ABSTRACT
Predicting the size and frequency of landslides is essential in landslide risk assessment. Records of past landslides can provide some information on what has happened, but are invariably incomplete and often provide little or no guidance on less frequent events that may occur. In landslide risk assessment, one of the most important questions to ask is what might happen in the future and often judgements have to be made about the likelihood of infrequent events with serious consequences with little, or no help from historical records.
