After the earthquake an increased scientific interest in seismology and geology, as well as new thinking on engineering and building construction, emerged. Today buildings in San Francisco are largely earthquake proof. In fact, during the earthquake in 1989, the Transamerica Pyramid in San Francisco swayed more than a foot but was not damaged.
From an insurance perspective, the losses challenged existing perceptions about risk and its management, and raised many questions about coverage, exclusions, causes of loss, loss adjusting and loss wordings. But it also saw the industry embrace advances in these fields, leading to the sophisticated building and risk modelling practices which help to protect against the devastating effects of such a severe earthquake.
A century later, Lloyd’s has in place a range of Realistic Disaster Scenarios (RDS) which act as loss modelling tools and provide estimates of syndicates’ exposures to a range of events. If a similar event were to happen in San Francisco today, the estimated loss would be around $60 billion. This takes into account residential property losses of $27 billion, commercial property losses of $27 billion, workers’ compensation losses of $5 billion and auto losses of $1 billion.
