This report presents a general review of rainfall and landslides in 1987, and provides details of the notable landslides. In summary, rainfall amounts for various durations during 1987 can generally be considered as normal except for the heavy long-period (more than two days) rainfalls during the latter half of July. Over the whole year, 307 landslides and related incidents were reported to the GCO District Divisions and the damages resulting from these incidents are: seven persons injured, 197 huts evacuated, five buildings partially closed, 44 flats evacuated and 81 sections of road and access closed. Most of these damages occurred during or shortly after rainstorms. The most intense and damaging storm occurred on 29-30th July, when 111 incidents occurred. A Landslip Warning was issued on this occasion. The warning was also issued for the other two severe rainstorms on 6th April and 22nd May.
