Abstract

The MIKHNEVO small aperture array of the NORES type (MHVAR) was installed in the central part of the East European Platform (EEP) in 2004. A short description of array configuration and instrumentation is provided. We consider two aspects of the contribution of the MHVAR data to the recording of seismic events in the EEP. First, we discuss three recent earthquakes on the EEP and compare focus solutions received by the Geophysical Survey RAS and MHVAR jointly and independently. The travel-time and back-azimuth residuals for MHVAR coincide well with the source-specific station corrections, evaluated earlier for the stations within the Platform. The second aspect deals with the location and identification of weak local events at distances of up to 500 km from MHVAR. In 2007, MHVAR independently recorded 623 local events with magnitudes (ML = 0.79–3.24) which are identified as quarry blasts.
