An explosion has shaken a chemical plant in the eastern Chinese province of Shandong and was reportedly felt 50km (31m) away.
Earlier this month, a series of explosions apparently emanating from a warehouse in Tianjin, China killed at least 145 people.
It was not yet known whether anyone was killed or injured.
Video showed a massive fireball light up the night sky shortly after 11pm local time on Monday.
Reported footage of the explosion was initially uploaded to Chinese social media site Weibo, but appears to be of the previous explosion at Tianjin.
RT said the blast could be seen and heard from a great distance.
Among the dead were 94 firefighters, 11 policemen and 53 civilians. Ltd., a chemical plant which handles the transport of hazardous goods, exploded on August 12.
China formally detained 12 government officials and company executives following the blasts and accused them of dereliction of duty or abuse of power.
