Our transcription: Initial attempts to control the slide activity centered around the insertion of numerous three foot wide concrete and steel nails at the base of the slide.
When these efforts proved unsuccessful, the focus then changed to strategies for living with the slide, which in some places had shifted homes as much as 200 meters from their original positions.
One of the more visible approaches was putting utilities, such as gas and sewer lines above ground in order to prevent rupture.
Unfortunately, most of the homes of the area had already become virtually uninhabitable.
Of the 156 houses built here, most have been torn apart by the shifting ground or relocated to other areas.
