Abstract

The local magnitude scale ML was refined for the western part of the Eurasian Arctic on the basis of data from seismic stations operating on the archipelagos of Svalbard, Franz Josef Land, and Severnaya Zemlya: –logA0(R)=1.5*log(R/100)+1.0*10(–4)*(R–100)+3.0. Refinement was carried out on the basis of a sample of 167 earthquakes and 612 amplitude values at 5 seismic stations. The sample covered earthquakes that occurred in the main seismically active zones of the Eurasian Arctic for the period from January 2016 to April 2019. The refined scale can be applied in wide ranges of epicentral distances and magnitudes. The ML scale with the corresponding station corrections will be introduced into the practice of daily processing of seismological data from the western part of the Eurasian Arctic.
