Abstract. Among the multitude of magnitude scales developed to measure the size of an earthquake, the surface wave magnitude MS is the only magnitude type that can be computed since the dawn of modern observational seismology (beginning of the 20^th century) for most shallow earthquakes worldwide. This is possible thanks to the work of station operators, analysts and researchers that performed measurements of surface wave amplitudes and periods on analogue instruments well before the development of recent digital seismological practice. As a result of a monumental undertaking to digitize such pre-1971 measurements from printed bulletins and integrate them in parametric data form into the database of the International Seismo- logical Centre (ISC, www.isc.ac.uk, last access: August 2021), we are able to recompute MS using a large set of stations and obtain it for the first time for several hundred earthquakes. We summarize the work started at the ISC in 2010 which aims to provide the seismological and broader geoscience community with a revised MS dataset (i.e., catalogue as well as the underlying station data) starting from December 1904 up to the last complete year reviewed by the ISC (currently 2018). This MS dataset is available at the ISC Dataset Repository at https://doi.org/10.31905/0N4HOS2D.

100 多年重新计算的浅层地震面波震级

摘要。间量值量表的大量开发用于测量地震的大小，面波震级MS是可以因为现代观测地震学的黎明来计算的唯一大小类型（开头的20^个世纪）用于全球大多数浅层地震。这要归功于台站操作员、分析员和研究人员的工作，他们在最近的数字地震实践发展之前就在模拟仪器上进行了表面波振幅和周期的测量。作为将 1971 年之前印刷公告中的此类测量数字化并将其以参数数据形式整合到国际地震中心 (ISC，www.isc.ac.uk，最后访问时间：2021 年 8 月) )，我们可以重新计算MS使用大量台站并在数百次地震中首次获得它。我们总结了 2010 年在 ISC 开始的工作，该工作旨在为地震学和更广泛的地球科学界提供从 1904 年 12 月开始到最后一个完整年份的修订后的 MS 数据集（即目录和基础台站数据）。 ISC（目前为 2018 年）。该MS数据集可在 https://doi.org/10.31905/0N4HOS2D 的 ISC 数据集存储库中获得。
