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.
Disasater
This document defines and describes different types of disasters. It defines a disaster as a sudden event that disrupts a community beyond its ability to cope using its own resources. It defines disaster management as organizing resources to deal with emergencies and reduce disaster impacts. It describes natural disasters like floods, hurricanes and earthquakes that can immediately harm health and cause further death. It also discusses man-made disasters resulting from human error that often cause wide-scale destruction, and hybrid disasters where human actions increase damages from natural or man-made hazards.
Effects of natural disasters
Natural disasters such as volcanic eruptions, earthquakes, floods, and tornadoes can have significant environmental, economic, and human impacts. They often permanently alter the local landscape and can lead to the destruction of local species. Even minor storms can cause considerable economic damage through infrastructure destruction and business interruption. Beyond direct impacts, natural disasters also cause indirect effects like utility disruptions and emotional tolls like anxiety, depression, and post-traumatic stress. The loss of lives and homes creates further hardships for victims. Overall, natural disasters have wide-ranging consequences on environments, economies, and human well-being.
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.
Basic concept of Hazards
Here are the answers to your questions:
1. An earthquake is a shaking or trembling of the earth that is caused by the breaking and shifting of rock beneath the earth's surface. Earthquakes can cause buildings and bridges to collapse and trigger other hazards like landslides, tsunamis or volcanic eruptions.
2. The different types of earthquake hazards include:
- Ground shaking - The sudden shaking and movement of the ground during an earthquake is the main cause of damage and can destroy buildings and infrastructure. The severity of ground shaking depends on the magnitude of the earthquake, the distance from the epicenter and the local geology.
- Surface faulting - Some earthquakes may cause visible cracks or breaks in the ground
Natural Hazards and Disasters
The document discusses natural hazards and disasters around the world. It identifies common natural hazards such as floods, windstorms, earthquakes, tsunamis, droughts and volcanic eruptions. Specific hazards are also discussed for regions like Asia, the Pacific Ring of Fire, China, India and Japan. Models are presented for how natural disasters occur when hazards overwhelm a community's capabilities, and how risk from hazards is determined by vulnerability and capacity to cope. Key terms like hazard, vulnerability and risk are defined.

Natural disasters and its managment
A natural disaster is the effect of earths 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
Impact of disaster on social, economic and physical fabric
Disasters can seriously disrupt communities by exceeding their ability to cope using available resources. The 2015 earthquakes in Nepal killed over 5,000 people and caused an estimated $10 billion in economic losses. Impacts included widespread unemployment, loss of livelihoods, and damage to public infrastructure and private property. The disasters also disrupted social systems through family disorganization, increased risk of violence and abuse, and changes in marital and living situations.
Natural disaster powerpoint
Natural disasters can severely injure or kill people and cause immense property damage. In 2010, natural disasters killed 295,000 people and cost insurers $218 billion globally. The 2011 Tsunami and earthquake in Japan killed over 10,000 people, while Hurricane Katrina in 2005 alone caused $81 billion in property damage to New Orleans, flooding 80% of the city under 15 feet of water and reducing the city's population. While natural disasters cannot be prevented, organizations help with relief efforts, rebuilding, and preparing for aftermaths that can include landslides and fires.

Natural Disasters
India experiences many natural disasters that cause loss of life and property damage. Some key points:
- India averages over 4,600 deaths per year from disasters like earthquakes, floods, landslides, cyclones and heat waves. Over 1.5 billion people are affected on average each year.
- Economic damage from disasters averages over $1.5 billion per year. Some of the costliest individual disasters include the 1993 floods ($7 billion), 2006 floods ($3.39 billion), and the 2001 earthquake ($2.62 billion).
- The document concludes that India is not fully prepared to handle national disasters due to the widespread impacts experienced. Preparedness needs to be improved to better cope with future disasters.
Hazard
The document defines hazards as objects, conditions, or events that threaten injury, damage to property, or the environment. Hazards can be natural, caused by phenomena like earthquakes, or man-made such as industrial accidents. Vulnerability refers to factors that increase susceptibility to harm from hazards. Risk is the probability that a hazard will negatively impact vulnerable areas or people. A disaster occurs when a hazard affects a vulnerable population or area, exceeding its ability to cope and resulting in widespread losses.
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.
Project on Disaster Management
This document discusses a student's school project on disaster management. It provides an introduction to different types of disasters, including natural disasters like floods, earthquakes, tornadoes, and tsunamis.

