Yep - it was many hundreds of tons. Based on comparing with other records, I'd wager both explosions together likely approached a kiloton of TNT. One of the larger (possibly?) non-military explosions ever. Compared with this video for 100 tons of TNT [1], the explosion in Tianjin was a few times larger. And there were two explosions, with the second being significantly larger. Also, compare with other explosions on this list [2]. The AZF explosion [3] was listed at 20-40 tons of TNT. The Tianjin explosion was far larger. ~20 tons of TNT worth of energy was converted into a seismic wave - the rest (the majority) of the energy was dispersed above ground.
