Seismic observations can be used to constrain the seismic velocity structures and deformation patterns of the crust and upper mantle. The southeastern Iranian plateau is the transitional zone from subduction to collision. The study of this region can provide an important basis for understanding the dynamic progresses of the plate convergence and associated tectonic responses. The data comes from the portable seismic array deployed by this research group. The site selection requirements are strict. All stations are equipped with Trillium 120PA seismometer (120 s-175 Hz) and Taurus digital collector. This data set is the waveform data from the first 100 s to the last 200 s of the direct P wave. Event magnitudes are greater than or equal to 5.0, and epicenter distances range from 30° to 90°. The data can be used to decipher the deep dynamic processes of the subduction-collision transition zone.

File naming and required software

The seismic data is in SAC format and the file name is a_b_c.bh{x}.sac, where a is the station name, b and c are the time when the event occurred, including the day of the year, as well as the hour, minute and second, respectively. {x} can be e (east-west component), n (north-south component), and z (vertical component). The data can be read and written by softwares like SAC, Obspy, Matlab, et al.
