Analysis of the stability of determining the focal parameters of seismic events using the KNET network data by the programs Hypocenter, HYP, Hypoellipse, HYPO71, Dbloc2
Parameters of hypocenters and times of 4760 seismic events taken from KNET catalog compiled by the Research Station of the Russian Academy of Sciences for the period since May 2003 till the end of 2020 have been determined by different programs: Hypocenter, HYP, Hypoellipse, HYPO71, Dbloc2.

| description | Parameters of hypocenters and times of 4760 seismic events taken from KNET catalog compiled by the Research Station of the Russian Academy of Sciences for the period since May 2003 till the end of 2020 have been determined by different programs: Hypocenter, HYP, Hypoellipse, HYPO71, Dbloc2. The smallest divergence of epicenters' coordinates is observed for the earthquakes, which have happened within the area of 41°–44.5°N and 73°–77.5°E entirely covering the territory of Bishkek geodynamic test site. Such an analysis can be used to assess the quality of seismic wave arrival times determination. The best agreement is observed between the programs Hypocenter and HYP: for more than 95% of events the epicenter displacement is less than 10 km and the change of time at origin is less than 0.5 sec. This indicates the preservation of the uniformity of the KNET seismological catalog when switching from using Hypocenter to HYP as the main locator program. |
