Processed Chinese Waveforms

This supporting information provides the processed waveforms data recorded in Chinese stations. The origin seismic data recorded at the vertical components of the dense regional broadband seismic stations in China were from the Data backup center of Institute of Geophysics, China Earthquake Administration (IGCEA). In back-projection procedure, we eliminate some noisy data by setting a coefficient threshold of 0.4. In the compressed package with format of ZIP, there are processed waveforms data of all M ≥ 7.0 shallow earthquakes that occurred in and around Japan from 2008 to 2016. The waveforms are named as *<strong>.</strong>????<strong>.</strong>V (‘*’ and ‘????’ represent name of network and station, respectively. ‘.V’ is postfix form of data.).本辅助信息提供了中国台站记录的经处理波形数据。本次使用的中国区域密集宽带地震台站垂直分量原始地震数据，源自中国地震局地球物理研究所（Institute of Geophysics, China Earthquake Administration，IGCEA）的数据备份中心。在反投影处理流程中，我们通过设置0.4的系数阈值剔除了部分噪声数据。 本ZIP格式压缩包中包含2008年至2016年日本及周边区域发生的所有震级M≥7.0浅源地震的经处理波形数据。波形文件命名格式为*<strong>.</strong>????<strong>.</strong>V（其中‘*’与‘????’分别代表台网与台站名称，‘.V’为数据后缀）。
