The data is the near seismic waveform of nangabawa short period dense seismic array, which contains the original seismic waveform and the preprocessed seismic waveform. The original data are the seismic waveforms cut according to four near earthquake events (Ms 5.2 in Tangshan, Hebei, Ms 5.4 in Huocheng, Xinjiang, Ms 4.2 and Ms 4.0 in Bomi, Tibet). The waveform length is 120s before P wave and 1800s after P wave. Preprocessing includes re-cut the waveform (- 20-100s), band-pass filtering (the frequency band range used in Tangshan, Hebei and Huocheng, Xinjiang is 0.1-1hz, and Bomi, in Tibet is 0.1-2hz), rtrend, rmean, and the ZNE component is rotated to the ZRT component. The quality of the data is good.The fine structure of underground lithosphere can be analyzed by near earthquake waveform.

File naming and required software

The folder name "seismic event time. 0" represents the original seismic waveform corresponding to the seismic event;
The folder name "time frequency range of seismic events" represents the preprocessed seismic waveform corresponding to seismic events; For example, "2020-07-11-22-38-25_0.1-1" represents the seismic waveform corresponding to the 2020-07-11-22-38-25 seismic event after preprocessing (BP range is 0.1-1hz)
The seismic waveform data is stored in sac format, and the name of the file is "seismic event time. station name. component name. Sac". For example, "2020.07.11.22.38.25.RU5464.BHE.sac" represents the E component waveform of the seismic event at RU5464 station at the time of July 11, 2020.22.38.25.
