Local slab penetration into lower mantle controls deep-focus seismicity and Changbaishan volcanism in northeast China

The dataset for the manuscript consists of five data files: (1) the P-wave velocity model (Vp.xyz), (2) relocated earthquake locations (event_reloc.dat), (3) selected earthquake focal mechanisms from the global CMT catalog (focal_gcmt.dat), (4) P-wave arrival times (absolute.dat), and (5) station information (station.txt). (1) The P-wave velocity model file (Vp.xyz) includes five columns: longitude, latitude, depth (km), velocity values (km/s), and velocity perturbations relative to the initial model. (2) The relocated earthquake locations file (event_reloc.dat) contains ten columns: event ID, longitude, latitude, depth (km), year, month, day, hour, minute, and second. (3) The selected earthquake focal mechanisms file (focal_gcmt.dat) comprises thirteen columns: longitude, latitude, depth (km), strike1, dip1, rake1, strike2, dip2, rake2, the exponent part of the scalar moment, newX, newY, and title. For more details, please refer to the Global CMT website (https://www.globalcmt.org). (4) The P-wave arrival times file (absolute.dat) provides absolute arrival times utilized in the inversion. Each line starting with " # " indicates an event information line, where the number following " # " represents the event ID. Other lines contain observations related to the event, each comprising four columns: station, picked travel time, pick quality, and phase. (5) The station information file (station.txt) lists four columns: station name, latitude, longitude, and elevation (m).
