Fe+ Brine Solution forcing by Earth Tides

[Squatchmichae]

Here is a esoteric problem that is totally unique in nature: Taylor Glacier, in the Dry Valleys of Antarctica, hosts site of a Fe²⁺ brine solution, expressed as a rusty discharge at the terminus. There is strong diurnal signals in seismic data gathered from an array co-located there, not attributable to cultural, or other geophysical inputs.

Challenge: with a median value of magnetic susceptibility for concentrated Fe brine, and assuming volumes on the order of cubic meters (not cubic km, for example), what is the maximum force or stress that a confined solution (subglacially) can exert on it's walls, driven by Earth Tides alone?

It's outside my expertise (mechanics, math mostly) but someone might have a Fermi-type solution.

I did some quick searches and found an interesting article about Taylor Glacier, which is where this brine is located. It's called Blood Falls, and from what I read it appears that this brine has been there for over a million years. This article (http://en.wikipedia.org/wiki/Blood_Falls) might provide some insights into the problem. The Earth Tides Data link provided looks like a valuable resource as well. Good luck!
