HAZARDS, DISASTERS, RISKS ENM 41- Disaster Risk Reduction Management FELINO J. GUTIERREZ, Jr., PhD Assistant Professor Forestry & Environmental Science Department SOUTHERN LUZON STATE UNIVERSITY HAZARDS A process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation. They can be single, sequential, or both, based on their origin and impacts. Characterized and identified by its Location, Magnitude or intensity Probability and Frequency of occurrence. SOUTHERN LUZON STATE UNIVERSITY TYPES Natural Hazards Associated with natural processes and phenomena such as typhoon Anthropogenic hazards Human-induced hazards or induced entirely or predominantly by human activities and choices. Does not include occurrence of risk of armed conflicts and other situations of social instability or tension that area subject to international humanitarian law and national legislation. Socio-natural Associated with a combination of natural and anthropogenic factors including degradation and climate change. SOUTHERN LUZON STATE UNIVERSITY Description of Hazard Types Hydrometeorological hazards are of atmospheric, hydrological or oceanographic origin. Hydrometeorological conditions may also be a factor in other hazards such as landslides, wildland fires, locust plagues, epidemics and in the transport and dispersal of toxic substances and volcanic eruption material. Technological hazards originate from technological or industrial conditions, dangerous procedures, infrastructure failures or specific human activities. SOUTHERN LUZON STATE UNIVERSITY Biological hazards are of organic origin or conveyed by biological vectors, including pathogenic microorganisms, toxins and bioactive substances Environmental hazards may include chemical, natural and biological hazards. They can be created by environmental degradation or physical or chemical pollution in the air, water and soil. Geological or geophysical hazards originate from internal earth processes. Tsunamis are difficult to categorize although they are triggered by undersea earthquakes and other geological events.

SOUTHERN LUZON STATE UNIVERSITY Disaster “A calamity or catastrophic event that occurred in an area that affected life and properties” (Baluasubramanian, 2014). A serious disruptions of the functioning of a community or a society, at any scale due to hazardous events interacting with conditions of exposure, vulnerability and capacity, leading to one or more of the following: human, material, economic, and environmental losses and impacts (UNDRR) SOUTHERN LUZON STATE UNIVERSITY Water Induced Disasters Floods, avalanche, landslides, and debris flow Glacial lake outburst floods- result of global warming, hydrological and seismic factors. Heavy rainfall that caused landslides and erosions in riverbanks. For some literatures, drought is considered a water related disasters that affects the economic and social aspects with insufficient preparedness. SOUTHERN LUZON STATE UNIVERSITY SOUTHERN LUZON STATE UNIVERSITY Meron bang Natural Disaster? There is no such thing as a natural disaster, but disasters often follow natural hazards (UNDRR). “using ‘natural’ to describe disasters can give people the impression that disasters are inevitable, and that human agency can do little to prevent or mitigate their impacts. “A natural hazard becomes a disaster when it combines with exposure and vulnerability to cause loss of life, hurt and injury to people, along with economic loss.” SOUTHERN LUZON STATE UNIVERSITY RISK “The potential loss of life, injury, or destroyed or damaged assets which could occur to a system/community, in a certain time period” (UNDRR, 2020) The consequence of the interaction between a hazard and the characteristics that make people and places vulnerable and exposed. The combination of the severity and frequency of a hazard, the numbers of people and assets exposed to the hazard, and their vulnerability to damage. SOUTHERN LUZON STATE UNIVERSITY SOUTHERN LUZON STATE UNIVERSITY SOUTHERN LUZON STATE UNIVERSITY VULNERABILITY Vulnerability “The characteristics determined by physical, social, economic and environmental factors or processes which increase the susceptibility of an individual, a community, assets or systems to the impacts of hazards.” Vulnerability is the human dimension of disasters and is the result of the range of economic, social, cultural, institutional, political and psychological factors that shape people’s lives and the environment that they live in. Understanding vulnerability requires more than analyzing the direct impacts of a hazard. Vulnerability also concerns the wider environmental and social conditions that limit people and communities to cope with the impact of hazard. Vulnerability analysis involves understanding the root causes or drivers of vulnerability, but also people's capacities cope and recover from disasters. SOUTHERN LUZON STATE UNIVERSITY Factors Affecting Vulnerability Physical Factors Poor design and construction of buildings, unregulated land use planning Social Factors Poverty and inequality, marginalization, social exclusion and discrimination by gender, social status, disability, age, and psychological factors Economic factors Uninsured informal sector, vulnerable rural livelihoods, dependence on single industries, globalization of business and supply chains Environmental Factors Poor environmental management, overconsumption of natural resources , decline of risk regulation ecosystem services, climate change SOUTHERN LUZON STATE UNIVERSITY Vulnerability is also determined by historical, political cultural, and instititutional processes Levels of vulnerability (and exposure) help to explain why some non extreme hazards can lead to extreme impacts and disasters, while some extreme events do not. It is often people’s vulnerability that is the greatest factor in determining their risk. Different groups are more susceptible to hazard risks, but also some have higher level of vulnerability than others. Vulnerable groups have difficulty to impacts of subsequent hazard events Reducing vulnerability could reduce disaster risk. SOUTHERN LUZON STATE UNIVERSITY EXPOSURE Exposure “The situation of people, infrastructure, housing, production capacities and other tangible human assets located in hazard prone areas.” (UNDRR) SOUTHERN LUZON STATE UNIVERSITY SOUTHERN LUZON STATE UNIVERSITY Is it possible to be exposed but not be vulnerable (susceptible) to hazards? Levels of vulnerability (and exposure) help to explain why some non-extreme hazards can lead to extreme impacts and disasters, while some extreme events do not.

The majority of Earth’s volcanoes and earthquakes take place along the Ring of Fire. Seventy-five percent of Earth’s volcanoes—more than 450 volcanoes—are located along the Ring of Fire. Ninety percent of Earth’s earthquakes occur along its path, including the planet’s most violent and dramatic seismic events.
