Youtube filling up with them and some closer where it shows the first still quite large explosion then this beast that knocks the person recording clean off their feet.
This is a copied report but how true it is is anyones guess - you know chinese whispers and all (no oun intended).
Gas station exploded that ignited two oil
tanks nearby the chemical warehouse where chemicals exploded, the
firefighters failed to put it out and a series of explosions triggered
by the chemicals in the container terminal, all
firefighters/police, people who watching nearby die on scene instantly.
The fact that chemical is concentrated in that area, people panic and
concerns the releasing of toxic gases after the explosion, many
evacuating caused road jam.
People from 10km away can feel the shockwave, windows shattered. The
Donghai Road station is destroyed. Hospitals are overloaded with
patients.
