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 *.????.V (‘*’ and ‘????’ represent name of network and station, respectively. ‘.V’ is postfix form of data.).
