Abstract:
The paper aims to define an appropriate magnitude calibration function and station corrections of PV (PVS) wave for broadband (BB) instruments of the National Operative Telemetric System for Seismological Information (NOTSSI). The calibration function is defined by an adaptive treatment of the existing calibration function for the short period seismometers. The existing magnitude station corrections are reconsidered in level and the corrections for the new broadband stations are determined. The values of the adapted calibration function and the new set of station corrections have to be considered as a necessary step for realization of practical comparative proof of NOTSSI magnitude determinations regarding the assessments of the international seismological centres as EMSC, NEIC or ISC.
