FIELD: construction.

SUBSTANCE: invention relates to transport of hydrocarbons in oil and gas industry and may be used in operation of pipelines arranged in areas with possible landslip phenomena, to take timely measures for their protection against damage in case of soil displacement caused by disturbance of weight balance as a result of seasonal thawing, saturation of soil with water or other reasons. The device to record motion of soil in areas with possible landslip events along a pipeline installation route comprises a body, a metering lever, a hinged joint, a unit of movements count, a recording unit. The metering lever comprises a fixed anchor and N movable links, connected to each other with hinged joints, number of links depends on depth of unstable rocks that make up a landslip.
