The utility model provides a geology landslide monitoring device, geology landslide monitoring device is awaiting measuring domatic device frame domatic and is setting up the base of slope device frame at the base of slope including being used for setting up, be equipped with between domatic device frame and the base of slope device frame have that displacement measurement holds by the measuring rope of overspeed device tensioner tensioning, the last one end of keeping away from the displacement measurement end of measuring rope links to each other with domatic device frame, is equipped with the displacement measurement part of the volume of measuring displacement measurement end displacement of being used for on the base of slope device frame. The utility model has the advantages of because the base of slope device erects and puts at the base of slope, when taking place landslide disaster, can not cause the damage to the displacement measurement part, furthest has reduced economic loss.