1) Japan experiences frequent earthquakes due to tectonic plate interactions, which have caused major disasters like the 1923 Great Kanto Earthquake and 2011 Tohoku Earthquake.
2) Lessons from past quakes show that preparedness, protection of buildings, and emergency response capacity are essential for community resilience against earthquakes and tsunamis.
3) The next major earthquake anticipated in Japan is the Tokai Earthquake along the Nankai Trough, estimated to cause billions in damage and thousands of deaths. Monitoring is underway to provide early warning.Chapter 1 Plate Tectonics Power Point
The document discusses Earth's structure and plate tectonics. It describes how Earth formed layers with different densities, including the inner and outer core, mantle, crust, and lithosphere. The lithosphere is made up of tectonic plates that move over time. There are three types of plate boundaries - divergent where plates move apart, convergent where they push together, and transform where they scrape past each other. Plate tectonics explains how continents have changed positions over billions of years and continue to move today.
Natural disasters' Impacts & Prevention
A natural disaster is a major event caused by natural hazards that affects the environment and leads to financial, environmental, and human losses. Common natural disasters include floods, tsunamis, tornadoes, hurricanes, cyclones, volcanic eruptions, earthquakes, heatwaves, droughts, wildfires, landslides, blizzards, ice storms, and avalanches. Earthquakes, floods, and volcanic eruptions are among the natural disasters that cause the most deaths. Natural disasters can have significant individual, community, economic, and environmental impacts. While not all natural disasters can be prevented, understanding ecology and taking strategies from nature can help lessen their effects.

Disaster management ppt
Disaster management involves dealing with and avoiding both natural and man-made disasters through preparedness, response, recovery, and mitigation efforts. It aims to reduce vulnerabilities and impacts through organized and sustained actions to analyze and manage hazards and the underlying risks. Key aspects of disaster management include preparedness before a disaster through activities like risk assessment, warning systems, and stockpiling resources; immediate response efforts during an event; and long-term rehabilitation and reconstruction work after an event to support regrowth. Effective disaster management requires coordination and planning across different levels of government, organizations, and communities.

Definition of disaster and disaster risk
Disasters are defined as sudden events that cause great damage and loss of life and property. They can be natural, caused by forces like earthquakes, floods, or hurricanes, or human-caused by things like explosions, accidents, or terrorism. Disaster risk refers to the probability that a hazard will damage infrastructure or disrupt a community based on its construction and location. Disasters are categorized as either natural or human-made, and can range from short events to ones lasting days or weeks with ongoing destruction. They include natural hazards like storms, earthquakes, wildfires, and human or technological threats such as hazardous materials, power outages, explosions, or cyber attacks.
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.
Disasters and Management
This document discusses environmental disaster management. It defines key terms like disaster, disaster management, and discusses different types of disasters classified by cause (natural or man-made) and speed of onset (sudden or slow). The disaster cycle and models for disaster management involving prevention, mitigation, preparedness, response, rehabilitation and reconstruction are explained. Factors influencing risk like hazards, vulnerability and capacity are also defined.

