Abstract

Two landslide-monitoring sites have been established for a minimum 2-year investigation near the villages of Pasirpari and Cibacang in southern Cianjur Regency, West Java, Indonesia. Surveyed-in lines will measure amounts of surface movement and tilt, borings that produced exploratory cores now serve as slip-surface detectors and open-pipe piezometers, and rain gages will record rainfall at both sites. Exploratory cores and field observations located upper slip surfaces ranging in depth between 4 and 14 m. Rises of borehole-water levels of as much as 63 cm during drilling suggest that pore pressures exist at the inferred-slip surfaces. Sliding along slip surfaces and slope failures occurred during the rainy season between November 1980 and April 1981.
