使用Davenport-Milne方法对20世纪70年代加拿大国家建筑规范的定量地震危险性图进行了评估。Cornell-McGuire方法被用来编制加拿大最近的地震危险性图。这些方法综合了地震活动性、震级-重现关系和地震动（或响应）衰减关系的信息。前者保存并完全依赖于历史地震活动的细节;后者将历史地震活动的不规则空间发生模式平滑到震源区。此外，还开发了尝试将这些方法的保留和平滑方面结合起来的Epicentral Cell方法。然而，尚未调查所采用的假设对估计的定量地震危险性的影响。本研究提供了一个比较的地震危险性评估使用上述方法和基于模拟的算法。分析结果表明，总的来说，达文波特-米尔恩方法。
The quantitative seismic hazard maps for the 1970s National Building Code of Canada were evaluated using the Davenport–Milne method. The Cornell–McGuire method is employed to develop recent seismic hazard maps of Canada. These methods incorporate the information on seismicity, magnitude-recurrence relations, and ground motion (or response) attenuation relations. The former preserves and depends completely on details of the historical seismicity; the latter smoothes the irregular spatial occurrence pattern of the historical seismicity into seismic source zones. Further, the Epicentral Cell method, which attempts to incorporate the preserving and smoothing aspect of these methods, has been developed. However, the impact of the adopted assumptions on the estimated quantitative seismic hazard has not been investigated. This study provides a comparative seismic hazard assessment using the above-mentioned methods and simulation-based algorithms. The analysis results show that overall the Davenport–Milne method ...
