The shockwaves from the first explosion were equivalent to detonating three tonnes of TNT while the magnitude of the second explosion was equal to 21 tonnes of TNT.

The blasts were also visible from space - a Chinese agency released satellite photos of the area with the explosions showing as white spot. .