Disaster management By vivek bhatt
India is vulnerable to both natural and human-induced disasters. Natural disasters that commonly occur in India include floods, cyclones, earthquakes, landslides, and droughts. These disasters can be categorized as slow-onset like droughts or rapid-onset like earthquakes. They cause widespread damage and disruption. India has developed systems for disaster management but remains at risk given factors like its large population, urbanization, and effects of climate change. The economically weak face greater vulnerabilities during disasters. After disasters, rehabilitation and reconstruction aim to restore affected communities while encouraging necessary adjustments. Various agencies in India are responsible for managing different types of disasters.
A What is Disaster and Disaster Risk.pptx
The document defines disaster as a sudden, calamitous occurrence that causes great harm, injury, destruction, and devastation to life and property. Disasters can be minor, major, or cause total destruction and death. Disasters are also defined as serious disruptions involving widespread losses that exceed a community's ability to cope. Disasters are divided into natural disasters, caused by forces like earthquakes, typhoons, and droughts, and human-made disasters caused by technological failures, terrorism, or complex emergencies. The document asks whether COVID-19 is a natural or human-made disaster and provides a list classifying different types of disasters as natural or man-made.
WEEK-1-DISASTER-RISK-ON-AIR.pptx
The main difference between hazard and disaster is that hazard is a dangerous situation or event that poses a threat to humans while disaster is an event that actually harms human’s life, property and thus disrupts social activities.
Therefore, a hazard can lead to a disaster that will completely disrupt the life conditions of the victims. However, both hazard and disaster bear potential threat to humans since both can result in loss and damage to life and property. A disaster is more critical in nature than a hazard, which might turn into a disaster in extreme circumstances.
What is a Hazard?
Hazard is a general occurrence that is risky or dangerous to the affected people. Therefore, they are naturally occurring situations in the world, which cannot be avoided. Furthermore, they pose a threat to our lives.
There are two types of hazards as geophysical and biological. Some geophysical hazards are earthquakes, volcanic eruptions, droughts, floods, and some biological hazards are disease, infection, etc.
Based on their severity and the place of occurrence, hazards can be classified as disasters or not. Hazards have the potential to disrupt the living conditions of the humans; however, necessary precautions to avoid dangerous results can be taken before the hazard aggravates into a disaster.
Therefore, it can be assumed that hazard can also be a precursor to a disaster. Therefore, we can avoid the worse outcomes of a disaster that might follow a hazard if we take good disaster management steps.
What is a Disaster
A disaster has more negative consequences, unlike a hazard. Disaster is a degree of a hazard that has become more threatening. Therefore, a disaster can be defined as an occurrence that completely disrupts the normal life pattern of victims. In brief, a disaster is more catastrophic in nature. Furthermore, unlike a hazard, a disaster is more sudden and thus severe.
Disasters can also be categorized as natural disasters such as tsunami, tornadoes, volcanic eruption, etc., and man-made disasters like the consequence of technological hazards (for example, fires, transport accidents, industrial accidents, oil spills and nuclear explosions/radiation etc.)
However, an occurrence like a tornado in an uninhabited area will be termed as a hazard, and not as a disaster since though it still has destructive properties. This is because even though the severity of the tornado is still there, it did not cause any damage or loss to human life and property as it occurred on an inhabited area.

1. A disaster is defined as a serious disruption that exceeds a society's ability to cope using its own resources, and can be classified by speed of onset or cause as natural or man-made.
2. Key terms in disaster management include hazard, risk, and vulnerability. Causes of disasters include poverty, population growth, and environmental degradation.
3. Disasters can be meteorological, topographical, or technological in origin. The disaster management cycle includes preparedness, response, recovery, prevention, and mitigation. Victims are classified from primary to fifth level survivors.
DM b.tech 7th sem.pptx
The document discusses disaster management for a civil engineering course. It defines a disaster as a serious disruption that exceeds a community's ability to cope using its own resources. Hazards are dangerous events that can cause damage and are categorized as natural, man-made, or socio-natural. Natural hazards include cyclones and earthquakes, while man-made hazards result from human activities like industrial accidents. Socio-natural hazards have both natural and human causes, such as floods exacerbated by blocked drains. Vulnerability depends on the likelihood of damage from a hazard due to physical exposure and socioeconomic factors. Capacity refers to the resources and strengths that enable communities to prepare for and recover from disasters.
