On the afternoon of March 8, a petroleum tanker named Torm Agnes entered the Port of Ensenada on Mexico’s Pacific coast carrying almost 120,000 barrels of diesel.Such a vessel was a rare sight in that port, which mainly hosts cruise liners, luxury yachts and container ships. Ensenada lacks the infrastructure needed to unload cargos of flammable hydrocarbons safely – making what happened later that day odder still.Waves of fuel-hauling trucks rolled up to the dock to cart away much of the Torm Agnes’ load.
