A disaster is defined as a hazardous event, either natural or man-made, that causes widespread damage and destruction of property or loss of life. There are two main types of disasters: natural disasters and man-made disasters. Natural disasters are the result of natural hazards like floods, tornadoes, earthquakes, or volcanic eruptions. They can lead to financial losses, environmental damage, and loss of human life depending on the vulnerability of the affected population.

![TWO TYPES OF DISASTER:
NATURAL DISASTER
A natural disaster is the effect of the earth's natural hazards, for
example flood, tornado, hurricane, volcanic
eruption, earthquake,heatwave, or landslide. They can lead to
financial, environmental or human losses. The resulting loss depends
on the vulnerability of the affected population to resist the hazard, also
called their resilience. If these disasters continue it would be a great
danger for the earth.[1]This understanding is concentrated in the
formulation: "disasters occur when hazards meet vulnerability."[2] Thus
a natural hazard will not result in a natural disaster in areas without
vulnerability, e.g. strong earthquakes in uninhabited areas.[3] The
term natural has consequently been disputed because the events
simply are not hazards or disasters without human involvement.[4] A
concrete example of the division between a natural hazard and a
natural disaster is that the 1906 San Francisco earthquake was a
disaster, whereas earthquakes are a hazard. This article gives an
introduction to notable natural disasters, refer to the list of natural
disasters for a comprehensive listing.](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

Disasters can be natural or man-made. Natural disasters include meteorological events like floods, droughts and tornadoes, topographical events like avalanches and landslides, and environmental catastrophes like volcanic eruptions and earthquakes. Developing countries are most vulnerable as over 95% of disaster deaths occur there. Disaster management aims to coordinate an organization's response through strategic planning rather than direct control. It focuses on reducing risks and vulnerabilities to minimize the harmful impacts of disasters.
Disaster
This document defines and provides examples of different types of natural and man-made disasters. It discusses natural disasters such as earthquakes, volcanic eruptions, floods, droughts and tornadoes. It also covers man-made disasters and technological hazards like industrial accidents, fires and oil spills. The document emphasizes that while hazards may occur naturally, it is the vulnerability of human settlements and lack of emergency management that turns these events into disasters that cause loss of life and property damage. Developing nations are often the most impacted due to greater exposure and fewer resources to build resilience against disasters.
Risky - categorising hazards
This document discusses categorizing and describing hazards. It defines hazards, disasters, and context hazards. Hazards can be categorized as hydro-meteorological, geophysical, or extra-terrestrial. Hazard profiles are used to describe key features of specific hazards. The interaction of hazards can complicate these categories. Risk is defined as the product of hazard and vulnerability, minus the capacity to cope. Keywords like vulnerability, disaster, and risk are also defined.
Disaster management
This document defines and classifies different types of hazards. It discusses natural hazards caused by geological, hydrological and ecological events like earthquakes, floods, volcanic eruptions, and cyclonic storms. Man-made hazards include those caused by human activities like nuclear explosions, chemical releases, and overpopulation. Hazards are further broken down into categories like planetary hazards from planetary orbits, endogenous hazards from internal Earth forces, and exogenous hazards from external space forces. Prevention focuses on sustainable environmental practices and disaster management planning.
Lesson 1.1 disaster and risk disaster
Disasters are defined as events that seriously disrupt society and cause widespread human, material, or environmental losses beyond what people can cope with using their own resources. Disaster risk refers to the likelihood of harm from hazards due to community or environmental vulnerabilities. Natural disasters originate from natural forces like volcanoes, earthquakes, typhoons, and fires, while human-made disasters are caused by human actions like war, bioterrorism, and industrial accidents involving nuclear power or hazardous materials.

The World At Risk
The document discusses natural hazards and disasters. It defines hazards as natural events that involve people, where social and environmental factors can turn an event into a disaster. There are two main classifications of hazards: hydro-meteorological hazards caused by weather patterns like floods and storms, and geophysical hazards caused by earth processes like earthquakes, volcanoes, and landslides. A disaster is defined as a natural event that causes human or economic losses. While the number of deaths from disasters has decreased due to better preparedness, the number of people affected and economic costs have risen due to increasing population in vulnerable areas and climate change impacts.

