What a thunder can do...

Anytime! :)

R
 
Thought, at first, it was the tuning house for an AM, until I saw the tower had no base insulator. Then, I saw pieces of transmitters and rack equipment everywhere.
Wow!
 
As far as I know it was a typical shed used by portuguese local stations. Small diesel generator, stl receiver, transmitter... Another station in the area had the electric board toasted, nothing else... I don't know how was the franklin device, or if any...
 
If I had to take a guess, based on the amount of distruction to a masonry and concrete slab building, My guess is that the generator was not powered by diesel.

A small propane (or other LNG) tank next to the building taking a direct lightning strike that was not well grounded could easily do that kind of damage.
 
I think that cannot be the case. Tanks are not allowed to be in forest open space due to the fire prevention here in Portugal. Diesel is the mostly used for feeding generators, others are too much expensive for the locals. But yes, I have to admit that it was an hell of a shockwave that resembles a gas explosion...
 
I'm not sure I'm convinced thunder did that. The Mythbusters showed how hard it is just to break a glass window, via a sonic boom. I suspect foul play here...

I don't see any way that this could be a weather event. A tornado or microburst (straight line winds) that did that much damage to a brick structure would have brought down most of the trees in the area, and probably the tower.

The other giveaway is the debris field. Note that it appears to go in all directions, except where the mobile unit is parked, where it was deflected by the tower and the black pole next to the tower.

The most likely explanation for that pattern would be an explosion inside of the building. Diesel fuel is not volatile enough for an explosion like this. If there was no large flammable gas cylinder inside the building, then Robert's explanation of foul play is most likely.
 
I am with the old PD on this. Detonation of some type originated from inside the structure. No way weather did that.

But, im not an expert.
 
OK lightning is more believable, especially a direct strike to the shed.

Now i'm starting to feel dumb... My poor english knowledge led me to think that a thunder was the same as a lightning strike. Sorry to all of you for this misleading topic.

Being that, the event is now more likely to happen upon a near lightning strike?

And thanks to kinphoenix2, again my apologises to all.
 
Thunder is merely the sound of lightning. The actual destruction occurs from the electric current in the strike itself. Lightning will destroy anything it touches. The sound of the lightning can damage your hearing if you are close to an actual strike but not directly hit. We don't call it "a thunder" here in the U.S. We simply call it "thunder".

Usually for such small stations generally it's just a small generator fully field, if they store jerricans in the shed I don't know. Major stations have enclosed tanks, at some distance from the transmitter buiding, sometimes under the ground.
