Global energy magnitude catalog 2011-2023 with event selection driven by Mw Geofon

This archive disseminated through the GFZ-Data Service includes both results and information as-sociated to Bindi et al. (2023). In particular, the archive includes a seismic catalogue reporting ener-gy magnitude Me estimated form vertical P-waves recorded at teleseismic distances in the range 20°≤ D ≤ 98°, following Di Giacomo et al (2008, 2010). The catalogue is built considering 6349 earth-quakes included in the GEOFON (Quinteros et al, 2021) catalogue with moment magnitude Mw larger than 5 and occurring after 2011. Tools used to compute the energy magnitude are free available. In particular, we used stream2segment (Zaccarelli, 2018) to download data from IRIS (https://ds.iris.edu/ds) and EIDA (Strollo et al., 2021) repositories, and me-compute [Zaccarelli, 2023) to process waveforms and compute Me. The methodology applied to me-compute is also implemented as add-on for SeicomP (GFZ and Gempa, 2020) in order to allow the real time computation of Me (https://github.com/SeisComP/scmert).

本通过GFZ数据服务（GFZ-Data Service）分发的归档数据集，包含与Bindi等人（2023）相关的研究成果及配套信息。具体而言，该归档数据集包含一份地震目录，其中记录了基于远震距（teleseismic distances，范围为20°≤D≤98°）范围内记录的垂直向P波（vertical P-waves）估算得到的能量震级（energy magnitude, Mₑ），该估算方法参考了Di Giacomo等人（2008、2010）的研究方案。该地震目录以GEOFON目录（Quinteros等人，2021）中的6349次地震为基础构建，入选地震的矩震级（moment magnitude, Mw）均大于5，且发生于2011年之后。用于计算该能量震级的工具均可免费获取：本研究使用stream2segment（Zaccarelli，2018）从IRIS（https://ds.iris.edu/ds）与EIDA（Strollo等人，2021）数据仓库中下载观测数据，并使用me-compute（Zaccarelli，2023）处理波形数据并计算Mₑ。此外，me-compute所采用的方法还被开发为SeisComP（GFZ与Gempa，2020）的附加插件，以实现Mₑ的实时计算（https://github.com/SeisComP/scmert）。
