- Floods in Tamil Nadu (November 2015): Heavy rains caused flooding in Tamil Nadu, which resulted in many deaths and significant damage to property.
- Earthquake in Killari (1993): A powerful earthquake struck Killari in Latur district, leading to the deaths of many people.
- Mumbai Deluge (July 2005): Heavy rains caused massive flooding in Mumbai, leading to a great loss of life and property.
Effects of the earthquake at Killari
The disaster at Malin village
Reasons Behind the Occurrence of Disasters:
- Floods: Heavy rains can cause rivers and lakes to overflow, leading to floods that damage homes and fields.
- Earthquakes: The shaking of the earth's surface due to movement underground can destroy buildings and roads.
- Lightning and Volcanic Eruptions: Sudden natural events, such as lightning strikes or volcanoes erupting, can cause fires and destroy areas.
- Forest Fires: Dry conditions, lightning, or human activities can cause large fires that spread rapidly and destroy forests.
- Human Activities: Human activities such as overpopulation, irregular construction, and ecological imbalance can also cause disasters.
- Terrorism and Crimes: Man-made disasters, like bomb explosions, riots, and accidents, can cause great harm to people and property.
Types of Disasters
1. Natural Disasters: These disasters are caused by natural forces, and they happen without human involvement.
For example:
- Floods
- Earthquakes
- Landslides
- Volcanic Eruptions
- Forest Fires
2. Man-made Disasters: These are disasters caused by human activities, either accidentally or intentionally.
For example:
- Bomb Explosions
- Riots and Crimes
- Ecological Imbalance
- Industrial Accidents
