Dataset related to article 'The Collaborative Seismic Earth Model: Generation 2'
收藏资源简介:
This repository holds 23 earthquake simulations conducted using the second generation of the Collaborative Seismic Earth Model (CSEM2, Noe et al., submitted), serving as benchmark simulations for reproducibility. The simulations are performed with the spectral-element wave propagation solver Salvus (Afanasiev et al., 2019) on event-adapted meshes (Thrastarson et al., 2020). Accompanying waveform data from the stations can be downloaded from public FDSN services and accessed via tools such as the ObsPy mass downloader (Krischer et al., 2015). Information about the earthquakes and receivers is provided in the event files. The source-time function, a filtered heaviside for 50 - 160 s, is included in 'stf.h5' for global simulations and for 20 - 160 s for regional simulations, respectively. The event and waveform information to create Figure 4 in the manuscript are the following: a) GCMT_event_LAKE_TANGANYIKA_REGION_Mag_6.0_2017-2-24-0.h5, stf 50 - 160 s b) GCMT_event_CENTRAL_CALIFORNIA_Mag_5.6_2020-6-4-1.h5, stf 20 - 160 s c) GCMT_event_CHILE-ARGENTINA_BORDER_REGION_Mag_5.7_2018-6-21-16.h5, stf 20 - 160 s Simulations for b&c are performed on smaller domains and on regular cubed-sphere meshes.
本仓库包含23组由第二代协同地震模型(Collaborative Seismic Earth Model, CSEM2,Noe等,已投稿)生成的地震模拟数据,作为可复现性基准模拟集。本次模拟采用谱元法波动传播求解器Salvus(Afanasiev等,2019),基于事件适配网格(Thrastarson等,2020)完成。配套的台站波形数据可从公开的FDSN服务下载,并可通过ObsPy批量下载工具(Krischer等,2015)获取。地震事件与接收台站的相关信息存储于事件文件中。 源时间函数为经滤波的亥维赛阶跃函数:全局模拟的滤波频段为50~160秒,区域模拟的滤波频段为20~160秒,相关数据分别存储于`stf.h5`文件内。 用于制作手稿中图4的事件与波形信息如下: a) GCMT_event_LAKE_TANGANYIKA_REGION_Mag_6.0_2017-2-24-0.h5,源时间函数滤波频段为50~160秒 b) GCMT_event_CENTRAL_CALIFORNIA_Mag_5.6_2020-6-4-1.h5,源时间函数滤波频段为20~160秒 c) GCMT_event_CHILE-ARGENTINA_BORDER_REGION_Mag_5.7_2018-6-21-16.h5,源时间函数滤波频段为20~160秒 针对b与c的模拟,是在更小的计算域及规则立方球网格上完成的。
