Iskenderun

Iskenderun is a 231,926-person city with a 70.9-million-ton blast radius. When its port caught fire after the 6 February 2023 earthquakes, containers toppled, freight was diverted toward Mersin, and one of Turkey's three biggest cargo gateways briefly disappeared from service.

Officially, Iskenderun is a low-lying district center on Hatay's gulf coast, nine metres above sea level. It sits below the Amanos mountains and remains the province's main port city. What that standard description misses is how tightly the city binds steelmaking, shipping, storage, customs, and hinterland transport into one shoreline system.

That system is large enough to matter well beyond Hatay. Transport ministry data show the Iskenderun regional port authority handled 70.9 million tons of cargo in 2025, the third-highest total in Turkey after Aliaga and Kocaeli. Isdemir, the city's anchor steel producer, says it has annual capacity of about 5.8 million tons of liquid steel plus 3.5 million tons of flat products. Put those together and Iskenderun looks less like a provincial city than an exchange node for coal, slab, energy cargo, containers, and finished steel moving between Anatolia and global markets.

The Wikipedia gap is concentration. Iskenderun works because complementary assets sit almost on top of one another: port berths, mills, depots, truck routes, and customs facilities. That makes the city efficient in normal times and brittle in shocks. Mersin's emergency role in 2023 showed what redundancy looks like in practice: not spare capacity inside Iskenderun itself, but another coast absorbing the shock. That is the managerial lesson hidden in the map. Concentrated logistics nodes create national dependency long before they look large.

The mechanism is keystone-species dynamics stressed by phase transitions and judged by redundancy. Remove a node like Iskenderun and the surrounding commercial ecosystem does not lose one city; it reorganizes its flow. The closest biological analogue is mycorrhizal fungi: a hidden exchange layer that looks secondary until you cut it and discover how much of the forest's traffic was moving through it.
