Abstract

This report presents a general review of rainfall and landslides in Hong Kong in 1991 and provides details of the notable landslides. In summary, rainfall during 1991 was very low, the year being the tenth driest on record. The total rainfall in 1991 was 74% of the yearly average of 2,214.3 mm. One Landslide Warning was issued in 1991, during the heavy rainstorm of 15 to 16 October. There were 88 landslides and related incidents reported to the GEO District Divisions during the year and the damages resulting from these incidents are: 33 squatter huts were evacuated (seven temporarily and 26 permanently), eleven buildings were temporarily evacuated, and 21 sections of road/access were blocked. The relatively low number of landslides in 1991, and the lack of serious landslide damage, can be directly related to the exceptionally low rainfall.
