Patterns in time and space of fatal coastal cliff failures
A new analysis (Reiss et al. 2026) explores a global database of fatal coastal cliff failures, showing that these tragic events most frequently occur in the summer months when beaches are heavily populated. One significant type of fatal landslide is coastal cliff failures. Whilst I have recorded a number of these events through the years, […]
A new study published in the journal Natural Hazards and Earth System Sciences reveals insights into global patterns of fatal coastal cliff failures. Researchers examined a comprehensive database comprising 114 incidents that resulted in 292 deaths between 1927 and 2024. The analysis highlights a significant seasonal trend, with the majority of these tragic events occurring during the summer months when tourist beaches are densely populated.
The study, authored by Reiss et al. (2026), emphasizes the urgent need for better understanding and risk mitigation measures for coastal cliff failures, particularly in areas with high beachgoer numbers. While rainfall does contribute to some events, the overwhelming influence on these hazards remains the influx of people on the beach during peak summer periods.
The authors caution that climate change may exacerbate the occurrence of such events and urge heightened vigilance and precautionary measures to prevent future tragedies.