Natural Hazards, Classification and Analysis
An introduction to the concept of natural hazards,, a look at some of the ways they are classified and information about criteria used to analyze and compare natural hazards for Global Geography 12 at Charles P. Allen High School.
DISASTER AND ITS CAUSES
Natural disasters are events caused by natural hazards like floods, earthquakes, volcanoes, etc. that lead to damage and losses. The impact of a natural hazard depends on the vulnerability of the affected population - their ability to resist the hazard. While hazards exist naturally, it is human settlement and involvement that transforms them into disasters. Several types of natural hazards are described in detail, including earthquakes, landslides, tsunamis, volcanoes, floods, and thunderstorms. Common causes and effects of each hazard are summarized.
Risk
The document discusses risk from natural hazards and disasters. It defines risk as the probability of a hazardous event causing harmful consequences based on potential deaths, injuries, property damage, economic impacts, and environmental effects. Risk is determined by the interaction of hazards, vulnerability, and capacity to cope. Factors like involuntary hazards, immediate impacts, and deaths grouped in space and time tend to increase risk perception, while voluntary hazards, delayed impacts, and statistical victims tend to decrease risk perception. Individual responses to risk are influenced by experience, wealth, personality, and psychological denial. The document also lists the top 5 most dangerous earthquake hot spots in the US beyond California.
Disaster management
This document provides an overview of disaster management. It begins with definitions of key terms like disaster, hazard, and the types of natural and man-made disasters. Natural disasters discussed include floods, cyclones, earthquakes, and droughts. Man-made disasters include industrial accidents, fires, and wars. The document then focuses on floods, landslides, fires, and industrial pollution as examples. It describes the causes, effects, and types of these disasters. The goal of the document is to introduce concepts around disaster management.
Infrequent events
Rare events are events that occur with low or high frequency, and the term is often used in particular reference to infrequent or hypothetical events that have potentially widespread impact and which might destabilize society. Rare events encompass natural phenomena (major earthquakes, tsunamis, hurricanes, floods, asteroid impacts, solar flares, etc.).
World At Risk Global Hazards
Global hazards include hydro-meteorological hazards caused by climate processes like droughts and floods, and geophysical hazards caused by land processes like earthquakes and volcanic eruptions. The risk of disaster is determined by the hazard, a population's vulnerability, and their capacity to cope. While the number of geophysical hazards has remained steady, hydro-meteorological hazards are increasing due to global warming. Deaths from disasters have decreased due to improved risk management strategies like prediction, prevention, and preparedness, but global economic losses from disasters are rising rapidly.

AS Edexcel Geography - World At Risk
This document provides an overview of global hazards and trends related to climate change. It begins with key terms used to describe different types of hazards. Statistics show that while the number of deaths from disasters has decreased due to better protection, the total number affected has increased significantly since the 1990s. This is likely due to growing populations living in at-risk areas combined with more frequent or intense extreme weather events associated with climate change. El Niño/La Niña cycles also influence hazard patterns globally, bringing drought to some areas and floods to others. Human activities like deforestation exacerbate the impacts of disasters by increasing vulnerability.

Specific examples of climatic hazards mentioned include tornadoes, hurricanes, cyclones, droughts, El Nino events, acid rain, ozone depletion, smog, and how urban and rural environments can modify local climates. The document also examines factors that influence the impacts of these hazards on people, how humans respond to hazards, and defines key terms like forecast, prediction, risk, and vulnerability in the context of natural hazards.
toxicity-of-pesticides
This document discusses pesticide toxicity and exposure. It explains that toxicity is determined by an pesticide's ability to cause harm, while exposure depends on how the pesticide enters the body through skin, mouth, lungs, or eyes. Common pesticides like organophosphates and carbamates interfere with the nervous system and can cause acute or chronic health effects from both large and small repeated exposures. Proper use of personal protective equipment and understanding pesticide labels is important for minimizing health risks.
Socio economic impacts of natural disasters
Natural disasters have significant socio-economic impacts that vary depending on whether they occur in a less economically developed country (LEDC) or more economically developed country (MEDC). In LEDCs, disasters can have more severe consequences due to factors like lower GDP, weaker infrastructure, lack of resources, and unstable governments. This hinders recovery efforts. Major international aid organizations like the UN and Red Cross provide relief in disasters worldwide, but their assistance is also more crucial in LEDCs with limited response capacities. The wealth and development level of a nation therefore influences the scale of damage and recovery from natural hazards.

OSHA Hazard Communication and Global Harmonization System (GHS)
This training explains the recent changes to the OSHA Hazard Communication Standard, including compliance with the Global Harmonization System of hazard identification, container labeling, and Safety Data Sheets.
Noise Pollution
Noise Pollution is defined as any undesirable human or machine created noise which disturbs human or animal activity or balance. It is measured in decibels (dB) which is a logarithmic ratio of sound pressures. Prolonged exposure to loud noise can cause permanent hearing loss, annoyance, stress, and disrupted sleep and human performance. Noise pollution affects animals through hearing loss, physiological stress, and disruption of behavior and ecosystems. Plants are also impacted through reduced growth. Control measures include reducing noise at the source through improved machinery and mufflers, zoning of industrial areas away from homes, sound insulation of buildings, use of ear protection, legislative bans on loud noises, and planting trees.

