In my opinion, there are three types or categories of high-level disasters. Natural, technological, intentional. Any of these can damage infrastructure, property and human life.

The key elements of a disaster

Regardless of the type of event, disasters have some key elements in common:

  1. They can be very unexpected, even if some have been warned.

2. assistance, emergency services and services may be unavailable and/or overloaded.

3. may endanger life, health and the environment.

4. In the aftermath of a disaster, needs often exceed what can be provided by others.

Understanding your vulnerability

Assess your own vulnerability. This will enable you to prioritize preparedness measures and set up effective actions.

That’s helpful:

  • Identify the most common disasters
  • identify the potential hazards with the most serious consequences
  • Examine the current and/or historical impact of
  • Find out what you can expect from the impact of the disruption (e.g., services and length of recovery).

Examples of potential damage to infrastructure

Transportation

  • Lack of damage assessment
  • No departure or evacuation from the area
  • Rescue workers were unable to reach the victims
  • Police prevented civil unrest in some areas
  • Firefighters prevented the fires from
  • The flow of necessary supplies (food, water, etc.) has been interrupted.
  • Roads are closed and/or impassable

Structures

  • Damaged critical facilities that cannot function normally (e.g., airports, hospitals).

Communication Systems

  • Victims cannot ask for help
  • Family and friends cannot communicate
  • Communication with emergency services may be disrupted.

Utilities

  • performance loss
  • Damaged hydraulic infrastructure
  • Increased risk of fire or electric shock
  • Limited access to fuel, e.g., pumps not allowed to operate.
  • Loss of contact between victims and service providers

Water Service

  • Insufficient water supply, resulting in overflowing water and making it difficult to extinguish the fire.
  • Increased risk to public health

Fuel supply

  • Increased risk of fire or explosion if a fuel line breaks.

Financial Services

  • ATMs not working
  • Credit card systems are not functional

What’s the point? Well, as I often do here, to get people thinking about preparation. There are different kinds of disasters. Some are more likely than others. They all have different probabilities of happening. We usually prepare for the most likely ones first, because some are very unlikely.

Take the time to think about your own regional or personal chances of experiencing a particular disaster. Many things are out of your control. But you are in control of your preparedness.

Frequently asked questions

What are the three areas of vulnerability?

Different Types of Vulnerability The following table summarizes four different types of vulnerability – humanitarian, physical, economic and environmental – and the direct and indirect losses associated with them.

What are the risks in the event of a disaster?

Vulnerability is the inability to resist or respond to hazards when disaster strikes. … We call this economic vulnerability. Similarly, a wooden house may be less vulnerable to collapse in an earthquake, but more vulnerable to fire or a hurricane.

What is vulnerability and what are the types of vulnerability?

Vulnerability describes the characteristics and conditions of a community, system, or asset that make it susceptible to the adverse effects of a hazard. There are many aspects of vulnerability due to various physical, social, economic and environmental factors. Neglect of environmental stewardship.
