The data was collected in Qiangtang (2020.11-2020.12) and Altyn-Tagh (2021.11-2022.01). Four natural seismicity, six near-earthquakes and two teleseisms were recorded by 361 short-period seismometers from Nov. 2020 to Dec. 2020. And 315 short-period seismometers recorded five near-earthquakes and two teleseisms (including the mangya earthquake with m5.3 in Qinghai province on December 19, 2021) from November 11, 2021 to November 1, 2022. After data preprocessing (de-mean, de-linear trend and taper), we cut the events recorded by the seismometer with a fixed width of 1500s from the time of earthquake occurrence for each seismic event(i.e., the time range of each seismic event data is [begin, begin +1500s]). For the active source signals recorded, since the node instrument records continuous signals for a month, the signals recorded by each instrument are intercepted according to the initiation time and location, and the seismic records for 200s are intercepted from the initiation time. After time correction, data of each shot were de-mean, de-linear trend and taper.

File naming and required software

Natural source signal:
The name of the folder storing data is "yyyy-mm-ddThh-mm-ss". "yyyy" indicates the year when the earthquake occurred. "mm" indicates the month and "dd" indicates the number of days. T is an interval, and "hh-mm-ss" indicates the hour, minute, and second when the earthquake occurred. The folder is named as "station no. YYYY-MM-DDTHH-MM-SS". Sac ", the station information and source information have all been written into the sacfiles.
Active source signal:
(Medium-grade explosive) 1000kg-2000kg. Station and explosives' longitude and latitude have been written sacfiles' head.
Naming rule: name of explosive _trace.sacch
Usage: Seismic data with "sac" format for storage, can rely on the sac program (http://ds.iris.edu/ds/nodes/dmc/forms/sac/) to read operations
