Following a governmental decision to build a national earthquake early warning system (EEWS) named TRUAA, the Geological Survey of Israel has upgraded the national Israeli Seismic Network with more than 100 stations countrywide. The stations are spread mainly along the main hazardous fault systems of the Dead Sea and Carmel‐Zfira, which potentially may produce Mw 7.5 earthquakes. Currently the system is shifting from the deployment phase into a testing phase in which the earthquake point‐source integrated code (EPIC) EEW algorithm is used. During the deployment phase, real‐time performance of the EEW algorithm has steadily improved, with alert delays (span between origin time and EEW alert time) reduced down to 3 s in some cases. We present an overview of TRUAA, the performance of EPIC during the deployment phase and during playbacks of historic events, as well as our suggested alert approach for Israel.

TRUAA-以色列地震预警系统：实施情况和现状

在政府决定建立名为TRUAA的国家地震预警系统（EEWS）之后，以色列地质调查局升级了国家以色列地震台网，在全国范围内设有100多个站点。这些台站主要分布在死海和卡梅尔-兹菲拉（Carmel-Zfira）的主要危险断层系统上，这可能会引起7.5兆瓦地震。当前，系统正在从部署阶段转移到测试阶段，在该阶段中，将使用地震点源集成代码（EPIC）EEW算法。在部署阶段，EEW算法的实时性能稳步提高，在某些情况下，警报延迟（始发时间与EEW警报时间之间的跨度）降低到3 s。我们概述了TRUAA，
