Abstract

This report presents a review of the rainfall and landslides in Hong Kong in 1993 and provides details of the notable landslides. Rainfall during 1993 was moderate for while of the year and the annual rainfall was 6% higher than average. The intense rainfalls in September and November were sharply contrast by the very dry weather during July, August and October of the year. Four Landslip Warnings were issued in 1993, during the heavy rainstorms of 11 and 12 June, 16 and 17 June, 25 to 27 September and 5 November. There were 295 genuine landslide incidents reported to the GEO during the year and the damages resulting from these incidents are: six injuries and one fatality, 204 squatter huts were evacuated (53 temporarily and 151 permanently), seven buildings were temporarily evacuated, and 225 sections of road, pedestrian pavement and access were blocked. The large number of landslides in 1993 can be directly related to the high rainfall in June, September and November. Over one-fourth of the landslides were judged to be related to poor slope maintenance.
