According to a Canadian government database, landslides are the most common type of disaster that occurs in the province of British Columbia. Recently there has been a trend in British Columbia toward using quantitative risk assessments to estimate life-loss risk at landslide hazard sites, and to compare these estimates with risk tolerance thresholds to determine the necessity for, and extent of, risk management measures. These risk estimates are most often calibrated by so-called ‘expert judgment’ because historical landslide fatality data are not readily available. This article addresses this gap by summarizing available historical data to better inform expert judgment. It shows that fatalities caused by landslides in British Columbia are rare (approximately one fatality per year in the last decade) and have decreased with time despite rapid population growth. Approximately half of these fatalities in the last decade are related to debris flows and debris floods that impact houses, whereas the other half are related to rockfalls, debris flows, and debris floods that impact highways. A comparison with other hazard types in the Canadian government’s disaster database suggests that, while not particularly deadly, landslides are still important because of the economic damage and service disruptions they cause. Although the data are specific to British Columbia, the methods for identifying and presenting landslide risk trends could be modified and adopted in other world regions where landslide fatality data are collected and quantitative risk management methods are utilized.

根据加拿大政府的数据库，滑坡是不列颠哥伦比亚省最常见的灾害类型。最近，不列颠哥伦比亚省存在一种趋势，即使用定量风险评估来估计滑坡灾害现场的生命损失风险，并将这些估计值与风险容忍阈值进行比较，以确定风险管理措施的必要性和范围。这些风险评估通常是通过所谓的“专家判断”来校准的，因为历史滑坡死亡数据尚不可用。本文通过总结可用的历史数据来更好地指导专家的判断，从而弥补了这一空白。它表明，不列颠哥伦比亚省由山体滑坡引起的死亡极少发生（过去十年每年约有1人死亡），尽管人口迅速增长，但随着时间的推移却有所减少。在过去十年中，这些死亡人数中约有一半与影响房屋的泥石流和泥石流有关，而另一半与影响公路的碎石，泥石流和泥石流有关。与加拿大政府灾难数据库中其他灾害类型的比较表明，滑坡虽然不是特别致命，但由于其造成的经济损失和服务中断，仍然很重要。尽管数据是针对不列颠哥伦比亚省的，
