Some of you guys may be interested in this.

My neighbour (a STRANGE lady)... has dug a massive channel, nearly a foot wide and about 2 feet at least deep, along the boundary fence line. My house is above hers on the gentle slope, and we have red clay sitting on shale (paid for soil tests years ago). Our houses are about 10 feet apart.

We cycle thru drought and flooding rains in Australia, ya know!

A few years ago, I fund her at midnight (during a wet period) praying to the Goddess of the earth chanting 'please drive this evil from my land' - in order to stop the water flowing down the hill thru the soil... she then finished this little ceremony complete with lit candles and sprigs of herbs tied to the fencposts, with a rousing version of Onward Christian Soldiers...

Incidentally, she has also excavated about 1 ft down around her foundations (brick and concrete pillars max 2 ft deep - and around the front corner on my side, she has undermined totally one corner, where she has also neatly installed an extra down-pipe from the gutter - which was overflowing and dumping water thru the roof into her house...) which hold up a weather-board timber frame house about 40-45 years old, because she wanted to 'keep the foundations dry'...

She has written to me complaining that my watering my garden bed along the boundary was causing water damage to her foundations, as she can see cracks inside her house (fibro) walls... btw, she has stripped off the top 2 feet of topsoil as well as the contents of this trench and spread them on her garden beds. Also her house has a 'corrugated fibro' roof - nice and brittle by now I should think...

We are now in a serious drought situation, and soil is moving...

My question is, based on you guys technical experience, is just when should I sell the tickets for the big event of watching her house collapse?
