was at 8 a.m. local time and was caught on a surveillance camera. Luckily the buildings had been evacuated beforehand and no one was hurt in the blast.
However more than 430 buildings in the area, including homes close by, were damaged in the explosion.
The Japanese police and fire department are investigating the cause of the massive explosions.
The police report that there were no dangers of toxic leakages and the flames were brought under control by the fire department around 15 hours after the second explosion.
