Why are you living under a slide area and in the middle of sour gas fields?
Sour gas fields are west and south of me and all the towns,I'm on the good side of the slide,it's hillcrest who will get buried so I'm not under a slide area,just 100 meters from where it stopped last time.;-)
All the extensiometers are on the east slope which also has 2 faults and about 500 miles of coal shafts under it so I'm not worried about being on the west side of the turtle.
Tha frank slide was caused by the coal miners and not mother nature.
Just imagine an oreo cookie with a 5 pound weight on it and what happens when you scrape out the center.
The seams lay at a 30 to 45 degree angle and mother nature starts doing her magic at about 33 degrees(natural repose) so it was inevitable that it would happen,also the natives named it Turtle mountain because it's the mountain that moves and would never camp under it and thats before it failed.
You cant see the thrust faults in this pic but the mountains folded over on itself and the big knob on the left will be the next to go,the cracks get a bit bigger every year and they dont grant building permits under it anymore because no one will insure you there now.
Heres the slide as I saw it out my window last year when a bit of action was happening.
