Central Portugal Weird Loud Booms

This shit is driving me nuts. Since 3 or 4 o'clock we have these BOOM! every hour, sometimes it's one boom each 10 or 15 minutes.

Today/tonight it's stormy, but these are NOT thunders, they sound like HUGE bombs going off, really loud BOOM!! and thats all, not a lightning, not a single thunder sound, these ones really seem close, say, like next to us!

WTF. Been asking people all day long what is going on and NO ONE knows what is this. Even in social media no one knows... and they think these are just thunders... but honestly? never heard in my 40 years life a thunder going off pretty much like a SINGLE bomb!

Anyways, just putting it out like it is.
