An explosion hit a chemical plant on Saturday night in eastern China, the official Xinhua state news agency said citing local authorities.
No casualties have been reported yet, Xinhua said.
The blast, which triggered a fire, happened around 8.50pm local time in Huantai county in Shandong province.
The explosion occurred at a factory of Shandong's Runxing Chemical company, according to the official People's Daily.
More than 10 fire engines were at the scene trying to put out the fire, the People's Daily reported, citing an eyewitness.
Windows shattered in the village where the blast occurred, state media said, and tremors reverberated within 2 kilometres (1 mile) of the site of the explosion.
The blast follows the August 12 chemical warehouse explosion in the northern Chinese port of Tianjin. At least 121 people were killed in that disaster, while another 54 remain unaccounted for.
The cause of the Tianjin disaster is still under investigation, although state media reports say the warehouse storing sodium cyanide and other dangerous chemicals was located too close to residential areas and may have obtained falsified safety approvals.
