Abstract.
The paper describes the automatic system for monitoring the seismicity of the
European Arctic, built on the basis of a network of seismic stations of a
different countries located in the region. The core of the system is the
software package for automatic detection and location of seismic events NSDL
developed by the authors. NSDL is designed to monitor automatically the seismic
activity of a region using a network of seismic stations, seismic arrays or
individual three-component seismic stations. The described system has two
levels. The first level includes single station processing programs that
implement algorithms for detecting and pre-locating seismic events from the
data of individual three-component seismic stations and seismic arrays. The
second level is the program of association of the results of processing for
individual stations performing joint location on the network of stations on the
basis of events and phases of seismic waves detected at the first level of the
processing. NSDL allows to use of a set of one-dimensional
layered velocity models for the location of distant events, the propagation
paths of waves from which cross regions of the medium with different velocity
properties. Decisions on the truth or falsity of the detected candidate events
are made by Bayesian classifiers, based on the evaluation of a number of
amplitude, spectral, and polarization parameters, both for single-station and
joint seismic event processing. The application of the system for seismic
monitoring in the Arctic region showed high reliability of automatic results,
significantly accelerated the process of compiling final catalogs, verified by
analysts, and significantly increased the representativeness of the resulting
bulletin due to weak events. The detailing achieved through the application of
the described system allows us to take a fresh look at the development and
structure of the seismic process in the European Arctic, in particular, to
record seismic events associated not only with tectonic processes, but also
with cryosphere destruction processes.
Keywords: seismic monitoring, seismic
location, seismic event detection, western Arctic.