Disaster Management.pptx
The document discusses different types of disasters, including natural disasters caused by geological, hydrological, climatological, meteorological, biological, and space events; human-made or technological disasters resulting from environmental degradation, pollution, terrorism, and accidents; and complex emergencies involving food insecurity, epidemics and pandemics, and displaced populations impacted by multiple disasters. Natural disasters are broadly classified according to their origin or cause, while human-made disasters typically involve human activity or negligence and can exacerbate the impacts of natural disasters. Complex emergencies incorporate elements of both natural and human-made disasters that overwhelm local capabilities.
Disaster Management and Health
A disaster is a natural or man-made hazard that causes substantial damage and destruction. Disasters disproportionately impact developing countries due to greater vulnerabilities and risks. Disaster management aims to reduce the impacts of disasters through preparedness, mitigation and response. It involves coordinating response efforts at all levels to provide emergency aid and meet basic needs in disaster-stricken areas. Effective disaster management relies on thorough emergency planning and response coordination among different organizations.
EVS-MOD-4.ppt
Natural hazards such as earthquakes, tsunamis, cyclones, and floods are discussed in the document. Earthquakes occur due to disequilibrium in the earth's crust and can cause severe damage to infrastructure and loss of life. Tsunamis are large waves generated by seismic activity or landslides that can devastate coastal areas. Cyclones are intense storms that form over oceans and bring powerful winds and rains. Floods occur when heavy rainfall or dam/embankment breaches cause rivers to overflow their banks. The document outlines the types and effects of these natural disasters.

Disaster preparedness & mitigation
This document discusses disaster preparedness and mitigation. It defines a disaster as an event that causes damage, disruption, loss of life or health deterioration on a large scale. Disasters can be natural, caused by events like earthquakes, floods and volcanoes, or man-made like terrorism or civil unrest. Key components of disaster management are preparedness, response, recovery and prevention/mitigation. Preparedness involves ensuring communities can cope with disasters through education, warning systems and drills. Response requires measures during and after disasters to minimize effects. Recovery aids emergency areas with infrastructure and economic rebuilding. Prevention eliminates or reduces disaster incidence and severity through risk avoidance and disaster-resistant infrastructure.
Disaster
A disaster is defined as a serious disruption to a community or society that exceeds its ability to cope using its own resources. Disasters can be caused by natural hazards like earthquakes, floods, or hurricanes, or human-instigated events like industrial accidents, fires, or acts of terrorism. Developing countries are particularly vulnerable to disasters as they suffer over 95% of disaster related deaths and losses that are 20 times greater than developed countries as a percentage of GDP. Disasters occur when a hazard impacts a vulnerable population or infrastructure.

What is disaster?
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Developing countries suffer the greatest costs when a disaster hits – more than 95% of all deaths caused by hazards occur in developing countries, and losses due to natural hazards are 20 times greater (as a percentage of GDP) in developing countries than in industrialized countries.
The word disaster is derived from Middle French désastre and that from Old Italian disastro, which in turn comes from the Ancient Greek pejorative prefix δυσ-, (dus-) "bad"and ἀστήρ (aster), "star".The root of the word disaster ("bad star" in Greek) comes from an astrological sense of a calamity blamed on the position of planets.
Disasters are routinely divided into natural or human-made, although complex disasters, where there is no single root cause, are more common in developing countries. A specific disaster may spawn a secondary disaster that increases the impact. A classic example is an earthquake that causes a tsunami, resulting in coastal flooding. Some manufactured disasters have been ascribed to nature such as smog and acid rain.
Some researchers also differentiate between recurring events such as seasonal flooding, and those considered unpredictable.
2. Natural disasters
A natural disaster is a natural process or phenomenon that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage.
Various phenomena like earthquakes, landslides, volcanic eruptions, floods, hurricanes, tornadoes, blizzards, tsunamis, cyclones, wildfires, and pandemics are all natural hazards that kill thousands of people and destroy billions of dollars of habitat and property each year.[10] However, the rapid growth of the world's population and its increased concentration often in hazardous environments has escalated both the frequency and severity of disasters. With the tropical climate and unstable landforms, coupled with deforestation, unplanned growth proliferation, non-engineered constructions make the disaster-prone areas more vulnerable. Developing countries suffer more or less chronically from natural disasters due to ineffective communication combined with insufficient budgetary allocation for disaster prevention and management.

Disaster presentation
- 1. A disaster 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. A disaster can be ostensively defined as any tragic event stemming from events such as earthquakes, floods, catastrophic accidents, fires, orexplosions. It is a phenomenon that disasters can cause damage to life, property and destroy the economic, social and cultural life of people..
- 2. TWO TYPES OF DISASTER: NATURAL DISASTER A natural disaster is the effect of the earth's natural hazards, for example flood, tornado, hurricane, volcanic eruption, earthquake,heatwave, or landslide. They can lead to financial, environmental or human losses. The resulting loss depends on the vulnerability of the affected population to resist the hazard, also called their resilience. If these disasters continue it would be a great danger for the earth.[1]This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability."[2] Thus a natural hazard will not result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas.[3] The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement.[4] A concrete example of the division between a natural hazard and a natural disaster is that the 1906 San Francisco earthquake was a disaster, whereas earthquakes are a hazard. This article gives an introduction to notable natural disasters, refer to the list of natural disasters for a comprehensive listing.
