This new blast might be a hoax.
Agree, I’ve seen the video’s and they look close to identical.
Correction. The purported video seems to be the problem, not the actual explosion.
These links are reported to be 3 hours old.

One commenter says this is a repost of the Tianjin explosion. Having seen posts of the Tianjin explosion, I agree that it follows a similar sequence—fire, small explosion, and giant explosion. If this is today’s Lijin explosion, then a remarkable similarity. One Youtube I looked at was definitely a repost of Tianjin.
It may be a few more hours before the media find someone who actually had a live picture of the explosion. The Tianjin video was shot apparently by English speakers at a hotel or apartment.
