Well, I think if we're comparing this to similar incidents from the past, nothing will ever quite live up to the Halifax Explosion:
https://en.wikipedia.org/wiki/Halifax_Explosion
Roughly 130 times (!) as powerful in TNT equivalent as the Tianjin explosion, and caused, among other things, a 60-foot tsunami in the harbor

(not to mention flattening most of Halifax and Dartmouth, and killing at least 2,000 people).
Quite sad to see the same sort of thing happening today in China though
