在开发新的地震数据处理方法的过程中，对潜在事件和相关信号的验证可能会对算法性能的评估造成重大障碍，特别是在检测阈值降低的情况下，导致包含更多的人为信号。在这里，我们提出了两个14天的地震事件目录，一个是使用犹他大学地震台站网络数据开发的本地尺度目录，另一个是使用国际监测系统数据开发的全球尺度目录。每个目录都是手动构建的，以全面识别来自所有来源的事件，这些事件可以使用地震台站的相位到达时间和方向信息进行定位，与现有目录相比有了显着的增加。新目录还包含具有挑战性的事件序列（在检测和定位阈值处的频繁余震和小事件）和新颖的事件类型和来源（例如，仅次声事件和长壁采矿事件），这使得它们对算法测试和开发非常有用，并且对它们所包含的独特的构造和人为事件序列也很有价值。
During the development of new seismic data processing methods, the verification of potential events and associated signals can present a nontrivial obstacle to the assessment of algorithm performance, especially as detection thresholds are lowered, resulting in the inclusion of significantly more anthropogenic signals. Here, we present two 14 day seismic event catalogs, a local‐scale catalog developed using data from the University of Utah Seismograph Stations network, and a global‐scale catalog developed using data from the International Monitoring System. Each catalog was built manually to comprehensively identify events from all sources that were locatable using phase arrival timing and directional information from seismic network stations, resulting in significant increases compared to existing catalogs. The new catalogs additionally contain challenging event sequences (prolific aftershocks and small events at the detection and location threshold) and novel event types and sources (e.g., infrasound only events and long‐wall mining events) that make them useful for algorithm testing and development, as well as valuable for the unique tectonic and anthropogenic event sequences they contain.
