Wow, what an explosion, I hope that there not too many lives lost
What the "stupidity" is concerned, doesn't happen only in the DR. A few years ago there was a huge explosion at a plant near a little village not that far from where we lived in Europe. There were construction works going on for the plant and they hit a large gas pipe under the surface.
That pipe was not on the drawings of the architect in charge, that pipe should have been on the drawings since it lay on Industrial ground so even worse mistake from the responsible organisation who is in charge of gas pipe lines in Belgium.
It wasn't on the drawings and it didn't also stated that it was a MAIN pipe line.
The pipe started to leak due to the drilling above and some working began to sniff the gas but nobody understood that it was a main pipe so they called in some technicians and fireman to stand on hold.
In the mean time a big gasbubble had build up under the ground and when the technicians tried to weld the pipe again, the disaster happened, it exploded, killing almost 30 fireman and workers of the plant in close proximity and killing and wounding badly another 100 people of the nearby village in a few seconds.
Such disasters are alway's the sum of little mistakes put together, you cannot blame one single person or something for that.
I hope really for the people of Santiago in that area that they got out in time.
