PROBLEM TO BE SOLVED: To provide a landslide recorder which is low in cost, has higher reliability, and allows easy data collection. SOLUTION: The landslide recorder includes two supports placed in a region where a landslide is expected. One support fixes one end of a wire, while the other support rotatably installs a pulley 8, around which the other end of the wire is wound while maintaining tension. The pulley is connected to a drum 2 around which recording paper 3 is attached to convert a change in the distance between the two supports into the rotation of the drum, while a pen 4, moving in the longitudinal direction of the drum at a constant speed, is brought into contact with the recording paper to record the change in the distance between the two supports. In particular, conversion means for converting the rotation of the drum into an electrical signal, processing means for processing the electrical signal, and a memory for recording processed data are provided, wherein the data recorded in the memory are externally readable with a memory card or the like.
