The United States Geological Survey’s Prompt Assessment of Global Earthquakes for Response (PAGER) alert system provides rapid (10–20 min) but general loss estimates of ranges of fatalities and economic impact for significant global earthquakes. FEMA’s Hazus software, in contrast, provides time-consuming (2–5 h) but more detailed loss information quantified in terms of structural, social, and economic consequences estimated at a much higher spatial resolution for large domestic earthquakes. We developed a rapid hybrid post-earthquake product that takes advantage of the best of both loss models. First, though, we conducted a systematic comparison of loss estimates from PAGER with Hazus for all significant, relatively recent, domestic earthquakes for which adequate loss data exist—augmented by a dozen ShakeMap scenarios. The systematic comparison of Hazus and PAGER losses provided the basis for selecting the specific loss metrics to present from each system. The signature product will serve as a supplement to the widely deployed PAGER alert product for significant domestic earthquakes.

基于联合 USGS PAGER 和 FEMA Hazus 损失估计系统的国内地震影响警报协议

美国地质调查局的全球地震响应快速评估 (PAGER) 警报系统提供了对重大全球地震的死亡范围和经济影响的快速（10-20 分钟）但一般的损失估计。相比之下，FEMA 的 Hazus 软件提供耗时（2-5 小时）但更详细的损失信息，根据结构、社会和经济后果进行量化，以更高的空间分辨率估计国内大地震。我们开发了一种快速混合地震后产品，它利用了两种损失模型的优点。不过，首先，我们对 PAGER 与 Hazus 的损失估计进行了系统比较，这些比较针对所有存在足够损失数据的重大的、相对较新的国内地震——并通过十几种 ShakeMap 场景进行了增强。Hazus 和 PAGER 损失的系统比较为从每个系统中选择要呈现的特定损失指标提供了基础。该签名产品将作为广泛部署的国内重大地震 PAGER 警报产品的补充。
