Operations at India's busiest port, Kandla, have been affected by the powerful earthquake which devastated western India on Friday, but small ports nearby survived the impact and are operating normally, according to shipping industry sources and government officials. M Pinto, secretary of the Shipping Ministry, said some godowns, or warehouses, at the Kandla port were badly damaged. A signal station at the port was also damaged but had resumed operating by late Friday. Normal operations at Kandla port could resume by Saturday or early Sunday after ensuring that the shipping channel serving the port is clear, he said. Kandla handles 17 percent of the cargo passing through India's 12 largest ports, according to shipping industry data.
