Abstract

This report presents a general review of rainfall and landslides in 1986, and provides details of the notable landslides. In summary, rainfall amounts for various durations during 1986 can be considered as normal except for slightly heavier short period (less than one day) rainfalls on 6th June. Over the whole year, 233 landslides and related incidents were reported to the GCO District Divisions, and the damage resulting from these incidents are: one person injured, 167 huts evacuated, seven buildings partially closed and 58 sections of road and access closed. Most of these damages occurred during or shortly after rainstorms. The five most intense and damaging storms occurred on 12th May, 6th June, 4th July, 12th July (Typhoon Peggy) and 11th August. The Landslip Warning was issued on each of these five occasions.
