About This Presentation
Vulnerabilities associated with different elements can vary widely depending on the context—whether you're referring to chemical elements, natural elements (like earth, water, air, fire), or elemental associations in a broader sense. Here's a breakdown:

Vulnerabilities associated with different elements can vary widely depending on the context—whether you're referring to chemical elements, natural elements (like earth, water, air, fire), or elemental associations in a broader sense. Here's a breakdown:
1. Chemical Elements:
Hydrogen (H): Highly flammable and can form explosive mixtures with air.
Oxygen (O): Supports combustion; can enhance the flammability of materials.
Sodium (Na): Reacts violently with water, producing hydrogen gas and caustic sodium hydroxide.
Chlorine (Cl): Toxic gas; exposure can cause respiratory and skin irritation.
Mercury (Hg): Toxic to humans and animals; exposure can cause neurological damage.
Lead (Pb): Toxic; accumulates in the body and can cause various health problems.
Uranium (U): Radioactive; exposure can lead to radiation sickness and long-term health issues.
2. Natural Elements (Earth, Water, Air, Fire):
Earth: Vulnerable to erosion, landslides, and earthquakes.
Water: Vulnerable to contamination (e.g., pollution, toxins) and flooding.
Air: Vulnerable to pollution (e.g., smog, particulate matter) affecting respiratory health.
Fire: Vulnerable to wildfires, especially in dry conditions.
3. Elemental Associations (Traditional Elements):
Earth (or Ground): Vulnerable to disruptions like earthquakes, landslides, or soil erosion.
Water: Vulnerable to floods, tsunamis, or contamination affecting aquatic life.
Air: Vulnerable to air pollution, hurricanes, tornadoes, or disruptions in the atmosphere.
Fire: Vulnerable to wildfires, volcanic eruptions, or extreme heat conditions.
Understanding vulnerabilities associated with different elements is crucial for risk assessment, disaster preparedness, and environmental management. The specific vulnerabilities will vary depending on the element's properties, interactions, and environmental factors.

Vulnerabilities of Different Elements Exposed to Hazards
Vulnerability can determine the ability of a person or a group to predict, cope with, resist and recover from the effects of a natural or human-induced threat. Vulnerability is a state of being at risk. According to Republic Act 10121 also known as ‘Philippine Disaster Risk Reduction and Management Act of 2010’ , vulnerability is defined as the characteristics and circumstances of a community, system or resource that make it susceptible to the damaging effects of a hazard.
Factors affecting vulnerability of one’s community: A. Population density near a hazard event. The primary consideration is not the population size but the population density.
B. Capacity and efficiency to reduce Disaster Risk. Community that is less vulnerable has the capacity to reduce disaster risk because; 1. It can provide accessibility and availability of services and facilities during and after disaster. 2. It has the ability to anticipate, adapt, and respond to possible disaster.
Recognize Vulnerabilities of Different Elements Exposed to Specific Hazards. Vulnerabilities of different elements are determined due to its exposure to particular and specific hazard. Physical vulnerability includes population density levels, place of a settlement, the site design, and materials used for infrastructure and housing.
Social Vulnerability happens due to inability of people, organization, and societies to prevent severe effects from hazards because of the expected behavior in social interactions, institutions, and system of cultural values.
ECONOMIC VULNERABILITY - is based on the economic status of individuals, communities, and nations. Social and economic vulnerability can be combined also known as socioeconomic vulnerability.
Environmental vulnerability is caused by natural resources depletion and destruction. Organisms like humans, animals, and plants are all dependent on the environment for survival. Quantifying vulnerability is used in estimating how much mitigation and preparedness measures will be applied.
The Philippines has high vulnerability due to the following reasons: • It lies in the Pacific typhoon belt and we are visited by an average of 20 typhoons every year. • Rugged nature of the landscape makes it vulnerable to landslide, mudflows, and other disasters. • It is an archipelagic country with many small islands where some areas are at below sea level.
• It has the longest shoreline in the world at 32,400 km making it vulnerable to storm surges. • It is still a primary agricultural and fishing economy. • With poor institutional and social capacity to manage, respond, and recover from natural hazard events. • With high level of poverty • Aside from typhoon, it is also at risk to volcanic eruptions, quakes, and floods.
Direction: Identify what factor affects the vulnerability to disaster with the following situations given. Write P if it is due to population density and write C if it is due to sector’s capacity and efficiency to reduce disaster risk. Write your answer on a separate sheet of paper. 2. Use of drones to disinfect the community in Pasig City to prevent the spread of the COVIDD-19 virus. 1. Tondo community during the total lockdown due to COVID-19 pandemic wherein the families are forced to stay inside their houses that are too small for the number of family members.
5. The Philippines and Japan are both prone to earthquakes but the latter one is less vulnerable. 3. Insufficient number of rubber boats during super typhoon Yolanda in Malabon City wherein large number of residents were stranded on the top of their roof. 4. Too many casualties during super typhoon Milenyo in Los Baños due to excessive kaingin practices and illegal settlers in Mt. Makiling .
Direction: Classify the following phrases and sentences whether it is PHYSICAL, SOCIOECONOMICAL OR ENVIRONMENTAL VULNERABILITY . 1. Shutdown of telecommunication tower 2. Houses built near fault lines 3. Denudation of forests 4. Rest houses near boracay shoreline 5. Twenty-story building constructed on soil mainly made up of clay. 6. Bridges with cracks and crevices 7. Overfertilization of agricultural soil 8. Lost of job due to COVID-19 pandemic. 9. Possible retrenchment of ABS CBN employees due to its shutdown 10.Destruction of coral reefs that serves as barriers against storm surge.
