks may also be put in this category. As with natural hazards, man-made hazards are events that have not happened, for instance, terrorism. Man-made disasters are examples of specific cases where man-made hazards have become reality in an event..

When is an event a disaster? Why are disaster impacts increasing?.

DISASTER PREPAREDNESS. Republic Act No. 10121 otherwise known as PDRRM ACT of 2010 An Act Strengthening the Philippine Disaster Risk Reduction and Management System, Providing for the National Disaster Risk Reduction and Management Framework, Institutionalizing the National Disaster Risk Reduction and Management Plan, Appropriating Funds Therefore, and for Other Purposes..

1. Mitigation - Minimizing the effects of disaster. Examples: building codes and zoning; vulnerability analyses; public education. 2. Preparedness - Planning how to respond. Examples: preparedness plans; emergency exercises/training; warning systems. 3. Response - Efforts to minimize the hazards created by a disaster. Examples: search and rescue; emergency relief . 4 PILLARS OF DISASTER RISK REDUCTION.

4. Recovery - Returning the community to normal. Examples: temporary housing; grants; medical care. 4 PILLARS OF DISASTER RISK REDUCTION.

An earthquake is a sudden release of energy along a fault in the Earth's crust. Earthquake It poses a severe threat because of its irregular intervals and difficulty to forecast..

Before an earthquake Review your family preparedness plan. Establish a family communications plan. Assemble an earthquake kit. During an earthquake.

After an earthquake Be prepared for aftershocks. Although smaller than the main shock, aftershocks can cause additional damage and bring weakened structures down. Aftershocks can occur in the first hours, days, weeks or even months after the quake. Listen to a radio or TV for updated information. When the shaking stops, look around. If there is a clear path out, leave the building and head for an open area. Avoid making phone calls except in serious emergencies. Help injured or trapped people. Do not move seriously injured people unless they are in immediate danger of death or further injury. Call for help. Stay out of damaged homes, and follow the directions of emergency officials.

Floods and flashfloods are common products of torrential rains especially if it occurs after a long period of dry conditions. Flood/ Flashflood Dam breaks can also result to flooding, and can severely affect the communities nearby..

Before a flood or flash flood Find out if you live in a flood-prone area and whether your property is above or below the flood stage water level. Elevate your furnace, water heater and electric panel. If time permits, use sandbags to construct barriers to protect your home. Consider installing “check valves” to prevent floodwaters from backing up into the drains of your home. Be familiar with flooding warning signs: - Consistent heavy rains. - Overflowing rivers and streams. - Saturated ground..

During a flood or flash flood Listen to a NOAA weather radio for updated information. If time permits, move valuable possessions to upper floors or safe ground. Be prepared to evacuate, and do so immediately if necessary. Do not walk or drive through any floodwaters. After a flood or flash flood Continue listening to a NOAA weather radio for updated information. Avoid damaged areas, stay off roads and remain on firm ground. Avoid floodwaters. The water may be contaminated. Return home only after local officials declare it is safe. Enter your home with extreme caution. Do not enter if floodwaters remain..

The movement of a mass of rock, debris, or earth down a slope. Landslides.

Before a landslide/debris flow Check out FLASH Hurricane Strong for do-it-yourself ways to strengthen your homes against flooding, high winds and lightning. Review your family preparedness plan. Establish a family communications plan. Assemble a disaster supply kit. Have a family evacuation plan in place. Perform a ground assessment of your property, and consult a professional for advice on appropriate preventive measures. Learn the history of landslides and debris flows in your area. Never build a home where landslides and debris flows have occurred in the past. They are likely to occur again..

Minimize hazards: - Plant ground cover on slopes. Use erosion-preventing plants such as yucca, bamboo, vetiver grass, etc. - If possible, build retaining walls, channels or deflection walls around your home. During a landslide/debris flow Be prepared to evacuate and do so immediately if necessary. If you are inside, remain where you are and take cover under a sturdy piece of furniture. If you are outside, run to the nearest high ground away from the landslide or debris flow. If escape is not possible, curl into a tight ball to protect your head..

After a landslide/debris flow Stay away from the slide area. There could be additional slides. Avoid using the phone except in serious emergencies. Remember that flooding may occur after a landslide or debris flow. Help injured or trapped people. Do not move seriously injured people unless they are in immediate danger of death or further injury. Call for help..
