Traveltime Inversion for the Earthquake Focal Depth based on the Inner Core Phases PKIKP and pPKIKP Time Differences

This dataset contained the codes and seismogram records associated with 2022GLO98624. (1) The raw seismograms of Chile, 2014-08-23 22:32:22 UTC, and Bolivia, 2017-02-21 14:09:04 UTC, which recorded at a seismic array deployed at Guangxi, China. (2) the GMT plotting shell and the python codes for earthquake depth determination.

The input file format for determing the depth of an earthquake is in the follow:

taking Bolivia_EHB.dat as an example:

line1 -->  evla (event latitude)  evlo (event longitude)  evdp (event depth)

line2 -->  number of station (ns)

line3, 1 of ns --> stla, stlo,  dt

......

_________________________________________

evla:  event latitude

evlo:  event longitude

evdp: event depth

stla:   station latitude

stlo:   staion longitude

dt:     pPKIKP minus PKIKP
