MORON, Venezuela, June 25 (Reuters) - Venezuela's Moron Petrochemical Complex, the country's second largest in operation, was restarting on Thursday after a preventive shutdown due to quakes that affected the area, leaving infrastructure damages, the chief of firefighters in that area said.

Workers from the complex had been told not to come in while an initial assessment on damages was conducted, sources from that center had said earlier, adding that a leak from a storage tank had been detected on Wednesday.
