What in the HFS is going on?
« on: November 21, 2012, 06:00:14 pm »
So I started a new fortress, and started to dig out a fortified area...
When suddenly,

A section of the cavern has collapsed!  x3

Nearly 50 times in a row, every three seconds.

WHAT IS GOING ON?

Does your embark have an aquifer? If so, it's possible the cavern generation glitched and is causing the aquifer to leak into a magma pipe...

P.S. If you don't get this note, let me know and I'll write you another.

It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.

It's amazing how they can make an entire floodgate out of the bones of 2 cats.

Oh damn, I hate this. there's probably something odd deep underground. I had it once, but it actually stopped, leading me to create a bustling fort which crumbled due to lost save.
 
Possibly magma interacting with water, making a obsidian waterfall. Rockfall? It could just be a section of the cavern acting odd, but It wouldn't spam you quite so much. Hmm. Maybe there's a magma pipe leading into a cavern area that's leaking.

I would go into the configs and set the Cave-in notice to not center and pause until you can figure out exactly what, as you've stated, the HFS is going on.

I find that fairly often sections of the cavern room mysteriously collapse at embark. Having a look with dfhack's reveal tool shows no apparent reason for this. Have a peek and see what's going on.

If you have perma-falling rocks, route your fort entrance underneath the rocks.

"Hello? Dwarves? This is the elves, we know you're here because of all the clanking and rumbling!"
"WE CAN'T HEAR YOU, COME CLOSER"
"Well, okay! What could go wrong?"
*splat*

"THIS BE GOBLINS. YOU FORT DOOMED!"
"Oh no! Don't come any closer!"
"HA HA HA WE COME CLOSELY ANYWAY! DISOBEY DWARFS!! DIE IN HELL!!"
"Oh no! They're almost to the entrance!"
"HA HA HA Hsplat"

Won't the pipe eventually cool over, as the magma above gets supported and plugs the gap? Eventually?

Not necessarily.  If the water is falling into the center of a magma pipe, it creates obsidian that ultimately falls into the semi-molten rock at the bottom of the pipe.  When it hits the semi-molten rock, it disappears without a trace.  So it'll never fill up and plug.  The only way for it to plug would be for the water to fall onto the edge, and the cause the walls to bulge out and eventually block the pipe partway up.

Not always if water's coming in at really bad angles ( cavern overhang over magma pipe, through intercavern passengeway, etc ), it's rare, though.

It should normally, eventually seal over, but those other events can happen and end up with eternal rockfall.
