Disasters are broadly classified into two categories: natural disasters and manmade (or anthropogenic) disasters. While natural disasters include events such as earthquakes, floods, and hurricanes caused by natural forces, manmade disasters are the result of human negligence, error, or malicious intent. These events can be equally devastating, leading to loss of life, environmental damage, and economic disruption.
In this article, we explore what constitutes a manmade disaster, list common examples, explain the difference between natural and manmade disasters, and highlight the importance of disaster management in handling human-induced calamities.
What is a Manmade Disaster?
A manmade disaster refers to a catastrophic event that is directly caused by human actions. Unlike natural disasters, which are often unpredictable and uncontrollable, manmade disasters typically occur due to human negligence, technological failure, poor planning, or deliberate actions such as terrorism or warfare.
These disasters may affect infrastructure, health systems, the environment, and society at large. They often have long-term consequences and can be prevented or minimized through better governance, training, and risk assessment.
Examples of Manmade Disasters
If you’re asking “Which of the following is considered a manmade disaster?” — here are some of the most common examples:
1. Industrial Accidents
Industrial disasters occur due to failures in industrial processes, poor safety standards, or chemical spills. A tragic example is the Bhopal Gas Tragedy (1984) in India, which claimed thousands of lives due to a gas leak at the Union Carbide pesticide plant.
2. Nuclear Accidents
These include disasters such as Chernobyl (1986) and Fukushima (2011). Human error, poor planning, or equipment failure in nuclear facilities can lead to radioactive contamination with global consequences.
3. Terrorism
Terrorist attacks such as the 9/11 attacks in the USA or the 2008 Mumbai attacks in India are deliberate acts of violence intended to cause maximum destruction and fear.
4. Oil Spills
Oil spills, such as the Deepwater Horizon spill (2010) in the Gulf of Mexico, cause long-lasting damage to marine ecosystems and coastal economies. These incidents usually stem from operational negligence or technical failure.
5. Fires
Major fires caused by electrical faults, industrial negligence, or arson are also considered manmade disasters. These can include wildfires started by human activity or massive urban fires like the Grenfell Tower fire (2017) in London.
6. Deforestation and Environmental Degradation
Although gradual, the large-scale destruction of forests and ecosystems due to human activities is a manmade disaster with far-reaching implications on biodiversity and climate change.
7. War and Armed Conflicts
Armed conflicts, civil wars, and military invasions lead to destruction, displacement, and humanitarian crises. These are large-scale manmade disasters with both short-term and long-term effects.
8. Transport Accidents
Major train derailments, airplane crashes due to technical or human error, and highway pile-ups can be classified under manmade disasters.
9. Cyber Attacks
Though relatively new, cyber disasters like ransomware attacks on national infrastructure or financial systems are emerging manmade threats in the digital age.
How to Identify a Manmade Disaster?
When analyzing a disaster, ask the following:
-
Was it triggered by human activity?
-
Did it result from negligence, poor maintenance, or oversight?
-
Could it have been prevented with proper planning or regulation?
If the answer is yes, the event likely qualifies as a manmade disaster.
Difference Between Natural and Manmade Disasters
| Feature | Natural Disaster | Manmade Disaster |
|---|---|---|
| Cause | Natural forces (e.g. earthquake, tsunami) | Human activity (e.g. industrial accident, terrorism) |
| Predictability | Often unpredictable | Some are preventable and predictable |
| Examples | Earthquake, cyclone, flood | Bhopal gas leak, Chernobyl, 9/11 attacks |
| Prevention | Limited | Often preventable with safety and planning |
| Responsibility | Natural | Human |
The Importance of Disaster Management for Manmade Calamities
Manmade disasters, while tragic, offer a crucial opportunity to improve preparedness and mitigation strategies. Countries must invest in disaster risk management to:
-
Prevent industrial accidents via strict safety regulations.
-
Strengthen cyber security to reduce vulnerability to attacks.
-
Improve urban planning and emergency evacuation protocols.
-
Train first responders and civilians in disaster response.
-
Monitor environmental threats through early warning systems.
India’s Approach to Manmade Disaster Management
India has witnessed several manmade disasters including:
-
Bhopal Gas Tragedy
-
Uttarakhand forest fires
-
Mumbai train blasts
-
Delhi building collapses
To address such incidents, the National Disaster Management Authority (NDMA), under the Prime Minister of India, plays a central role. The NDMA works with other agencies like the NDRF (National Disaster Response Force) to:
-
Implement disaster risk reduction (DRR) strategies
-
Create standard operating procedures (SOPs)
-
Conduct regular drills and simulations
-
Promote community awareness programs
India’s Disaster Management Act, 2005 also provides a legal framework to deal with both natural and manmade disasters.
Manmade Disaster Case Studies
1. Bhopal Gas Tragedy, India (1984)
One of the worst industrial disasters in history, a gas leak at the Union Carbide pesticide plant in Bhopal led to over 15,000 deaths and long-term health issues for thousands. It was caused by poor safety practices and lack of accountability.
2. Chernobyl Nuclear Disaster, USSR (1986)
A nuclear reactor explosion in Chernobyl resulted in massive radioactive contamination, displacing over 300,000 people and causing thousands of cancer deaths.
3. Beirut Explosion, Lebanon (2020)
Improper storage of ammonium nitrate at a port warehouse caused a massive blast that killed over 200 people and injured thousands.
These examples show how a combination of negligence, poor policy enforcement, and lack of transparency can lead to catastrophic consequences.
Conclusion
So, which of the following is considered a manmade disaster? Any disaster caused by human activity, including industrial accidents, terrorism, nuclear mishaps, transport disasters, and environmental degradation, qualifies. Unlike natural disasters, these can often be predicted and prevented through better planning, regulation, and awareness.
Understanding the causes, impact, and prevention strategies of manmade disasters is essential for building resilient societies. With the rise of new threats such as cyber attacks and climate-induced risks, our approach to disaster preparedness must evolve continually.
