ABSTRACT:
An apparatus for detecting soil movement is disclosed generally comprising an elongated housing which is inserted downwardly into a bore hole drilled in the soil. The housing generally has a rectangular configuration and is disposed within the hole so that the cross-sectional longitudinal axis is parallel to the direction of soil movement and so that the length of the housing is disposed substantially perpendicular to the directon of soil movement. The housing is provided with an anchor means at the lower end thereof which anchors the housing in stable soil to prevent movement of the housing itself. A plurality of vertically spaced soil movement detectors are provided along the length of the housing and include outwardly extending wings. A plurality of indicators are provided at the upper end of the housing and are operatively connected to the detectors by linkage means so that movement of the detectors by soil movement cause the indicators to indicate the amount of soil movement as detected by that particular detector.
