On November 25, 1839, an enormous cyclone caused a 40-foot storm surge that hit the ancient city of Coringa in present Andhra Pradesh. The cyclone wiped out the harbor city, destroyed 25,000 ships and vessels in its bay, and killed 3,00,000 people.
Survivors never entirely rebuilt the city. City of Coringa was known for ship building and repairing. From Coringa harbor a wide range of goods were exported to Southeast Asian countries and ships from United Kingdom, France, Netherlands and Portugal were repaired.
