The Catak landslide (Trabzon Province, Turkey) developed retrogressively upslope through a series of small slips, culminating with the catastrophic rock avalanche of 23rd June, 1988 when at least 66 people were killed. The landslide was caused by prolonged heavy rainfall triggering a failure in a partially supported 25‐m high road cutting in colluvium, which progressively removed support for the higher parts of the slope and resulted in the catastrophic slide. Such high‐magnitude events are not uncommon in the Black Sea Mountains but the recent disaster highlights the need for systematic landslide hazard assessments in the region.
