    Gas leak at a chemical plant. Industrial failure. The gas explosion (comparatively small) caught some nearby chemical tanks on fire and the firefighters couldn't put them out in time, which led to a second, much more massive explosion.

      Thank you for the update. This is really disheartening, but at least it's not an attack or something of the ilk.
