Q. What is Kallakkadal, recently seen in news?
Answer:
Coastal flooding caused by swell waves
Notes: High sea waves, termed swell waves, have flooded coastal homes in Kerala, known locally as Kallakkadal or swell surge. Occurring primarily during pre-monsoon and sometimes post-monsoon, Kallakkadal results from distant storms generating ocean swells. Coined by fishermen, Kallakkadal signifies the sea's thief-like arrival. These waves originate from the southern Indian Ocean, taking several days to reach Kerala's coast. UNESCO recognized the term in 2012, highlighting its significance in describing this coastal flooding phenomenon.
