2020 Beirut explosion

{SNIP}

The first explosion, at about 18:07 local time (15:07 UTC), likely triggered by the stored fireworks, sent up a large cloud of smoke and a crackle of bright firework flashes, and heavily damaged the structure of the warehouse itself with a force equivalent to around 1.5-2.5 tons of TNT, the size of a mid-sized truck.

{SNIP}

A study of seismic signatures of the explosion by the Federal Institute for Geosciences and Natural Resources in Germany produced a yield estimate between 0.5 and 1.1 kt of TNT.

2015 Tianjin explosions

On 12 August 2015, a series of explosions killed 173 people, according to official reports, and injured hundreds of others at a container storage station at the Port of Tianjin.[2] The first two explosions occurred within 30 seconds of each other at the facility, which is located in the Binhai New Area of Tianjin, China.[3] The second explosion was far larger and involved the detonation of about 800 tonnes of ammonium nitrate (approx. 256 tonnes TNT equivalent).

Chinese scientists subsequently estimated that the second more powerful explosion involved the detonation of about 800 tonnes of ammonium nitrate, based on crater size and lethality radius (336 tons TNT equivalent, based on relative effectiveness factor of 0.42).[4]
