Prompt Assessment of Global Earthquakes for Response

PAGER (Prompt Assessment of Global Earthquakes for Response) is an automated system that produces content concerning the impact of significant earthquakes around the world, informing emergency responders, government and aid agencies, and the media of the scope of the potential disaster. PAGER rapidly assesses earthquake impacts by comparing the population exposed to each level of shaking intensity with models of economic and fatality losses based on past earthquakes in each country or region of the world. Earthquake alerts – which were formerly sent based only on event magnitude and location, or population exposure to shaking – now will also be generated based on the estimated range of fatalities and economic losses. PAGER uses these earthquake parameters to calculate estimates of ground shaking by using the methodology and software developed for ShakeMaps. ShakeMap sites provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and disaster planning.

PAGER（全球地震响应提示评估）是一个自动化系统，旨在生成有关全球重大地震影响的内容，为紧急响应人员、政府及援助机构以及媒体提供潜在灾难范围的资讯。PAGER通过将暴露于各等级震感强度的人口与基于该国或地区历史地震的经济损失和人员伤亡模型进行比较，迅速评估地震影响。地震警报——过去仅基于事件震级和位置，或震感暴露人口——现在也将基于估计的伤亡人数和经济损失范围生成。PAGER利用这些地震参数，通过采用为ShakeMaps开发的方法和软件，计算地面震动估计值。ShakeMap站点提供重大地震后地面运动和震动强度的实时地图。这些地图被联邦、州和地方公共及私人组织用于地震后的响应与恢复、公共和科学信息，以及应急演练和灾害规划。
