Frequently Asked Questions
What is the difference between a natural hazard and a natural disaster?
A hazard is a potential threat to life and property, whereas a disaster is the actual occurrence of that threat that causes widespread destruction and overwhelms local capacity to cope.
Are droughts considered sudden disasters?
No, droughts are slow-onset disasters that develop gradually over a prolonged period due to a deficiency in precipitation.
Why is Punjab vulnerable to floods?
Punjab is drained by several rivers like the Sutlej, Beas, and Ravi, and heavy monsoon rainfall combined with poor drainage can cause rivers to overflow, leading to floods.
